Earlier this week, we cast this IOM study as offering little new news. But, as Julia Brody of The Silent Spring Institute points out, that’s not quite true. From the environmental Health News website:
…(M)ost of the news media missed the significance of the assessment on environmental chemicals. The real news is that the report is an authoritative statement that a cascade of scientific evidence plausibly links consumer product chemicals and pollutants with biological activity suggesting breast cancer risk.
Instead of saying what is in the report, glass-empty stories said that the IOM “failed” to “definitely” link any chemicals to breast cancer or find “clear” environmental links. Some incorrectly said the report tells women to stop worrying about consumer product risks. These stories ignore the report’s important explanation that definitive evidence is not attainable and lack of human evidence of harm doesn’t mean something is safe.
From original NYTimes story on the report:
The report, 364 pages long and two years in the making, was issued on Wednesday by the Institute of Medicine, an independent group that is part of the National Academy of Sciences and advises the government and public. The work was done by a committee of 15 outside experts, mostly from universities, and nine institute staff members. The sole sponsor was a breast cancer advocacy group, Susan G. Komen for the Cure, which requested the report and spent $1 million on it.
For women who were hoping for definitive safety information about the huge number of chemicals to which people are exposed — from air pollution and cosmetics to cleaning products, food and drinking water — the report may come as a disappointment. It is based largely on a review of existing research, and its limited advice reflects the lack of solid scientific information in many areas of concern to the public.
Women should take note on Cape Cod, where the breast cancer rate is higher than average. The Silent Spring Institute, one of the few groups doing research on environmental links to breast cancer, recently reporting finding 27 chemicals in well water on the Cape.
The 27 contaminants detected included 12 pharmaceuticals (the most common being one antibiotic and one epilepsy drug); five perfluorinated chemicals (found in non-stick and stain-resistant household products); four flame retardants; two hormones; one skin care product; one artificial sweetener; one insect repellent; and one plastics additive. Health-based guideline values were available for only four detected chemicals (PFOS, PFBS, DEET, carbamazepine), and no samples approached or exceeded these values. The most frequently detected chemical was acesulfame, an artificial sweetener, which was found in 85 percent of wells, and perfluorinated chemicals were detected in 70 percent of wells.
“While the levels of pharmaceuticals, flame retardants, and other emerging contaminants in drinking water are not currently regulated, we still think that it is prudent to find ways to prevent discharges from septic systems and wastewater treatment plants from impacting drinking water supplies, as we don’t fully understand the potential health impacts,” lead investigator Laurel Schaider said.
