Coal tar and paving products.
Environ Health Perspect 2006 Apr; 114(4):A210
The National Institute for Occupational Safety and Health (NIOSH) has a partnership relationship with the asphalt paving and roofing industries and their associated unions. Our partners saw in the EHP Focus article "Paving Paradise: The Peril of Impervious Surfaces" (Frazer 2005) the statement on page A459: "Asphalt is one concern, as it contains coal tar pitch, a recognized human carcinogen . . . . " Our partners asked us if we could help them address this statement. By definition, asphalt is a petroleum product and contains no coal tar. However, some pavement-repair products and sealants may contain coal tar. NIOSH did not find any evidence of coal tar in U.S. asphalt in our hazard review Health Effects of Occupational Exposure to Asphalt (NIOSH 2000).
