Coal Tar Guidance February 2018

50mg/kg (0.005%) concentration of BaP correlates to around 1000mg/kg (0.1%) coal tar. Thus, where BaP is less than 0.005%, the amount of coal tar is considered low enough for the material to be considered Non-Hazardous. Several factors control the chemistry of coal tar; therefore because of its variability no single test is

Coal Tar and Coal-Tar Pitch

Coal tar is derived from coal. It is a byproduct of the production of coke, a solid fuel that contains mostly carbon, and coal gas. Coal tar is used primarily for the production of refined chemicals and coal-tar products, such as creosote and coal-tar pitch. Certain preparations of coal tar have long been used to treat various skin conditions ...

Health Policy Brief: Coal Tar & Coal-Tar Pitch

Coal-tar pitch and coal tars are classified as Group 1 carcinogens, meaning they are confirmed carcinogenic to humans. The processes of coal-tar distillation, coke production, and coal gasification, as well as the occupation of "paving and roofing with coal-tar pitch," are also in this highest class of carcinogenicity.[12]
