National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Worker Exposure to Polyaromatic Hydrocarbons at Selected Petroleum Refinery Process Units, Chevron U.S.A. Inc. Refinery, El Segundo, California, January 15-17, 1980. Phase 3 Survey Report No. 4,

Abstract	Worker exposures to 23 individual or groups of polyaromatic hydrocarbons (PAH) and azo-heterocyclic compounds were determined at Chevron U.S.A. Inc. Refinery, El Segundo, California, on January 15-17, 1980. Area and personal samples were collected in the fluid catalytic cracker (FCC) and delayed coker units using a silver membrane filter followed by Chromosorb 102. Upwind samples at the refinery boundary line were also collected. Samples were analyzed by gas chromatography and mass spectrometry. Of 39 samples from the two process units, 38 had detectable quantities of at least 4 of the 23 PAHs (or groups of PAHs). Cumulative PAH concentrations for individual samples ranged from non detected to 145.7 micrograms per cubic meter (CuM). Upwind boundary samples averaged 2.7 micrograms/CuM. Personal samples at the FCC unit generally were more than 5 times greater than those from the delayed coker. Two total mass area samples averaged in the FCC unit also were much higher than those collected in the coker.
