Study: Drilling into Critical Windows of Exposure: Trimester-Specific Associations between Gas Development and Preterm Birth

This article describes how fracking affects premature births. Several studies suggest that living near unconventional gas development during pregnancy may contribute to poor birth outcomes, including low birth weight,1,2 prematurity, 3,4 and some birth defects.5 The emissions and activities related to unconventional gas wells (i.e., those that use hydraulic fracturing to release gas from shale rock) vary at each phase of the site’s life. A new proximity study reported in Environmental Health Perspectives takes a first look at phase- and trimester-specific associations between unconventional gas activity and preterm birth.6
