Phase III Survey Report No. 6, Worker Exposure to Polyaromatic Hydrocarbons at Selected Petroleum Refinery Process Units, Koch Refining Company Rosemount, Minnesota.
NIOSH 1980 Oct:39 pages
Worker exposures to polyaromatic-hydrocarbons (PAHs) were determined at the Koch Refining Company (SIC-2911), in Rosemount, Minnesota, on May 13 to 15, 1980. Personal and area air samples were collected in the fluid catalytic cracker and delayed coker units and area samples in the two asphalt processing units. Thirty two of the 33 personal and area air samples had detectable quantities of at least five PAHs or groups of PAHs. The cumulative PAH concentrations for individual samples ranged from none detected. Two upwind boundary samples ranged from none detected to 0.3 micrograms per cubic meter. The author concludes that workers at the fluid catalytic cracker unit and delayed coker unit were exposed to numerous PAHs, generally at low concentrations.
