Fracked ecology: Response of aquatic trophic structure and mercury biomagnification dynamics in the Marcellus Shale Formation

The results of this study suggest fracking has the potential to alter aquatic biodiversity and methyl mercury concentrations at the base of food webs. Abstract Unconventional natural gas development and hydraulic fracturing practices (fracking) are increasing worldwide due to global energy demands. Research has only recently begun to assess fracking impacts to surrounding environments, and …

Exposure to Glycol Ethers and Neurocognitive Abilities in 6-Year-Old Children: The PELAGIE Cohort Study

Glycol ethers are organic solvents which are widely used in cosmetics and cleaning agents, but also – in huge quantities – for drilling and for hydraulic fracturing. The results of this investigation suggest that prenatal exposure to glycol ethers can affect neurodevelopment, particularly the development of cognitive abilities in young people. Abstract Background: Glycol ethers …

Identifying chemicals of concern in hydraulic fracturing fluids used for oil production

Based on an analysis of quantities used, toxicity, and lack of adequate hazard evaluation, QACs, biocides, and corrosion inhibitors were identified as priority chemicals of concern that deserve further investigation. Abstract Chemical additives used for hydraulic fracturing and matrix acidizing of oil reservoirs were reviewed and priority chemicals of concern needing further environmental risk assessment, …

Inspiring Collaboration: The Legacy of Theo Colborn’s Transdisciplinary Research on Fracking

This article describes Dr Theo Colborn’s legacy of inspiring complementary and synergistic environmental health research and advocacy. Colborn, a founder of endocrine disruption research, also stimulated study of hydraulic fracturing (fracking). In 2014, the United States led the world in oil and gas production, with fifteen million Americans living within one mile of an oil …

Quantity of flowback and produced waters from unconventional oil and gas exploration

Key findings: Estimated flowback and produced water volume from unconventional oil and gas wells is 1.7 to 14.3 million liters per well. Only a small fraction (4-8%) of the flowback and produced waters is composed of returned injected hydraulic fracturing fluids. The majority (92-96%) of flowback and produced waters is composed of naturally occurring formation …

Adverse Reproductive and Developmental Health Outcomes Following Prenatal Exposure to a Hydraulic Fracturing Chemical Mixture in Mice

white lab mice

The authors of this study have previously shown that 23 of 24 commonly used hydraulic fracturing chemicals can activate or inhibit the estrogen, androgen, glucocorticoid, progesterone, and/or thyroid receptors in a human endometrial cancer cell reporter gene assay and that mixtures can behave synergistically, additively, or antagonistically on these receptors. Their study results suggest potential …

The association between oil and natural gas extraction processes and human reproduction

This review of the current literature makes clear: The impact of unconventional oil and gas activities may be greater than that of conventional activity, given that unconventional activities employ many of the same approaches and use dozens of known endocrine-disrupting chemicals in hydraulic fracturing. Abstract: This systematic review identified 45 original published research articles related …
