Endocrine Disrupters

Lead isn’t the only toxin threatening the safety of community drinking water. A recent study on water located downstream from a West Virginia fracking disposal site uncovered levels of endocrine-disrupting chemicals high enough to adversely impact the aquatic animals living there. And that means human health could be at risk too. “We can’t make any direct (human health) assumptions about this particular water,” said study co-author Susan Nagel, an associate professor in the University of Missouri School of Medicine’s Division of Obstetrics, Gynecology and Women’s Health. “But we certainly…

Manufacturers who market their products as “BPA-free” aren’t just sending consumers a message about chemical composition. The underlying message is about safety — as in, this product is safe or least more safe than products that do contain BPA. However earlier this month, another study found that a common BPA alternative — BPS — may not be safer at all. “BPS works very similarly to BPA,” said Nancy Wayne, a reproductive endocrinologist and professor of physiology at the University of California-Los Angeles David Geffen School of Medicine. “We’re not the first to show this, but what’s captured…

My public health colleague, Adam Finkel, ScD, MPP, received this month the 2013 Alumni Leadership award from the Harvard School of Public Health (HSPH), as part of the school’s 100th birthday celebration. Finkel and I were co-workers in the mid-1990’s at the Occupational Safety and Health Administration, where he was the Director of the Office of Health Standards. I learned more from him about risk analysis and risk assessment than in any semester–long course. Why? Because agency risk assessments are not academic exercises when they are used to inform regulatory decisions. Finkel touched on…

Maybe people aren't listening when scientists talk about how Bisphenol A, a chemical used in plastics, is a pseudo-estrogen. Maybe others think that there are no side effects to flushing their extra or expired birth control down the toilet. Whoever is to blame, one thing is for certain: the male gender is threatened, and gravely. A new report released today by CHEMtrust is the most comprehensive review to date of gender-bending chemicals and their effects on males of all species, from road kill to humans, drawn from over 250 studies worldwide - and it doesn't have good news. Still not…
