Title: Health-hazard evaluation report HETA 82-341-1682, Great Lakes Carbon, Wilmington, California

An evaluation of environmental conditions and possible health effects among workers exposed to coke dust was conducted. Personal breathing-zone (PBZ) concentrations of total airborne dust ranged from 0.1 to 12 milligrams/cubic meter (mg/m3) with a median of 1.6 mg/m3; mass median particle diameter was about 8 micrometers. Very high PBZ concentrations of coke dust occurred during a semimonthly cleanup of underground coke pits; levels ranged from 98 to 190mg/m3 with a mean of 140mg/m3. Oil mists were not detected. Exposures to polynuclear aromatic compounds were below the analytical limit of detection among workers for routine jobs. Abnormal pulmonary function tests were found in 12% of those tested. Five cases of chronic bronchitis and seven of chronic cough, 10 and 13% respectively, were identified among those interviewed. The authors conclude that there were potentially hazardous exposures to high dust levels during semimonthly coke-pit cleaning jobs.
