Phase III Survey Report No. 1, Work Exposure to Polyaromatic Hydrocarbons at Selected Petroleum Refinery Process Units, Champlin Petroleum Refinery, Enid, Oklahoma.
NIOSH 1980 Jun:51 pages
Worker exposures to polyaromatic-hydrocarbons (PAHs) were determined at the Champlin Petroleum Refinery (SIC-2911) in Enid, Oklahoma on November 30 to December 1, 1979. The survey was part of a NIOSH sponsored study characterizing worker exposure to PAHs at petroleum refineries. Personal and area air samples were collected in the fluid catalytic cracker unit (FCCU) and delayed coker units and area samples in the asphalt processing unit. All 35 of the personal and area air samples had detectable quantities of at least five PAHs or groups of PAHs. The cumulative PAH concentration for individual samples ranged from less than 1 microgram per cubic meter to 150 micrograms per cubic meter. Two upwind boundary samples were each less than 1 microgram per cubic meter. The author concludes that workers at the FCCU and delayed coker unit of this refinery were exposed to numerous PAHs, generally at low concentrations.
