Most of us are familiar with the odor and deep black appearance of freshly sealcoated asphalt. Sealcoats are used to improve the appearance and prolong the life of driveways and parking lots.

Some sealcoat products contain coal tar (a byproduct of coke manufacturing)—a health and environmental hazard.

A series of fact sheets produced by the UW-Extension Solid and Hazardous Waste Education Center discusses the toxicity, health and environmental hazards of coal tar and suggests ways to reduce risk.

Topics covered by the fact sheets include:
