Notes on Other Potential Health Effects and Hazards

  1. EPA’s Integrated Risk Information System classifies chrysene as a probable human carcinogen based on data from animal bioassays, as human data are not available (EPA 1994).
  2. In human prostate cancer cells, chrysene [and benzo(a)pyrene] partially inhibited the dihydrotestosterone-induced production of prostate-specific antigen protein and its mRNA, indicating an anti-androgenic effect from interaction with AhR (Kizu et al. 2003).
  3. Administered via intraperitoneal injection, chrysene caused liver and lung tumors and malignant lymphoma in mice. Dermal exposure caused skin carcinomas in mice (EPA 1994).
  4. A dose-dependent lung tumor incidence was found for chrysene injected into the lungs of rats (Wenzel-Hartung et al. 1990).
  5. In one study, the lymphocyte assays of smokers with head and neck cancers had a higher prevalence of chrysene (among other polyaromatic hydrocarbons) than nonsmokers with similar cancers. The effect of chrysene alone is not known (ACGIH 2001).

Monitoring Methods used by OSHA

Laboratory Sampling/Analytical Method:
  • sampling media: Pre-cleaned Glass Fiber Filter (37 mm)
    analytical solvent: Benzene
    maximum volume: 960 Liters
    maximum flow rate: 2.0 L/min
    current analytical method: High Performance Liquid Chromatography; HPLC/UV/FLU
    method reference: OSHA Analytical Method (OSHA 58)
    method classification: Fully Validated (In conjunction with Coal Tar Pitch Volatiles and Coke Oven Emissions.)
    note: OSHA personnel can obtain pre-cleaned filters, vials, and Teflon-lined caps from SLTC. After sampling, filter must be transferred to a vial with a Teflon-lined cap. Sample must be protected from direct sunlight.
    note: 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. There is no specific OSHA PEL for chrysene. Chrysene is characteristic of cold tar pitch volatiles (PEL is 0.2 mg/m3) and/or coke oven emissions (PEL is 0.15 mg/m3).
Bulk Method: Limit the amount of bulk submitted to one gram or one mL.
