Personal breathing zone air samples, and blood specimens were collected on August 9, 1979 from radiator repair workers at the Aero Radiator Service (SIC-7539) in Denver, Colorado, to evaluate exposures to lead (7439921). The owner of the repair shop requested the evaluation on behalf an unspecified number of employees. Personal air samples were collected during an 8 hour work shift, and analyzed by atomic absorption spectroscopy. Blood specimens were analyzed for lead and free erythrocyte protoporphyrin (FEP). Three employees were exposed to airborne lead concentrations of 50 to 70 micrograms per cubic meter; the current OSHA standard is 50 micrograms per cubic meter. The same three employees had blood lead concentrations of 44 to 62 micrograms per 100 milliliter. The OSHA recommended limit is 40 micrograms per 100 milliliter. Two of these three employees had FEP values of 2,427 and 3,790 micrograms per liter of red blood cells. The normal range of FEP is 220 to 870 micrograms per liter of red blood cells. The authors recommend improved housekeeping and personal hygiene habits to reduce lead exposure. Local exhaust ventilation systems should be installed.
