SRP Researcher Weighs in on Trendy Hair Treatment

Martyn Smith
SRP researcher Martyn Smith commented on the effects of the trendy Brazilian Blowout treatment: "If [salon workers] are getting that high a dose that it's causing effects, that's pretty serious."

UC-Berkeley SRP Program Director Martyn Smith provided comments for a recent Los Angeles Times story about the safety of Brazilian Blowouts, a trendy hair treatment gaining popularity in cities across the country. A proprietary chemical solution used in the treatment is the target of investigation by Occupational Health and Safety departments, which claim that it contains high levels of formaldehyde.

The treatment involves the application of the solution in question to damp, clean hair. The hair is then dried and the process finished with a flat-iron heated to 450 degrees F. Laboratory tests show that the solution contains between 6.3% and 10.6% formaldehyde, up to 100 times the U.S. Occupational Health and Safety Administration's 0.1% "safe" limit. In addition, the bottles containing the solution is marked "formaldehyde free" and "salon safe", leading to claims of false advertising on the part of the manufacturer. The manufacturer contests the veracity of these claims and maintains that the product is safe and correctly labeled.

The treatment is illegal in Europe and Australia, and was banned in Canada in October. Rep. Earl Blumenauer (D-Ore.), who spoke at this year's Annual Meeting, has asked the Food and Drug Administration and the Federal Trade Commission to investigate the matter in this country.

UCSD Researcher Michael Karin Receives Harvey Prize

Michael Karin, University of California-San Diego (UCSD) SRP, has been awarded the 2010 Harvey Prize in human health by the Technion, Israel's premier institute of technology.

The prize honors Karin's seminal research linking obesity, environmental toxicant exposure, inflammation and cancer. Specifically, judges noted Karin s "pioneering contributions" to the deciphering of the molecular mechanism used by mammalian cells to react to cytokines (proteins that cause inflammation), to adverse environmental conditions and to various pathogens. "These discoveries," the judges said, have "led to the identification of new target proteins that have recently been used to develop new medications for preventing and treating various malignant tumors."

The Harvey Prize has been awarded annually since 1972 to recipients in human health, science and technology, and for contributions to peace in the Middle East. It is named after Leo M. Harvey, an American industrialist who established the prize fund. To date, 13 Harvey Prize recipients have gone on to win a Nobel Prize.

As part of the scientific response to the Deepwater Horizon oil spill in the Gulf of Mexico, Dr. Kim Anderson of the Oregon State University (OSU) Superfund Research Program (SRP) is sampling polycyclic aromatic hydrocarbons (PAHs) in the air and water in the Gulf of Mexico. She is using passive sampler devices (PSDs) in the Gulf to determine the bioavailable fraction of the contaminants before, during, and after the spill. Results of this sampling campaign will be used to link environmental exposures to biological responses in the environment and reduce uncertainties found in risk assessments of these disasters.

As an addition to their monitoring project, OSU has produced a short film that introduces their work. The film shows the research team deploying the sampling devices at four field sites in the Gulf of Mexico. You can view the film at the OSU webpage .

Columbia University SRP Shows Arsenic Exposure Increases Risk of Death

According to a new study, 35-77 million Bangladeshis may face a higher risk of death from chronic exposure to arsenic in their drinking water. The Columbia University SRP, led by Habibul Ahsan, published this finding June 19 online in The Lancet . They report that in their six-year cohort study, nearly 21 percent of deaths from all causes and 24 percent of deaths linked to chronic disease could be attributed in part to drinking arsenic-contaminated water.

The drinking water contamination problem began in Bangladesh in the 1970's, when aid organizations dug millions of hand-pump wells in an effort to provide clean, pathogen-free drinking water to the residents. What they didn't know at the time is that the water was contaminated with elevated levels of naturally-occurring arsenic (see BBC story .) According to UNICEF (351KB) , the arsenic wasn't detected until the early 1990's. The World Health Organization calls this situation "the largest mass poisoning of a population in history."

In addition to its successful efforts to raise awareness of arsenic exposure in the region, Columbia University has also made great strides in reducing arsenic exposure in their study population. In a talk last year at Duke University, Joseph Graziano described some of the program's remediation efforts in the region. Also, the cohort has recently been expanded from 12,000 to 20,000 for examining rarer health outcomes. Finally, one of Dr. Ahsan's newly established projects is to evaluate nutritional interventions to minimize health impacts of arsenic.

NIEHS Director References SRP Research in Congressional Testimony

NIEHS Director Dr. Linda Birnbaum acknowledged the research being done at the Dartmouth Superfund Research Program in a testimony to Congress last month. The testimony, delivered to the House of Representatives Committee on Energy and Commerce, was to educate committee members about the research NIEHS is doing to learn about endocrine-disrupting chemicals in drinking water and the risks they pose to human health and the environment.

Birnbaum had this to say about Dartmouth's research: "An NIEHS-funded group at the Dartmouth College Superfund Research Program discovered that arsenic can act as a potent endocrine disruptor. They have shown that arsenic profoundly affects the function of five steroid hormone receptors, as well as the function of related nuclear receptors for thyroid hormone and retinoic acid...They have also shown that arsenic has a significant effect on the ability of an activated hormone receptor to regulate gene expression, and that low level drinking water arsenic has strong, tissue-specific effects on expression of genes and proteins involved in the innate immune response in mouse lung. They found that mice that were exposed to 100 ppb arsenic in drinking water had a significantly compromised response to H1N1 influenza infection."

Dartmouth Film Shows Risks of Arsenic in Drinking Water, Outlines Simple Solutions

The Dartmouth SRP Research Translation Core (RTC) premiered their film, "In Small Doses: Arsenic", to an audience of 40 stakeholders, including industry officials and state legislators, on February 11 in Concord, N.H. The film seeks to encourage owners of private wells to check the levels of arsenic in their drinking water.

Approximately 40% of the state is serviced by private wells, which are not subject to mandatory arsenic tests. At the time of the screening, a bill was under consideration that would make well testing mandatory throughout the state. Though the bill did not pass through committee, those in attendance were energized and dedicated to working with state legislators to enact testing laws.

"We have been working with our state and regional partners on this issue for more than a decade,"; says Bruce Stanton, Ph.D., Program Director of the Dartmouth SRP. "We are all concerned that it's 2010 and still most private well owners are not testing, in spite of concrete evidence that wells in New Hampshire contain potentially high and harmful levels of arsenic if ingested over long periods of time."

Tackling Triclosan: Congressman Calls for Review

Rep. Edward Markey (D-MA) is calling on the EPA to consider more stringent regulations on triclosan (TCS) and triclocarban (TCC), antimicrobial ingredients found in myriad personal care and cleaning products. The latest research, including work from the University of California-Davis SRP and University of Arizona SRP, has demonstrated the chemicals' biopersistance and bioaccumulation in aquatic species, and indicates that TCC and TCS may also indirectly act as endocrine disruptors and carcinogens.

Last year, the agency generally approved uses of TCC and TCS under pesticide law, but Markey advocates that there may be a "strong basis" justifying testing and regulation under the Safe Drinking Water Act. Most uses of the chemicals were re-approved in a 2008 review. However, due to the significant research and available data, the next review of the chemicals will be held in 2013, a full ten years ahead of schedule.

Concern Over Canal Mud as Dredge Plan Nears

The town of East Chicago, IN has a legacy of polychlorinated biphenyl (PCB) contamination due to its history of intense industrial and shipping activities. A team of researchers led by Dr. Keri Hornbuckle, from the University of Iowa SRP, sampled soil in and around the Indiana Harbor and Ship Canal to determine the level of PCB contamination. The study found that sediment in the area is so contaminated with the cancer-causing industrial pollutant that it could rank among the most contaminated sites in the nation, requiring extensive cleanup.

However, The Army Corps of Engineers plans to dredge the canal starting in late 2011 to facilitate ship traffic. Hornbuckle and her team are interested in any unintended effects the dredging might cause. Neither the researchers nor the Army Corps of Engineers know how deep the PCBs go. Dredging could remove a lot of the contaminated sediment, but it might also stir up the PCBs and enlarge the contamination area. The dredging is expected to take seven to 10 years and take out about 1.6 million cubic yards of sediment.
