Phase III Survey Report No. 8, Worker Exposure to Polyaromatic Hydrocarbons at Selected Petroleum Refinery Process Units, Phillips Petroleum Refinery, Great Falls, Montana.
NIOSH 1980 Oct:43 pages
Worker exposures to polyaromatic-hydrocarbons (PAHs) were determined at the Phillips Petroleum Refinery (SIC-2911) in Great Falls, Montana, on January 4 to 5, 1979, March 27 to 29, 1979, and June 10 to 12, 1980. The survey was part of a NIOSH study characterizing worker exposure to suspected carcinogens in petroleum refineries. Personal and area air samples were collected at the catalytic cracker and the asphalt unit. All 10 of the personal and area air samples had detectable quantities of at least four PAHs or groups of PAHs. The cumulative PAH concentration from individual samples ranged from 2.2 micrograms per cubic meter to 20.4 micrograms per cubic meter. Two upwind boundary samples were 0.65 and 2.41 micrograms per cubic meter. The author notes that, although several of the PAHs detected at this facility have a suspected carcinogenic potential, the lack of definitive toxicologic and epidemiologic studies on these compounds prevents any conclusions concerning the hazard at this facility.
