Air Quality Near Fracking Sites A Concern For Human Health

Hydraulic fracturing (fracking) is a drilling technology used to collect trapped reserves of natural gas. This method does act as an alternative to dirtier coal energy; however, the human health impacts of fracking are a concern. While many communities in close proximity to fracking sites have voiced concern over water quality, the topic of air quality has been largely ignored.

The journal Environmental Health published a study called Air concentrations of volatile compounds near oil and gas production: a community-based exploratory study in which the levels of certain compounds were measured near fracking sites. The air sampling method was designed in a way that would provide accurate readings of public exposure near fracking sites with a resolution in the part-per-billion range. Air samples were analyzed for 75 VOCs, 20 sulfur compounds, and formaldehyde. Eight different chemicals showed levels exceeding federal guidelines under several operational circumstances. The most common chemicals that showed levels of concern were: benzene, formaldehyde, and hydrogen sulfide. Benzene and formaldehyde are known and suspected human carcinogens, respectably, and hydrogen sulfide poses as an acute health hazard. This study is important because it took the time to investigate an overlooked aspect of fracking that has a serious potential to cause harm to the neighboring population.



The news articles comes from The Telegraph, a newspaper from the United Kingdom. The article title reads, Fracking emits more formaldehyde than medical students experience from dead bodies. The article does not spend much time describing the research of the study being reported. It only quotes two sentences from the results section of the paper. Instead, The Telegraph article focuses on the chemicals and draws comparisons with which the readers can relate. In addition to the formaldehyde levels being “twice as high as medical students experience when dissecting dead bodies,” benzene levels were reported as “33 times the concentration that drivers can smell when filling up with fuel at a petrol station,” and hydrogen sulfide levels were “up to 60,000 times the acceptable odour threshold.” From that point, the article discusses the potential of fracking in Britain. The article presents both sides of the fracking argument, but seems to mostly quote potential fracking practices that will ensure safety.

I think that the study was well executed and necessary for assuring proper practices in future fracking operations. The effect of fracking on air quality in terms of human health should not be ignored. Hopefully, more stringent regulations will pass to ensure safer operations. The Telegraph article was an interesting change of pace from the Science Daily articles we usually find on our blog. I thought that The Telegraph used the study as an eye-catcher to introduce readers to the topic of fracking. Interestingly, the chemical comparisons used in the article were mentioned nowhere is the study. I would be very much like to see the source or calculations behind those descriptions. The news article appeared to use the study to detail the wrong way to frack. It seemed to me as though the writer was either neutral or they favored fracking in the UK, but under the stricter regulations listed by UK specialist in the article. I really liked how the article used the study to present a national issue, but the way it did so was sub-par. It didn't even provide any sort of link to the source material! I would rate the news article 4 out of 10.
