Exposure Assessment of Polycyclic Aromatic Hydrocarbons in Refined Coal Tar Sealant Applications
Coal tar sealants are applied as a protective coating for paved surfaces. Many polycyclic aromatic hydrocarbons (PAHs) are found in these sealants. Several of these PAHs are known or suspected to cause, or increase the risk of developing cancer, but to date there has been no published research on workplace exposures to coal-tar-based sealant.
