这项研究利用了宾夕法尼亚州页岩气威尔斯井的引进，以应对围绕水力压裂钻井方法日益增长的争议。使用详细的位置数据的母亲的地址和地理信息系统坐标的气井威尔斯，这项研究审查了单胎分娩的母亲居住在附近的页岩气井从2003年至2010年在宾夕法尼亚州。与生活在未来油井2.5公里范围内的母亲相比，钻井的引入增加了生活在油井2.5公里范围内的母亲的平均低出生体重和降低了足月出生体重。使用小于胎龄儿和APGAR评分等指标也检测到了不良反应，但未发现对妊娠期的影响。这些结果与其他婴儿健康指标、规格和伪造试验的许多变化相比具有稳健性。在密集的边缘，一个额外的井与低出生体重增加7%，足月出生体重减少5克和早产增加3%相关。这些发现表明，页岩气开发对人类健康构成重大风险，并对页岩气开发的监管产生政策影响。
This research exploits the introduction of shale gas wells in Pennsylvania in response to growing controversy around the drilling method of hydraulic fracturing. Using de- tailed location data on maternal addresses and GIS coordinates of gas wells, this study examines singleton births to mothers residing close to a shale gas well from 2003–2010 in Pennsylvania. The introduction of drilling increased low birth weight and decreased term birth weight on average among mothers living within 2.5 km of a well compared to mothers living within 2.5 km of a future well. Adverse effects were also detected using measures such as small for gestational age and APGAR scores, while no effects on gestation periods were found. These results are robust to other measures of infant health, many changes in specification and falsification tests. In the intensive margin, an additional well is associated with a 7 percent increase in low birth weight, a 5 gram reduction in term birth weight and a 3 percent increase in premature birth. These findings suggest that shale gas development poses significant risks to human health and have policy implications for regulation of shale gas development.
