In May 1990, the New Jersey State Department of Health (NJSDH) received laboratory reports of elevated blood lead levels [( BLLs] greater than or equal to 25 micrograms/dL) for 13 workers employed at a small foundry in New Jersey. Six of the workers had BLLs that exceeded 60 micrograms/dL; the highest was 277 micrograms/dL. According to the Occupational Safety and Health Administration's (OSHA) lead standard,* these six persons should have been removed immediately from further exposure to lead until their BLLs returned to acceptable ranges. NJSDH contacted the persons with elevated BLLs to obtain additional information about their lead exposures and health status. None of these persons had been evaluated medically or removed from the source of lead exposure.
