Basketball court with coal-tar-based sealcoat

Coal-tar sealcoated basketball court

Detailed Description

Coal-tar-based pavement sealcoat, used here on a basketball court, is a potent source of polycyclic aromatic hydrocarbons (PAHs) to the environment.  Coal-tar-based sealcoat products typically are 20-35% coal-tar pitch, a known human carcinogen.  PAH-rich sealcoat particles can be tracked indoor, where they become incorporated into house dust.  Find USGS research on PAHs and coal-tar sealcoat here.
