Notes:
Chrysene is a polynuclear aromatic hydrocarbon that OSHA has identified as one of a number of typical components of the benzene-soluble fraction of coal tar pitch volatiles. Other components include anthracene, benzo[a]pyrene, phenanthrene, acridine, and pyrene. Chrysene is characteristic of coal tar pitch volatiles (PEL is 0.2 mg/m³) and/or coke oven emissions (PEL is 0.15 mg/m³). See 29 CFR 1910.1000 Table Z-1, 29 CFR 1910.1029 - Coke oven emissions, and 1910.1002 - Coal tar pitch volatiles; interpretation of term. |
