Since the rise in the use of hydraulic fracturing of shale to produce natural gas and oil, scientists, politicians, industrialists, and others have debated the merits and detractions of the practice. In a newly published paper in Toxicological Sciences, members of the Society of Toxicology (SOT), alongside other experts, outline how toxicological sciences can be used to determine what risks may or may not be associated with hydraulic fracturing.
"Toxicology is the study of the effects of chemical, physical, or biological agents on living organisms and the environment. As such, toxicologists should be at the forefront of discussions of hydraulic fracturing," says Society of Toxicology President Norbert E. Kaminski, PhD. "We can provide information on the potential toxicity of the chemical and physical agents associated with the process, individually and in combination."
In "The Role of Toxicological Science in Meeting the Challenges and Opportunities of Hydraulic Fracturing" Bernard D. Goldstein, et al, identify a series of potential pathways of contamination and toxicological effects associated with hydraulic fracturing that should and are being explored by researchers:
