Urban Parks Built on Former Waste Incineration Sites Could Be Lead Hotspots
Decades after many North American cities shut down their municipal waste incinerators due to pollution concerns, a Duke University study warns of potential lead contamination in urban soils. Led by Professor Daniel D. Richter, the research identified significantly elevated levels of lead in certain Durham, N.C. parks built on former incinerator sites, with some concentrations exceeding five times the EPA’s safety standards for children's play areas. Such exposure poses long-term health risks, especially for children. The team's findings, based on historical waste management surveys, indicate that around half of all cities in the U.S. and Canada used incineration between the 1930s and 1950s, showcasing the need for nationwide soil monitoring and hotspot identification.
