Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. Their findings are published in the ACS journal Environmental Science & Technology. Automobile tire rubber in general consists of approximately 40?
