Abstract
Worker exposures to benzo(a)pyrene (50328) (BaP) are reviewed. Surveys conducted at aluminum (7429905) reduction facilities indicate that occupations with the highest exposures include anode tenders, crane workers, pot tenders, and anode batch mixers; occupational exposures to BaP are highest in a vertical anode process and lowest in a prebaked anode process. Occupational exposures to BaP at coke production facilities have ranged from 0.01 to 161 micrograms per cubic meter (microg/m3); occupations with the highest exposure are car operators, lid workers, and tar chasers. Occupational exposures at roofing sites have ranged from less than vacuuming machine operators, patching/flashing operators, and general laborers. Saturator operators, coater operators, cooling section operators, and machine tenders are exposed to the highest quantities of BaP in roofing shingle manufacturing facilities. Occupations with the highest BaP exposures at petroleum refineries include helpers and drillers in the delayed coking process. High exposures to BaP quantities may be found in coal liquefaction, cool gas works, hot forging, tire manufacturing, steel mills, ferrous foundries, carbon (7440440) impregnation processing, and airports. There is no specific federal standard for occupational exposure to BaP in the United States; the most commonly cited standard when evaluating BaP is the coal-tar-pitch (61789604) volatiles standard. The current American Conference of Governmental Industrial Hygienists threshold limit value for coal-tar-pitch volatiles is 0.2 milligram per cubic meter (mg/m3). The NIOSH recommended standard for coal tar products is a 10 hour time weighted average of population is exposed or potentially exposed to detectable quantities of BaP.
