When some 18 girls in the upstate New York town of Le Roy developed unexplained tics and twitches starting in August 2011, many were quick to suspect that the cause was toxic substances in the environment. There had been a major chemical spill there in 1970. Erin Brockovich, of movie fame, started an investigation (as did EPA). But many of the potential chemical causes were ultimately discounted. Later hypotheses about the cause included sociological, psychological, and infectious factors. Today, many of the victims are doing better.

"Every day, inspectors in white hats and coats take up positions at every one of the nation's slaughterhouses, eyeballing the hanging carcasses of cows and chickens as they shuttle past on elevated rails, looking for bruises, tumors and signs of contamination."

"Exposure to certain pollutants early in a rat’s pregnancy can foster disease in her offspring during their adulthood as well as in subsequent generations, a new study shows. A wide range of pollutants elicited such lasting effects, despite future generations never encountering the triggering pollutant."
