Featured Research Reviews

Here at EHP we know that it can be tough to get your hands on peer-reviewed literature and even tougher to understand the scientific jargon within it. We also know that information is power! Featured Research Reviews will feature summaries of recent and relevant studies clarifying the impact that shale gas development has on health.

Willis et al. (2021): Proximity to oil and gas drilling and birth outcomes

A collaboration of researchers from Oregon State University and the University of Rochester worked together to examine the effect of living within proximity to oil and gas drilling sites and its potential effect on the birth weight of newborns in Texas. Texas generates roughly 24% of U.S. natural gas, and between 1985 and 2019 there were a total of 356,527 drilling sites within that state.

Denham et al. (2021): Acute myocardial infarction (heart attack) associated with unconventional natural gas development

Acute myocardial infarction (AMI), commonly referred to as a heart attack, is one of the leading causes of morbidity and mortality in the United States and around the world. A result of coronary artery disease, AMI is associated with a number of well-known risk factors, including exposure to air pollution—especially from fine and ultrafine particulate matter, volatile organic compounds (VOCs), and ground-level ozone.

Hendryx et al. (2020): Natural gas compressor station emissions and mortality rates

Researchers from Indiana University examined the impact of natural gas compressor station emissions on human health by testing for associations, over one year, between volatile organic compound (VOC) emissions from major (Title V) compressor stations and mortality rates adjusted for age in the U.S. population. Compressor stations... Read More

McAlexander et al. (2020): Unconventional natural gas development and hospitalization for heart failure in Pennsylvania

There have been a number of important studies related to unconventional oil and gas development (UOGD) conducted by Dr. Brian Schwartz and his colleagues at the Johns Hopkins School of Public Health, using data from Geisinger, a large health care system in Pennsylvania. The most recent, Unconventional Natural Gas Development and Hospitalization for Heart Failure in Pennsylvania, was published in... Read More

Cushing et al. (2020): Flaring events and birth outcomes

A research team from UCLA and USC took a novel approach to examining the relationship between poor birth outcomes and shale gas development in south Texas by specifically considering proximity to flaring events, not simply proximity to existing and active shale gas infrastructure. Flaring is a procedure used by the fossil fuel industry to burn off excess natural gas during drilling, producing, and transporting oil and gas. Flaring events release numerous hazardous air pollutants, including... Read More

Denham et al. (2019): Hospitalizations for skin issues and genital/urinary issues

Utilizing Pennsylvania county-level hospitalization data and state unconventional natural gas well data, researchers from the University of Rochester found a positive association between the number of gas wells per square kilometer and hospitalizations within two health categories: genital and urinary issues, including kidney stones, urinary tract infections, and kidney infections, and also skin issues, such as cellulitis and abscesses. Over time, as the number of unconventional wells... Read More

Tustin et al. (2017): Sinus problems, migraines, and fatigue

Researchers from Johns Hopkins Bloomberg School of Public Health studied primary care patients at the Geisinger Clinic via questionnaire to survey nasal and sinus, migraine, and fatigue symptoms in Pennsylvania patients. Geisinger clinics are located throughout central and northern Pennsylvania, both in areas of heavy unconventional natural gas development (UNGD) and areas with none. They discovered that patients who lived in areas with the most UNGD activity (in this case exposure was... Read More

McKenzie et al. (2017): Childhood cancer incidence

Lisa McKenzie, a researcher at the University of Colorado, and her team have conducted several important studies on the associations between exposure to shale oil and gas development and health. In this study, she and colleagues look at the two most common forms of childhood cancer – acute lymphocytic leukemia (ALL) and non-Hodgkin lymphoma (NHL) – and their association with exposure to shale well pads. Existing research has already shown that exhaust fumes, PAHs, and other chemicals,... Read More

Rasmussen et al. (2016): Asthma exacerbations

Researchers at Johns Hopkins Bloomberg School of Public Health studied the potential impact of shale gas development on asthma exacerbations between 2005 and 2012. Asthma exacerbations are characterized by shortness of breath, wheezing, coughing, and/or chest tightness resulting from inflammation that restricts air flow to and from an individual’s lungs. Researchers looked at the records of 35,508 Geisinger Health System asthma patients who needed medical treatment for an exacerbation... Read More

Stacy et al. (2015): Birth weight and small for gestational age

Researchers out of the University of Pittsburgh School of Public Health released a study investigating the relationship between living in an area with heavy unconventional natural gas development and birth outcomes.  They utilized data collected by the Pennsylvania Department of Health on 15,451 live births that occurred in Washington, Westmoreland, and Butler (southwest Pennsylvania) counties between 2007 and 2010. They found that the most exposed mothers, in this case those with more gas...
