GLRPPR Sector Resource: PAHs and Coal-Tar-Based Pavement Sealcoat
PAHs and Coal-Tar-Based Pavement Sealcoat
Sealcoat contributes PAHs to many different parts of our environment. PAHs are released from sealcoated pavement into the air. Dried sealcoat is abraded from pavement by vehicle tires and snow plows into fine dust containing high concentrations of PAHs. The dust can wash off in stormwater runoff and be carried to stormwater ponds, streams, and lakes. It can be blown onto adjacent pavement or soils, or be tracked into homes. Living adjacent to coal-tar-sealed pavement is associated with a significantly increased risk of cancer.
