Humans may be harmed by endocrine disrupting chemicals released during natural gas mining

More than 15 million Americans live within one mile of unconventional oil and gas (UOG) operations that combine directional drilling and hydraulic fracturing, or 'fracking,' to release natural gas from underground rock. Researchers have reviewed research on health effects associated with UOG operations and concluded these activities have potential for environmental release of a complex mixture of endocrine disrupting chemicals that could potentially harm human development.
