Shale Gas Production in England – an updated public health assessment


Medact released in July 2016 an updated assessment of the potential health impacts of shale fracking in England.  This new report reaches broadly the same conclusions as our 2015 report Health and Fracking, however it is now supported by a much larger body of evidence published in the year since the first report was produced.  In the …

A risk assessment tool applied to the study of shale gas resources

mash up of a pic of the Zuma spill and a fracking risk formula

In this paper a new, versatile method for assessing the overall risk of hydraulic fracturing in shale is presented. The method is supposed to predict the probability of adverse events of the technique in a specific location and has been tested in a shale field in Asturias (Spain). Its authors propose the application of this …

Potential hazards of air pollutant emissions from UOG operations on the respiratory health of children and infants

Children are known to be at a greater risk from exposure to air pollutants, which can impair lung function and neurodevelopment, or exacerbate existing conditions, such as asthma, because the respiratory system is particularly vulnerable during development in utero, the postnatal period, and early childhood. Existing epidemiology studies document the impact of air pollutant exposure …

Toward an Understanding of the Environmental and Public Health Impacts of Unconventional Natural Gas Development

While research continues to lag behind the rapid scaling of UNGD, there has been a surge of peer-reviewed scientific papers published in the past several years. By the end of 2015, over 80% of the peer reviewed scientific literature on shale and tight gas development has been published since January 1, 2013 and over 60% …

Endocrine disrupting activities of surface water associated with an oil and gas industry wastewater disposal site

Because of key data gaps that exist in understanding the potential impact of underground injection of hydraulic fracturing wastewater on surface water quality and environmental health the goal of this study was to assess endocrine disrupting activity in surface water at a West Virginia injection well disposal site. Compared to reference water extracts upstream and …

Chronic Oral Toxicity Values for Chemicals Present in Hydraulic Fracturing Fluids, Flowback and Produced Waters

Concerns have been raised about potential public health effects that may arise if hydraulic fracturing-related chemicals were to impact drinking water resources. This study presents an overview of the chronic oral toxicity values—specifically, chronic oral reference values (RfVs) for noncancer effects, and oral slope factors (OSFs) for cancer—that are available for a list of 1,173 …

Quantitative Survey and Structural Classification of Hydraulic Fracturing Chemicals Reported in Unconventional Gas Production

Of over 1000 reported hydraulic fracturing (HF) additives in unconventional gas exploitation, the physicochemical properties relevant for environmental fate, toxicity and chemical analysis were classified. Key findings: While many substances were nontoxic, frequent disclosures also included notorious groundwater contaminants like petroleum hydrocarbons (solvents), precursors of endocrine disruptors like nonylphenols (nonemulsifiers), toxic propargyl alcohol (corrosion inhibitor), …
