When writer Florence Williams was nursing her second child, she read a research study about toxins found in human breast milk. She decided to test her own breast milk and shipped a sample to a lab in Germany.
What came back surprised her.
Trace amounts of pesticides, dioxin and a jet fuel ingredient — as well as high to average levels of flame retardants — were all found in her breast milk. How could something like this happen?
A proposed study of people in northern Pennsylvania could help resolve a national debate about whether the natural gas boom is making people sick.
The study would look at detailed health histories on hundreds of thousands of people who live near the Marcellus Shale, a rock formation in which energy companies have already drilled about 5,000 natural gas wells.
If the study goes forward, it would be the first large-scale, scientifically rigorous assessment of the health effects of gas production.
