Abstract

The rapid growth of unconventional natural gas development (UNGD), also known as hydraulic fracturing, has raised concerns of potential exposures to hazardous chemicals. Few studies have examined the risk of childhood cancer from exposure to UNGD. A case-control study included 498 children diagnosed with leukemia, lymphoma, central nervous system neoplasms, and malignant bone tumors during the period 2010-2019 identified through the Pennsylvania Cancer Registry. Cases were matched to controls using Pennsylvania birth records. For each subject, a new overall UNGD exposure metric was calculated which incorporates both spatial (proximity) and temporal (duration) aspects of well activity. Conditional logistic regression models were used to estimate the risk of combined and individual cancers by overall UNGD exposure, and well proximity. Children with a higher overall UNGD exposure (3rd/4th quartiles) had an increased risk for the four malignancies combined [OR] 1.69 (95% CI 1.01, 2.82) and 1.79 (95% CI 1.00, 3.19) compared to non-exposed children. Overall, individuals living within 0.5 miles of a UNGD site were 3.94 times (95% CI 1.66, 9.30) more likely to develop a malignancy compared to non-exposed children and the risk of lymphoma within 0.5 miles and 0.5-1 miles was also elevated [ORs of 5.05 (95% CI 1.09, 23.39) and 7.71 (95% CI 1.01, 59.00), respectively] compared to non-exposed. Our study found that overall UNGD cumulative activity as well as a proximity to UNGD wells were associated with an increased risk of childhood lymphoma and overall childhood cancers combined.

期刊介绍: International Journal of Environmental Research and Public Health (IJERPH) (ISSN 1660-4601) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes, and short communications in the interdisciplinary area of environmental health sciences and public health. It links several scientific disciplines including biology, biochemistry, biotechnology, cellular and molecular biology, chemistry, computer science, ecology, engineering, epidemiology, genetics, immunology, microbiology, oncology, pathology, pharmacology, and toxicology, in an integrated fashion, to address critical issues related to environmental quality and public health. Therefore, IJERPH focuses on the publication of scientific and technical information on the impacts of natural phenomena and anthropogenic factors on the quality of our environment, the interrelationships between environmental health and the quality of life, as well as the socio-cultural, political, economic, and legal considerations related to environmental stewardship and public health. The 2018 IJERPH Outstanding Reviewer Award has been launched! This award acknowledge those who have generously dedicated their time to review manuscripts submitted to IJERPH.
