Coal tar is a byproduct of processing coal to make coke (a fuel with few impurities and a high carbon content) and contains cancer-causing polycyclic aromatic hydrocarbons (PAHs). Pavement sealants made from coal tar are much more toxic than asphalt, putting families at higher risk of cancers including lung cancer.
PAHs in coal tar sealant attach to dust created by tire friction and are tracked into homes on shoes, carried on clothing and drift in through open windows. Because of the PAHs’ proximity to floors and carpet, babies and young children are at particular risk of exposure of these lung-cancer causing carcinogens.
