Taking their cue from the anti-nuclear energy movement (which has been wildly successful at scaring the entire world) anti-frackers are using the "C" word....cancer. Fortunately and typically,
The Colorado School of Public Health (CSPH) at the University of Colorado recently announced an article that will be published this month in the journal Science of the Total Environment. The article is based on a study of air pollution resulting from oil and gas development (including hydraulic fracturing or “fracking”) in Garfield County. According to the announcement, the article will reveal findings of benzene and other “potentially toxic petroleum hydrocarbons” at concentrations potentially hazardous to human health. But before this study, or any similar study, can be taken as a basis for alarm, several questions need to be answered: What are these “potentially toxic” chemicals? Where do they come from? And how dangerous are they really?
To answer these questions, it will be helpful to focus on just one chemical: in this case, benzene—the chemical most often associated oil and gas development. Focusing on benzene will also be helpful in evaluating the CSPH study, because, according to the announcement, benzene was the “the major contributor to lifetime excess cancer risk” found in the study.
