ABSTRACT The technology to recover natural gas depends on undisclosed types and amounts of toxic chemicals. A list of 944 products containing 632 chemicals used during natural gas operations was compiled. Literature searches were conducted to determine potential health effects of the 353 chemicals identified by Chemical Abstract Service (CAS) numbers. More than 75% of the chemicals could affect the skin, eyes, and other sensory organs, and the respiratory and gastrointestinal systems… 

Hydraulic fracturing for natural gas: impact on health and environment

Hydrofracturing for natural gas has significant economic benefits, and while natural gas is theoretically a better fossil fuel as compared to coal and oil, current fracking practices pose significant adverse health effects to workers and near-by residents.

Developmental and reproductive effects of chemicals associated with unconventional oil and natural gas operations

The scientific literature is reviewed providing evidence that adult and early life exposure to chemicals associated with UOG operations can result in adverse reproductive health and developmental effects in humans, and there is a compelling need to increase knowledge of the potential health consequences for adults, infants, and children from these chemicals.

Endocrine-Disrupting Chemicals and Oil and Natural Gas Operations: Potential Environmental Contamination and Recommendations to Assess Complex Environmental Mixtures

A need for an endocrine-centric component for overall health assessments is described and information supporting the idea that using such a component will help explain reported adverse health trends as well as help develop recommendations for environmental impact assessments and monitoring programs is provided.

A systematic evaluation of chemicals in hydraulic-fracturing fluids and wastewater for reproductive and developmental toxicity

A systematic screening approach identified 67 hydraulic fracturing-related candidate analytes based on known or suspected toxicity and incorporated data on potency, physicochemical properties, and environmental concentrations to further prioritize these substances for future drinking water exposure assessments or reproductive and developmental health studies.

Toxicological and chemical studies of wastewater from hydraulic fracture and conventional shale gas wells

In acute cytotoxicity and wound healing assays, there was dose‐dependent toxicity in human and rat cells with growth promotion at low concentrations, and a KCl sample of matched ionic strength showed a different toxicity profile from produced waters, indicating that salts alone were not the cause of toxicity.

Understanding exposure from natural gas drilling puts current air standards to the test

Current methods of collecting emissions data, as well as the analyses of these data, are not sufficient for accurately assessing risks to individuals or protecting the health of those near UNGD sites, and new protocols are needed.

Environmental and health impacts of ‘fracking’: why epidemiological studies are necessary

One of the most critical issues is the management of water produced in the gas or oil extraction process, which contains thousands of gallons of toxic chemicals, the vast majority of which are not identified.



Emergency Admissions for Cardiovascular and Respiratory Diseases and the Chemical Composition of Fine Particle Air Pollution

Ambient levels of EC and OCM, which are generated primarily from vehicle emissions, diesel, and wood burning, were associated with the largest risks of emergency hospitalization across the major chemical constituents of PM2.5.

The ozone component of global change: potential effects on agricultural and horticultural plant yield, product quality and interactions with invasive species.

It is concluded that current and projected levels of O3 in many regions worldwide are toxic to sensitive plants of agricultural and horticultural significance, while reductions in O3 precursor emissions will likely benefit world food production and reduce atmospheric concentrations of an important greenhouse gas.

Quantifying plant response to ozone: a unifying theory.

Among species, differences in ozone uptake and response can be predicted from differences in the inherent leaf diffusive conductance, and for an equivalent dose within a single growing season, agricultural crops are the most sensitive to ozone.

Low-Level Ozone Exposure and Respiratory Symptoms in Infants

At levels of ozone exposure near or below current U.S. EPA standards, infants are at increased risk of respiratory symptoms, particularly infants whose mothers have physician-diagnosed asthma.

Chronic Exposure to Ambient Ozone and Lung Function in Young Adults

A history of increased level of lifetime exposure to ambient O3 is associated with decreased function of airways in which O3 deposition in the lungs is the greatest, and adolescents with intrinsically smaller airways appear to be at greatest risk.

Relationship between air pollution, lung function and asthma in adolescents

Exposure to high levels of PM2.5 attenuates the protective effect of better lung function against new onset asthma, which was reduced in children exposed to higher levels of particulate matter with an aerodynamic diameter <2.
