lifetime health risks from early exposure

"“Our results show that the non-cancer health impacts from air emissions due to natural gas development is greater for residents living closer to wells,” the report said. “The greatest health impact corresponds to the relatively short-term, but high emission, well completion period.”  That’s due to exposure to trimethylbenzenes, aliaphatic hydrocarbons, and xylenes, all of which have neurological and/or respiratory effects, the study said. Those effects could include eye irritation, headaches, sore throat and difficulty breathing.
 
“We also calculated higher cancer risks for residents living nearer to the wells as compared to those residing further [away],” the report said. “Benzene is the major contributor to lifetime excess cancer risk from both scenarios.”  The report, which looked at those living about a half-mile from the wells, comes in response to the rapid expansion of natural gas development in rural Garfield County, in western Colorado."
