milhayser | April 28, 2016Research makes it increasingly clear that along with drilling for oil and mining coal, extracting natural gas from deep underground causes serious damage to the environment and to public health. On The Pump Handle, Kim Krisberg examines the contamination that may result from dumping fracking wastewater into disposal wells, writing "about 1,000 different chemicals are used in the fracking industry, with more than 100 being known or suspected endocrine disruptors." Researchers collected water samples downstream from wells in West Virginia, and after "exposing both female and male mammalian sex…
cmonforton | December 12, 2012A recently published case-control study involving more than 2,100 women in southern Ontario, Canada reported a strong association between being employed in the automotive plastics industry and breast cancer. The researchers recruited the 'case' subjects between 2002-2008 among newly diagnosed breast cancer patients and the randomly-selected controls from the same geographic area.

Elevated odds of breast cancer were found among women…

An elegant but disturbing paper was just published that documents that biologically relevant concentrations of endocrine disrupting pollutants are affecting the quality and quantity of song produced by male songbirds, which in turn, influences female mate choice. According to the research team, not only do these pollutants influence behavior, but they also affect…
