Paul Laurienti, M.D., Ph.D. - Addressing Health Disparities of Farmworkers and their Families
June 12, 2019
Paul Laurienti, M.D., Ph.D., uses advanced imaging and analysis techniques to study structures within the brain and personal exposure data to explore and understand links between pesticide exposure and brain development.
“I’m interested in looking beyond what part of the brain turns on or off with a particular task, and thinking about how parts interact with each other to control how we perceive things or how we think,” said Laurienti.
As the Director of the Laboratory for Complex Brain Networks (LCBN) at Wake Forest School of Medicine, Laurienti leads an interdisciplinary group of scientists, graduate students, and staff to study the brain as an integrated system. The LCBN was established in 2009 by Laurienti and Jonathan Burdette, M.D., to expand a new field in brain research called network science. Network science is an analysis method for investigating the human brain in terms of a network of interconnected components. “Network science has been a valuable tool for us to assess brain structure and function. We’ve been able to analyze brain networks under different conditions, including environmental exposures and alcohol use disorder.”
Leveraging Collaborations to Understand how Pesticides Impact the Brain
In 2013 Laurienti began a collaboration with Thomas Arcury, Ph.D., through the NIEHS ViCTER program. Arcury had been leading an NIEHS-funded research project called Preventing Agricultural Chemical Exposure (PACE) since 1997. The PACE project is a community-based participatory research project focused on Latino farmworkers who are exposed to pesticides.
Laurienti was able to contribute neuroimaging expertise to examine the neurocognitive and behavioral effects pesticide exposure on adult Latino farmworkers. “The ViCTER award is the reason why I am doing my current research. I am a neuroscientist, so before this collaboration I was not involved in pesticide exposure research. The ViCTER program has enabled us to combine unique research perspectives to understand this problem,” said Laurienti.
Laurienti now leads the current phase of the project, PACE5, which is exploring how pesticide exposure is related to brain development and neurocognitive functions among Latino children. This longitudinal study is following children of Latino farmworkers for two years and comparing them to children of nonfarm working Latino parents with comparable socioeconomic status.
In order to measure pesticide exposure in the children, Laurienti teamed up with Kim Anderson, Ph.D., at Oregon State University. Anderson has developed simple wearable silicone wristbands that act as passive sampling devices by capturing personal exposure to thousands of different chemicals. The team will then use behavioral assessments and cutting-edge brain imaging techniques to explore links between pesticide exposure and brain development.
“Ours will be the first study that I can find that utilizes longitudinal measurements of pesticide exposure and advanced brain imaging in children to examine the effects of pesticide exposure,” said Laurienti.
Building Trust and Providing Actionable Results
With the exception of neuroimaging, most of the data collected for Laurienti’s pesticide exposure studies are acquired through the community.
“It has been fascinating to learn how different it is to conduct research out in the environment where the exposures are happening, rather than just in the laboratory,” said Laurienti. “I’ve learned through this process how crucial it is to build trust with community partners who can help engage our participants and identify trusted interviewers and data collectors.”
Laurienti and his research team often share their scientific findings with the community, particularly, to the study participants themselves. By reporting back results, study participants and their families can benefit from his research efforts.
“Providing study participants with our research findings is really rewarding for me. It brings the value of our research back to them and empowers them to take action,” said Laurienti.
Advancing Research Through Data Sharing
A key component of Laurienti’s research moving forward is improving data management and data sharing. In collaboration with Ramon Casanova, Ph.D., Laurienti is trying to transform the way people look at brain networks and how scientists can build on each other’s research.
“Instead of focusing on specific spots in the brain, it will be more like looking at a road map and thinking about the connections between points,” he said. “We’re trying to transform the data from individual points into what we call trajectories and standardize it in a way that will allow us to compare across different studies or populations.”
By sharing these new brain network trajectories, Laurienti hopes that researchers will be able to leverage older studies and compare across different research projects to answer complex questions about how the brain works.
Maida Galvez, M.D. – Empowering Pediatricians to Address Children’s Environmental Health Needs
May 15, 2019
NIEHS-funded researcher, Maida Galvez, M.D., an associate professor of environmental medicine, public health, and pediatrics at Mount Sinai, strives to increase awareness of the link between environmental exposures and health. By forging partnerships and translating science on pediatric environmental health, she is helping clinicians and families take action to protect children’s health.
Galvez was motivated to specialize in children’s environmental health during a seven-year B.S./ M.D. biomedical program at the City University of New York, and through a residency in social pediatrics at the Children’s Hospital at Montefiore in the Bronx. These experiences led her to apply for a competitive fellowship training program in environmental pediatrics at Mount Sinai which involved working on Growing Up Healthy in East Harlem, an NIEHS-funded study led by Mary Wolff, Ph.D. Through these experiences, she saw firsthand how neighborhoods can shape health.
“Seeing connections between substandard housing, poverty, and neighborhood health led me to think about community-level concerns, and how that impacted children’s health,” said Galvez.
Emphasizing Environmental Health in Pediatric Practice
Galvez co-directs the Community Engagement Core (CEC) for the Mount Sinai Transdisciplinary Center for Early Environmental Exposures where she collaborates with an interdiscplinary team of healthcare professionals to identify environmental health concerns and connect vulnerable populations to needed interventions. Her work has focused on serving children from high poverty neighborhoods around New York City, such as East Harlem and the Bronx. Many of the children she serves suffer from health conditions which are known to be related to air quality, housing quality, exposure to certain chemicals, and other factors related to their environment.
“There are many upstream root causes of health conditions in children, and the environment is one of them,” said Galvez. “For the busy clinician, it’s difficult during a 15-minute well child visit to address how the home environment and larger community impacts health.”
To overcome these challenges, Galvez, CEC Co-Director Carol Horowitz, M.D., and the CEC team collaborate with the Region 2 Pediatric Environmental Health Specialty Unit (PEHSU) at Mount Sinai and a newly established statewide network called the New York State Children’s Environmental Health Centers (NYSCEHC). These entities serve as important clinical translational arms for the CEC.
Through PEHSU and NYSCEHC, a team of experts at Mount Sinai work together with social workers, asthma counselors, and allied health professionals to systematically identify environmental causes of health outcomes, especially asthma. They then link families to local community-based organizations that can provide a healthy home intervention. For example, homes with mold concerns may be investigated for water leaks, proper ventilation, and suitable water drainage. After the intervention, relevant information is included in the patient’s Electronic Health Record, ensuring coordinated care and communication among clinicians, community-based organizations, and public health agencies.
“Our team has championed a broader consideration of social determinants of health to include the assessment of the home environment to promote healthy homes,” says Galvez.
Raising the Profile of Environmental Health Needs
Galvez also aims to translate knowledge about environmental health concerns to broader audiences, including the public and the medical community. Through the CEC, she has collaborated with environmental health scientists, clinicians, community organizations, policymakers, and others to develop and disseminate key environmental health messages.
For example, through an NIEHS P30 Administrative Supplement award, the Mount Sinai CEC is working with other CECs across the country to update the American Academy of Pediatrics and Physicians for Social Responsibility’s Prescriptions for Prevention. The Mount Sinai CEC's page also provides a variety of fact sheets, infographics, videos, and other resources about a variety of potentially harmful exposures.
“We seek to shift the way the pediatric practices operate by championing inclusion of environmental health,” said Galvez.
One sign they are already achieving this goal is that recommendations championed by the CEC and partners made it into the most recent version of Bright Futures, a national health promotion and prevention initiative led by the American Academy of Pediatrics.
Expanding the Vision of Children’s Environmental Health
Galvez says a key success for the CEC has been its ability to improve collaboration across diverse fields and expertise.
“Our experience with shared learning and cross-fertilization has been phenomenal. We’re bringing partners together that typically haven’t been present in these efforts,” said Galvez. “Our team has made meaningful strides to integrate a greater consideration of the environmental determinants of health into clinical care.” Moving forward, she aims to continue addressing the environmental health needs of families, particularly those that are high risk. “The global vision is that we meaningfully integrate environmental health into the routine medical care of children of all ages, and that healthy environments are prioritized and seen as integral to children’s overall health,” said Galvez.
Courtney Carignan, Ph.D. – Working With Diverse Communities to Explore Environmental Health Impacts
April 19, 2019
Courtney Carignan, Ph.D., knows the importance of community input in environmental health research and has shaped her work to meet the needs and concerns of communities. Carignan, an assistant professor at Michigan State University (MSU), has measured contaminants and assessed health effects for a wide range of populations including infertile couples, pregnant women, infants, new mothers, office workers, gymnasts, and communities exposed to contaminated drinking water.
Responding to Community Concerns
Her work with communities began during her first job out of college coordinating response to trichloroethylene contamination in drinking water in a rural Pennsylvania community.
“I got to know the people in the community and talk with them about their questions and concerns,” Carignan said. “From that experience, I resolved to find a way to better respond to and assist exposed communities.”
Now at MSU, Carignan is working with communities in New England and Michigan to characterize PFAS exposures and understand potential health effects from exposure in drinking water. PFAS are manufactured chemicals used in products for stain and water resistance, as well as in foams for fighting fuel fires. They have contaminated the drinking water of over 6 million Americans including that of several communities near where she is working. After PFAS contamination was discovered in these communities, Carignan started using her research to help answer community questions about the extent of the exposure and how it may be affecting the health of children.
“I’m currently investigating the effects of PFAS from contaminated drinking water on children’s immune systems and helping create an educational resource for exposed communities,” she said. “I’m also providing technical assistance for communities here in Michigan, as well as for the state health department.”
Carignan is part of a new NIEHS Research to Action grant focused on links between PFAS exposure and impaired vaccine response and other effects on the immune system in children, in collaboration with Northeastern University professor Phil Brown, Ph.D., and Laurel Schaider, Ph.D., of the Silent Spring Institute. Working in two communities who have experienced PFAS contamination in their drinking water, the researchers are measuring PFAS and markers of immune response in blood and interviewing community members to document experiences of affected communities. They are also developing an online network with resources for community education and engagement.
Unique Insight Into Gymnast Exposures
Carignan also has an ongoing project focused on assessing and reducing exposures to flame retardants in gymnasts. This work started when she was an NIEHS-funded doctoral student at Boston University under the guidance of Tom Webster, Ph.D., where she worked on a project to examine flame retardant exposures in office workers.
“From that work, I learned that flame retardants were used in polyurethane foam,” Carignan said. “As a former gymnast, I became concerned that flame retardants may be used in the foam of gymnastics training equipment, including the loose foam pit and landing mats.”
Most gyms contain a large pit filled with hundreds of foam polyurethane blocks, which provide a soft landing for gymnasts learning new acrobatic moves. Carignan initiated a small study to examine this potential exposure. She found that female gymnasts in her study, who were training at a collegiate gym in the eastern United States, had four to six and a half times more flame retardants in their blood compared to the general U.S. population. She also found that handwipe samples from the gymnasts after practice contained two to three times more flame retardants than before practice. Extremely high levels of flame retardants in dust, air, and foam from the gym suggested that the foam blocks were an important source of exposure.
Based on these findings, she started thinking about how to reduce exposure for gymnasts and collaborating with gymnasts, gym owners, and suppliers to understand the sources of flame retardants in gyms and ways to reduce exposure. Carignan started the Gymnast Flame Retardant Collaborative to facilitate communication between research scientists, fire safety experts, equipment manufacturers, and the gymnastics community.
“The collaborative provided a mechanism to engage with the gymnastics community,” Carignan said. “By forming a group, we were able to discuss the problem and find ways to solve it together.”
With support from the Toxics Use Reduction Institute at the University of Massachusetts Lowell, Carignan led an Intervention Study to see the changes flame retardant exposure in gymnastics training facilities when foam pits are replaced with flame retardant-free foam. Through this study, in collaboration with several other researchers including Heather Stapleton, Ph.D. an associate professor at Duke University, she observed a five-fold decline in flame retardant exposure for gymnasts. In collaboration with fire safety experts, they were also able to provide a check list for gyms describing how to meet all fire safety requirements and assure fire safety in gyms without the need for flame retardants in the foam.
Investigating Important Exposures in Communities
“My research focus is motivated by concerns of the communities I work with, loved ones who have encountered infertility, and as a woman, parent, and conscientious consumer,” Carignan said. She has also been part of several other studies focused on exposures and health. For example, as part of her postdoctoral work, Carignan worked on an NIH-funded study led by Russ Hauser, M.D., Sc.D., where she discovered an association between organophosphate flame retardants in urine and negative in vitro fertilization (IVF) outcomes in women. Her publication describing these links was chosen as an NIEHS 2017 Paper of the Year.
In support of her innovative approach to research and engagement, Carignan was named as one of 20 Pioneers under 40 in Environmental Public Health by the Collaborative on Health and the Environment. She was chosen for her accomplishments in driving environmental health science in new directions and promoting work that will protect the health of children, families, and communities.
“I’m really proud to be named among colleagues that I admire so much.” Carignan said. “The award helped me feel that the extra effort it takes to translate research into action is valued by the environmental health community.”
Staci Bilbo, Ph.D. — Bridging Basic Research and Clinical Care to Better Understand Autism
March 20, 2019
Staci Bilbo, Ph.D., studies how environmental exposures and the immune system interact in early life to impact brain development. Her research focuses on autism spectrum disorder (ASD), which affects about 1 in 59 children. As a basic scientist, Bilbo and her research team work in a lab using mouse models, but they also partner with clinicians to explore how their basic research may be relevant to understanding and treating ASD.
“I became interested in autism because of the community of parents and clinicians who were recognizing autism in their children and patients and trying to grapple with this disorder that was on the rise,” said Bilbo, who is an associate professor of pediatrics and neuroscience at Harvard Medical School and director of research for the Lurie Center for Autism at Mass General Hospital for Children. In July 2019, she will be returning to Duke University, where she was an assistant professor for nine years, as the Haley Family professor of psychology and neuroscience.
Research Path Leads to Autism and the Environment
The Immune System and the Brain
Immune molecules are critical for normal brain development. Exposure to infection, stress, or environmental chemicals during pregnancy can disrupt normal production of immune molecules during critical stages of brain development, potentially increasing the risk for ASD and other developmental disorders.
Bilbo’s path to ASD research began when she was a graduate student, curious about how the immune system interacts with other important biological systems and functions in the body. She found that factors known to impact the immune system, such as an infection or stress during pregnancy, affected brain development and behavior in offspring.
When Bilbo was an assistant professor at Duke University, she began to explore how prenatal exposure to environmental chemicals, like air pollution, and social factors, like stress, interact to influence health outcomes. “There is pretty striking evidence in the literature showing that stress makes individuals more vulnerable to the effects of air pollution,” she explained. She credits Marie Lynn Miranda, Ph.D., who at the time was director of the Duke University Southern Center on Environmentally Driven Disparities in Birth Outcomes, for encouraging her to pursue a research path in environmental health.
Bilbo and colleagues found that mice exposed to both prenatal diesel exhaust and maternal stress had worse ASD-related outcomes compared to mice exposed to stress or diesel exhaust alone. "We see a true synergy in terms of the impact on offspring if we look at outcomes like social behavior deficits or immune system abnormalities. We don't see much with just diesel exposure or stress alone, but we see a lot with the two combined,” explained Bilbo. “This finding has implications for mothers and children living in poorer neighborhoods, where both air pollution and stress levels may be high.”
With a grant from NIEHS, Bilbo and her research team continue to investigate how combined exposure to maternal stress and diesel exhaust during pregnancy may contribute to autism risk by disrupting immune molecules that are critical for normal brain development.
Moving Research Beyond the Lab
Bilbo also partners with clinicians who work with ASD patients at the Lurie Center for Autism, a treatment center for individuals with ASD and other developmental disorders. She was named director of research for the Lurie Center in 2016.
Bilbo teamed up with Lurie Center Director, Christopher McDougle, M.D., to create a unique program that brings together the postdocs and trainees working in her lab with Lurie Center clinicians. The clinical and lab groups meet once a month for a “research exchange” in which the clinicians talk about their specialty and how they care for patients, and lab students present their basic research.
This exchange helps the clinicians contribute to and stay current with the latest research around the biology underlying autism. It also encourages basic scientists to consider how the research they are doing is relevant to ASD patients. Bilbo’s postdocs and trainees also shadow clinicians to meet some of the patients and their families. “For many of my students, this is the first time they have met ASD patients and their families and grasped the clinical relevance of their research.”
Through virtual meetings and travel, Bilbo will maintain her connection with the Lurie Center when she moves to Duke University in July. She also hopes to establish a research exchange program with ASD clinicians and researchers at Duke and will continue working with her research team in Boston through a small satellite lab. “I'm feeling very optimistic because I think this type of collaboration is the way science should be – there's no way we're going to solve a problem like autism by confining it to a single city, place, or lab.”
Brian D. Smith II – Increasing Awareness for a Healthy Detroit
March 8, 2019
Brian Smith, a community relations specialist at the Center for Urban Responses to Environmental Stressors (CURES) at Wayne State University in Detroit, Michigan, helps to raise residents’ awareness of how to protect their health from environmental stressors.
Having grown up in Detroit’s industrial corridor, where residents face serious health threats from air pollution, Smith is not only passionate about raising awareness but also understands the culture and how best to connect with community members. Smith and the CURES team are working in collaboration with community partners to address environmental health concerns in Detroit’s urban landscape, such as poor air quality due to high truck traffic, lead-contaminated soil and water, and abandoned homes and buildings that create an unsafe environment.
Leveraging Community Partnerships to Build Capacity
Smith got his start in community outreach in 2013 when, as a returning combat veteran for the Michigan National Guard, he began work as an AmeriCorps volunteer with Focus: HOPE, a nonprofit in Detroit addressing hunger, poverty, inadequate education, and racial divisiveness.
He was able to leverage the partnerships and skills he built while at Focus: HOPE when he joined CURES in 2015. “I feel really proud that through my work with CURES I’ve been able to continue to give back to Focus: HOPE,” noted Smith. “They were interested in learning about the health impacts of a proposed concrete recycling facility in a neighborhood with high poverty and high asthma rates, and we were able to help address that need.”
Smith worked with CURES researchers and community partners to host an environmental health literacy session to review exposure and health impact data with the residents, who then used this information when they met with the board of zoning.
“Rather than using the term ‘empower,’ I think of this work as helping people to stand in their own power by way of giving them more knowledge and connecting them to community services and resources,” Smith stated.
Bringing Research to Detroiters Through Environmental Health Chats
One way Smith helps to foster collaborations and co-learning experiences for environmental health advocates, healthcare professional, stakeholders, leaders, and researchers is through public forums and mobile environmental health chats.
Smith’s innovative forums and workshops bring environmental health information to the places community members already gather, such as churches, schools, and community centers.
CURES hosts these public forums for 80 to 100 people several times per year. The forums include presentations from researchers on the current science as well as presentations from the Community Advisory Board members or community partners, such as Detroiters Working for Environmental Justice, Ecology Center, Zero Waste Detroit, Detroit Health Department, Breathe Free Detroit, Southwest Detroit Environmental Vision, and provide residents with information and resources. These presentations are recorded so that the information can be accessed at any time. In addition, Smith uses these presentations to host mobile environmental health chats for approximately 80 community members two to three times per year.
Guided Environmental Health Tours
To see Detroit’s environmental health issues up close, Smith provides Environmental Health Tours to nursing students, medical residents, environmental law students, visiting researchers, and community partners. The stops on the tour highlight CURES research interests and areas of concern for the CURES Community Advisory Board, such as petroleum coke exposure in Southwest Detroit, community gardens, and the neighborhood around the trash incinerator.
“One of our stops is the neighborhood I grew up in. When we were on a tour last fall, I knew the driver of the ice-cream truck that drove by because he was the same driver when I was growing up,” Smith noted. “I feel honored to continue to be a steward to my community as well as a conduit to for bi-directional information sharing between CURES and the community.”
Planning for the Future
Smith is currently completing his Master in Urban Planning degree at Wayne State University and will graduate in December. Given the direct relationship between the urban and industrial environment in Detroit and the environmental health disparities in the city, he hopes to bring this unique planning perspective to his work to continue to make a difference to the residents of Detroit.

Kim Harley, Ph.D. – Engaging Latino Youth in Environmental Health
February 20, 2019
Kim Harley, Ph.D., reproductive epidemiologist, is passionate about improving environmental health literacy, training, and leadership skills in Latino youth of Salinas, CA.
California’s Salinas Valley is one of the most productive agricultural regions in the nation, with annual revenues exceeding $4 billion per year. According to Harley, more than 9 million pounds of agricultural pesticides are applied to crop fields in the Salinas Valley per year.
An Associate Director of the NIEHS-funded Center for Health Assessment of Mothers and Children of Salinas (CHAMACOS) study, Harley leads projects that utilize community-based participatory research approaches to address pesticide and other environmental exposures experienced by immigrant farmworker women and their children living in the Salinas Valley. In other words, she works with community residents at every stage of the research process -- from defining the research questions to collecting data, analyzing and communicating results and implementing interventions.
Harley has been committed to the CHAMACOS study since it began in 1998, while she was a graduate student at the University of California at Berkley.
“The CHAMACOS study was funded during my M.P.H. and I was really excited about the possibility of working on the study as part of my Ph.D., which is why I applied to the Epidemiology program at Berkeley. I joined Drs. Brenda Eskenazi and Asa Bradman when they were first starting the study,” said Harley.
CHAMACOS is the longest running longitudinal birth cohort study of women and children in a farmworker community, containing years of data characterizing the effects of environmental exposures on children’s neurodevelopment, behavior, and other health outcomes and amassing hundreds of thousands of biospecimens. As research participants transitioned from children into adolescents, new questions and ideas concerning the study arose from Harley and her team. This led to the formation of the study’s youth council.
The CHAMACOS Youth Community Council
In 2010, Harley helped establish the CHAMACOS Youth Council (YC) in collaboration with partners from Clinica de Salud del Valle de Salinas, a local network of community health clinics. This leadership group trains 10 to 15 Latino youth in research design and implementation, promotes environmental health literacy, and engages them in advocacy and outreach.
“Our youth council work started with funding from NIEHS, so we are really proud and grateful to NIEHS for starting and believing in this project,” said Harley.
To date, Harley has worked as the principal investigator to oversee several successful research projects led by the YC, including the Health and Environmental Research in Make-Up of Salinas Adolescents (HERMOSA) Study and the Chamacos of Salinas Evaluating Chemicals in Homes & Agriculture (COSECHA) Study, each of which was 3 years long. The vast majority go on to college. A new cohort of the YC is currently working on a project examining Latina’s exposures to potentially hormone disrupting or carcinogenic chemicals in cleaning products.
Youth Participatory Action Research
According to Harley, youth engagement in participatory science and evaluation requires dedicated research and community partners. These partners assist with strategic planning, devote adequate time for learning and training, revise and critique research design strategies, recruit participants, interpret findings, and translate these findings into actions. Shared decision making is also an integral part of youth research, ranging from initial decisions on the research concept and study design to the final decisions on dissemination and intervention. This process empowers youth researchers to lead, develop ownership and become fully vested in the study.
Youth-engaged participatory science and evaluation also provides positive professional development opportunities for youth, improved self-esteem, as well as exposure to environmental research and institutes of higher education. Often these youth develop research skills and leadership abilities, which empower many to pursue careers in public health and environmental law.
“We are really interested in training the next generation of environmental health leaders in the Salinas farm worker community,” said Harley.
The HERMOSA Study
The first YC-led project Harley oversaw with her community partner, Kimberly Parra, was the HERMOSA study. The study examined 100 Latina adolescent’s exposures to endocrine-disrupting chemicals (EDCs) in cosmetics and beauty products. EDCs are molecules, natural or synthetic, that mimic, block or interfere with the function of hormones in the body.
This three year study, funded by the California Breast Cancer Research Program, was the first to demonstrate that choosing personal care products labeled free of phthalates, parabens, triclosan and benzophenone-3 (BP-3), can significantly reduce personal exposure to some EDCs.
The YC under the direction of Harley, has communicated these scientific findings to both local and national communities through major news broadcasts and educational materials. Efforts by the YC to reduce exposure to EDCs have also included: writing petitions on media platforms, writing letters to CEOs of major drugstore chains, creating DIY beauty recipes, educating policy makers in Sacramento, and presenting scientific data to the California Consumer Product Safety Commission.
The COSECHA Study
In 2016, the YC in collaboration with Harley and community partner, Jose Camacho, conducted the COSECHA Study. This three-year project funded by the California Breast Cancer Research Program, assessed pesticide exposure in Latina adolescents living in Salinas Valley. The YC members collected all data from 100 participants including: residential dust samples, urine samples, GPS coordinates, nearby field crop verification, environment sampling bracelets and questionnaires.
Research findings were analyzed by Harley and her Berkeley colleagues and, with the help of James Nolan, the center’s Community Outreach Coordinator, youth researchers translated scientific discoveries into health education activities, including developing a Radio Novella Series on how to protect oneself and family from pesticides. The series has aired on 10 radio stations throughout the Central Valley, Eastern Washington and Oregon. Youth researchers have also distributed custom made doormats to individuals within the agricultural community, which the research indicated may help reduce pesticide exposures in the home. Each mat was printed with simple tips for reducing take-home pesticide exposures. In addition, youth researchers have co-presented their discoveries at scientific meetings and conferences.
Household Cleaning Products Study
Again as principal investigator, Harley has begun an intervention study with a new cohort of YC members, geared towards understanding and reducing chemical exposure in cleaning products, among Latina moms living in Salinas Valley. Harley anticipates that the results from this study will be available within the next year or two.
Sherry Baron, M.D. – Engaging the Community to Protect the Health of Low-Wage Workers
January 29, 2019
Sherry Baron, M.D., an NIEHS-funded occupational physician and public health researcher, strives to make work practices and workplaces safer, especially for disadvantaged populations. According to Baron, one of every three workers in the United States is a low wage worker and makes less than 12 dollars per hour. These workers are more likely to be exposed to hazards on the job.
Baron initially became interested in worker health during an undergraduate internship with a network of rural community health clinics serving coal miners. Since then, she has made it her life’s work to document the environmental hazards of low-wage workers and develop successful interventions to protect their health.
“I wanted to have a career where I could improve social justice,” Baron said. “I was drawn to occupational health because it was an area of medicine where I could be directly engaged with communities around issues that were important to them.”
Using Community Partnerships to Reach Immigrant Workers
Before becoming a professor of Occupational and Environmental Health at the City University of New York (CUNY), Baron spent 25 years as a researcher at the National Institute of Occupational Safety and Health (NIOSH). She had a distinguished career at NIOSH where she won several awards for her work championing occupational health for low-wage, immigrant workers. She also collaborated with NIEHS and the U.S. Environmental Protection Agency (EPA) on an environmental justice initiative called Partnerships for Communication (1994-2007), which added an occupational justice focus.
Baron also served as the coordinator for the NIOSH Occupational Health Disparities program where she helped to shift the thinking about how best to reach low-wage and immigrant workers. She found that community partnerships were much more effective than the traditional occupational health model of trying to reach low-wage workers through their workplace. “Focusing on the community and developing workplace exposure reduction programs with community partnerships has been very successful in reaching a whole group of workers that we haven’t successfully reached in the past.” Baron stated.
Building Capacity to Protect Workers' Health During Disasters
Baron applied her community-based research approach at CUNY and the Barry Commoner Center for Health and the Environment to explore how environmental exposures at the workplace and in the community can impact health.
For example, she led a research effort following Superstorm Sandy that documented the health impact of that disaster on Latinx workers who provided clean up and reconstruction efforts. (The term Latinx is now used instead of Latino or Latina to be inclusive of all genders.) Baron also designed a community engaged intervention effort to raise the profile of local immigrant community-based organizations in the New York City (NYC) disaster preparedness planning process. This work led to ongoing funding to assist community-based Latinx worker centers in developing their own capacity to conduct effective Spanish-language training to inform workers about their rights to safe workplaces.
Involving the Community to Reduce Exposure to Toxic Cleaners
Baron and her team are in the initial stages of an NIEHS Research to Action project to reduce exposure to toxic cleaning chemical products among low-wage Latinx immigrants. They are partnering with the largest Latinx immigrant community-based organization in NYC, Make the Road New York, to survey Latinx domestic cleaning workers about cleaning product use.
“Community partnerships are incredibly important for good science and for helping build capacity within community-based organizations on issues of environmental sciences.” Baron emphasized. In collaboration with co-principal investigator Homero Harari, Sc.D., researcher and assistant professor at Icahn School of Medicine at Mt. Sinai, the team is not only developing exposure measure methodology, they are also using citizen science and involving community members in the exposure assessment process.
Looking to the future, Baron is excited to find new ways to engage the communities she works with. For example, she plans to continue to build awareness about environmental exposures among communities using citizen science approaches, such as using smart phone applications for workers to document dangerous working conditions.
Thomas McKeon – Working With Schools to Address Environmental Health Needs
January 14, 2019
Thomas McKeon, a researcher and academic coordinator at the University of Pennsylvania (Penn), has a longstanding interest in environmental health literacy and community engagement. His work focuses on providing tools and education to protect vulnerable populations, especially children, in Pennsylvania from environmental toxins, such as air pollutants.
McKeon’s passion for environmental health stems from early life experiences. Throughout his childhood, he participated in a nature camp located in Pennington, New Jersey, called The Watershed Institute, first as a participant, and later as a counselor. “The institute placed a strong emphasis on understanding how environmental issues impact human health through direct exploration, such as examining water samples,” says McKeon. “For me, the connection between environmental health and human health has always been quite clear.”
His interest in further exploring this connection lead McKeon to pursue a B.S. in Ecology and Natural Resources at Rutgers University, and later an M.P.H. in Environmental Health at Penn. Now, he works closely with NIEHS grantee Marilyn Howarth, M.D., at the Community Engagement Core (CEC) of Penn’s Center of Excellence in Environmental Toxicology (CEET). Together, they work collaboratively with stakeholders to identify and solve environmental health problems for Pennsylvania communities.
Responding to High Asthma Rates in Schools
Over the past few years, one of the CEC’s key priorities has been addressing the alarmingly high asthma rates in Philadelphia. According to Philadelphia’s 2017 Health of the City report, asthma rates are two to three times higher in the Philadelphia region compared to the rest of Pennsylvania. Studies indicate that high asthma rates are linked to a variety of outdoor air pollutants from auto exhaust, power plants, airports, and oil refineries.
“Children are among the populations most affected by asthma, resulting in missed school days, activity limitation, and hospitalization,” says McKeon. “However, many residents are unaware of actions they can take to keep their children safe.”
In response, McKeon and colleagues worked with the Delaware Valley Regional Planning Commission to design a project to educate staff at early learning centers about how to protect children from poor outdoor air quality. Working together, they developed a 15-minute presentation discussing local asthma prevalence, the relationship of poor outdoor air quality and asthma, and air quality alert resources. They contacted daycare directors, asking to share the free resource with their staff.
“As we began giving the presentation, we got a lot of positive feedback, and daycares started recommending other daycares we should talk with as well,” says McKeon. From 2015 to 2017, they gave the presentation to staff at a total of 45 childcare centers in Philadelphia.
To test their approach, their team administered pre- and post- presentation surveys to measure knowledge gained about outdoor air quality and asthma. Their results show that staffers gained awareness of the U.S. Air Quality Index (EPA’s index for reporting air quality). Additionally, many daycares staffers signed up to receive alerts from AirNow.Gov, and more than half of preschool staffers said they modified daycare activities based upon air quality. For example, daycare centers were more likely to adjust time spent playing outside on code orange or red air quality alert days. “After receiving our training, staffers indicated increased knowledge about air quality and air monitoring resources,” said McKeon. “This gave staffers a sense of empowerment through improved knowledge, and encouraged positive decision-making to protect children at risk for asthma.”
To follow up on this success, their team is looking to create a similar presentation tailored for elderly populations, another group with a high risk of respiratory illness. “We like to take a living, breathing approach with our environmental educational programs, which can be modified according to changing situations and circumstances – and for diverse needs,” says McKeon.
Teaching Environmental Health Through Art
The CEC is also working in Chester City, Pennsylvania, a community just outside of Philadelphia that suffers from disproportionally high rates of asthma, cancer, and other conditions. McKeon and others recently worked with a small group of high school students in the Chester Boys and Girls Club, encouraging them to express their environmental health concerns through art.
The CEC met with students on two occasions. First, McKeon led an environmental health presentation during which they discussed lead, poor air quality, and related concerns in the region. Second, they collaborated to create personalized environmental health patches for a unified quilt.
Their quilt is made of photosensitive imprints and watercolor tiles. The quilt visually emphasizes commonalities shared among all communities, focusing on plants, streams, and open spaces. However, the mosaic of discoloration portrays the impact of environmental influences on health equity.
The CEC entered the quilt, which they titled An Equitable Earth, in the National Academy of Medicine’s nationwide Visualize Health Equity art contest, and it was selected to be featured in a permanent online gallery. “We saw an opportunity to highlight a community suffering from health disparities and environmental health inequities,” said McKeon. “We worked with students to successfully create a project through their active participation, helping young people elevate their own voices.”
Next Steps: Finding Place-Based Answers
Looking forward, McKeon plans to use geocoding and data collection in his work to answer place-based questions and formulate solutions. “This area of focus would be a natural progression from community engagement and community-based participatory research, enabling us to yield more specific exposure information,” said McKeon. “For example, we could better answer questions, like: How is air pollution from traffic impacting asthma rates in specific communities?”
McKeon says CEC’s successes would not be possible without the help of NIEHS. “The institute has played an invaluable role to help us improve environmental health in Pennsylvania’s most vulnerable communities, and I’m delighted to be a part of these efforts,” says McKeon.
