MedicalResearch.com: What is the background for this study? What were some of the chemicals released by the coal-coking plant?
Response: Pittsburgh has a long history as the nation's principal source of bituminous coal production and home to iron and coke industries since the late 19th century, and is also known as one of the cities with the highest levels of air pollution and most air-pollution related deaths in the US, to date. The Shenango, Inc Coke Plant was one of the significant industrial emission sources in the area before its closure in January 2016.
Coal-coking plants like the Shenango plant utilizes a destructive heated distillation process called pyrolysis to volatilize and drive the impurities out of coal and produce coke, a purer product with higher carbon content for use in iron and steel production. From this process, coke plant operations are known to generate high emissions of complex air pollution mixtures into the ambient air, including particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), polycyclic organic matter (POMs), volatile compounds (VOCs), and volatilized trace metals such as arsenic, nickel, selenium, lead, and cobalt.
Our study examines the changes in respiratory health in the community residing near the Shenango Coke Plant before vs. after its closure, providing a direct quantification of the health benefits of such fossil-fuel-related air pollution reductions.
