Environmental samples were analyzed for calcined petroleum coke dust, crystalline silica (14808607), sulfates, sulfites, and polynuclear aromatics at Great Lakes Carbon Corporation (SIC-2999), Port Arthur, Texas in January 1982. The survey was requested by the Oil, Chemical and Atomic Workers International Union Local 4/23 on behalf of 165 employees because of reported cases of anthracosis and anthrasilicosis. Air samples were examined for total and respirable particulates, crystalline silica, sulfates, sulfites and polynuclear aromatics. Bulk samples of calcined petroleum coke were analyzed for polynuclear aromatic content. Respiratory examinations were performed. Total particulates ranged from 1.2 to 6.1 milligrams per cubic meter (mg/m3). Respirable particulates ranged from 0.17 to crystalline silica, sulfates, or sulfites were detected. Concentrations of polynuclear aromatics ranged from 0.10 to 36 micrograms/m3. Ten percent of the workers had abnormal pulmonary function test results. Abnormal tests were associated with work in the mobile equipment department. X-rays revealed no job related abnormalities. The authors conclude that a hazard from overexposure to petroleum coke dusts containing polynuclear aromatics exists. More effective methods of dust control are recommended.
