Shrinking Salton Sea Threatens Children's Respiratory Health, Say NIEHS Grantees
Children living in Imperial Valley, California, have higher rates of respiratory problems compared to children elsewhere in the U.S., according to a survey conducted by NIEHS-funded researchers from the Environmental Health Sciences Core Center at the University of Southern California (USC). The survey is part of a larger community-based research project to understand how dust from the drying Salton Sea may be affecting children's respiratory health.
"The communities near the Salton Sea are some of the poorest in California and already face disproportionate environmental health disparities. As the Salton Sea shrinks and air quality is expected to worsen, we want to understand what that means for local communities and how to best protect public health," said Jill Johnston, Ph.D., who is co-leading the project with Shohreh Farzan, Ph.D.
Johnston and Farzan surveyed parents of first and second graders at four elementary schools near the Salton Sea. They found high rates of respiratory problems: up to 43% of parents said their children experienced wheezing, and up to 30% said their child had asthma. According to Farzan, these rates are much higher than state and national averages.
Agricultural runoff from nearby farms is the main source of water for the Salton Sea. As runoff from farms decreases, the lakebed is exposed and turns to dust. Wind blows the playa, or dry lakebed, dust into nearby communities, contributing to poor air quality.
Working with Comité Cívico Del Valle, a local environmental justice organization, the researchers collected dust and soil samples to better understand the health risks of playa dust. They sent the samples to NIEHS-funded researchers at the University of Iowa's Environmental Health Sciences Research Center, who analyzed them for toxic chemicals and other contaminants. Because water from surrounding farms feeds into the Salton Sea, researchers are concerned the playa dust may contain pesticides and heavy metals. Previous research has found these contaminants in Salton Sea sediments, aquatic life, and water.
"The collaboration with researchers at the University of Iowa allowed us to quickly learn about the toxicity of playa dust and how it may contribute to airway inflammation based on their animal models," said Johnston. "Preliminary results suggest that playa dust may lead to adverse changes in the movement of immune cells into the lung immediately following exposure." The researchers are still determining whether these immune changes are associated with pesticides and metals in the dust.
The USC researchers also are using air monitors at three schools bordering the lake to assess air quality. "The goal is to see whether the dust looks different in different areas and ultimately to identify a ‘signature' of the dust coming from the Salton Sea," Farzan said in a Desert Sun article. "We want to know what's mobilized into the air and what people are breathing at the community level."
In November 2017, the California State Water Resources Control Board approved a 10-year plan to build thousands of acres of wetlands and ponds in Imperial Valley. The plan will help restore the Salton Sea and control playa dust. Ahead of the vote to approve the plan, Johnston presented preliminary study results to ensure decision-makers understood the potential health effects playa dust poses to Imperial Valley communities.
"It's really important to think about how we clean up the air in the region, both existing sources of pollution and then also making sure that the Salton Sea is not going to be an additional burden on the communities," Johnston said in the Desert Sun article. "Kids have a right to play outside, to breathe clean air, so we need to be thinking about strategies and policies to make that happen."

Childhood Exposure to Flame Retardant Chemicals Declines Following Phase-Out
Exposure to flame retardants once widely used in consumer products has been falling, according to a new study by researchers at the Columbia Center for Children's Environmental Health. Although the chemicals were present in all children tested, the researchers are the first to show that levels of polybrominated diphenyl ethers (PBDEs) measured in children significantly decreased over a 15-year period between 1998 and 2013.
According to the study authors, these findings show that among children in New York City, PBDE exposure has gone down since the phase-out from consumer products. "However, it's important to remain vigilant. Since the phase-out of PBDEs, we have begun to detect other flame-retardant chemicals in children, which are likely being used as replacements," said senior author Julie Herbstman, Ph.D., in a Columbia University news story.
The Center has previously linked exposure to PBDEs with attention problems and lower scores on tests of mental and psychomotor development in children.
Participate in Air Quality Awareness Week!
The 2018 Air Quality Awareness Week starts today, April 30, and runs through May 4. This year's theme is: "Air Quality Where You Are." The goal is to promote events that increase air quality awareness and inspire people to take steps, no matter how large or small, to reduce their contribution to air pollution. Use the hashtag #AQAW2018 to join the conversation!
Each day has a different focus:
- Monday, April 30 - AirNow - 20th Anniversary!
- Tuesday, May 1 - Health (also World Asthma Day)
- Wednesday, May 2 - Wildfires
- Thursday, May 3 - Citizen Science / Air Quality Sensors
- Friday, May 4 - Air Quality Around the World
American Lung Association Releases the 2018 State of the Air Report
More than four in ten Americans live in counties with unhealthy levels of either ozone or particle pollution, according to the 2018 State of the Air report from the American Lung Association. The report found that ozone pollution was significantly worse compared to the previous year, while particle pollution generally continued to improve in 2014-2016.
Each year, the American Lung Association analyzes data from official air quality monitors to compile its report. Visit the American Lung Association webpage for more information.
2018 National Health Security Preparedness Index Released
Just released, the 2018 National Health Security Preparedness Index finds that the U.S. is more prepared to face public health threats, such as disease outbreaks and natural disasters, than in previous years. According to the Index, the U.S. scored a 7.1 on a 10-point scale for preparedness – nearly a three percent improvement over the last year and nearly an 11 percent improvement since the Index began five years ago. Supported by the Robert Wood Johnson Foundation, the Index is a tool for identifying strengths and gaps in the protections needed to keep people safe and healthy in the face of large-scale public health threats.
Tools and resources are available that provide a comprehensive overview of Index findings, details about methods and data, and suggestions for how to use the Index to improve health security and preparedness in communities across the nation. Anna Goodman Hoover, Ph.D., who is part of the University of Kentucky's Superfund Research Program, serves as deputy director of the Index's program management office.
Nominate a Colleague for the JPB Environmental Health Fellows Program
The JPB Environmental Health Fellows Program is accepting nominations for fellowships to support early career scientists who are committed to health disparities research. With support from the JPB Foundation, the Program provides mentorship and funding up to $240,000 over the course of a two- to three-and-a-half-year period. Unlike in other fellowship programs, the JPB Environmental Health Fellows remain at their home institutions. The home institution must demonstrate its commitment to the Fellow by allowing release time from teaching and other activities and by providing additional support.
The Program was established to promote a new generation of environmental health scholars who are committed to comprehensive approaches in addressing health disparities in disadvantaged communities. JPB Environmental Health Fellows will learn from scientific leaders about conducting rigorous research on social and environmental factors that contribute to health disparities. Fellows also will be trained in leadership and communication.
Submit a nomination by May 16.
