Worker exposures to fluoranthene (206440) (Flu), pyrene (129000) (Pyr), benz(a)anthracene (56553) (BaA), chrysene (218019) (Chr), and benzo(a)pyrene (50328) (BaP) were surveyed at Zeric Roofing Corporation (SIC-2952) in Santee, California on November 8, 1977. A new asphalt (8052424) roof was being applied by five workers. Bulk asphalt analysis indicated that concentrations of BaP, BaA, Flu, Pyr and Chr were 40, 90, 40, 220 and 130 micrograms per gram, respectively, by analysis using benzene, and 50, 100, 50, 230, and 150 micrograms per gram, respectively, by analysis using cyclohexane (110827). Personal samples for coal-tar-pitch (65996932) volatiles in asphalt indicated concentrations of BaP, BaA, Flu, Pyr and Chr ranging from 0.04 to 1.90, 0.10 to 1.90, 0.10 to 1.90, 0.23 to 1.10, and 0.29 to 1.10 micrograms per cubic meter, respectively, for different job operations. Area samples of coal-tar-pitch volatiles indicated concentrations of BaP, BaA, Flu, Pyr and Chr ranging from 10.10 to 4.20, 0.20 to 47.00, 0.74 to 10.00, 1.90 to 21.00 and 0.61 to 68.00 micrograms per cubic meter, respectively. The authors conclude that a potential health hazard exists from exposure to polynuclear aromatic hydrocarbons. They recommend engineering controls to reduce emissions, standard hygienic practices to reduce exposures and training programs for workers to avoid health hazards.
