Abstract
Environmental and breathing zone samples were analyzed for 1,1,1- trichloroethane (71556), toluene (108883), petroleum distillate, lead (7439921), quartz (14808607), cristobalite (14464461), and total particulates at Crystal Zoo (SIC-3229), Boulder, Colorado in August, 1984. The evaluation was requested by the management because of concern for the workers' health. Medical questionnaires were administered to eight workers in the leaded crystal grinding room. Blood lead and free erythrocyte protoporphyrin (FEP) concentrations were measured in the grinding room workers and in three comparisons. All exposures were below the relevant standards except for lead. Five of six air samples exceeded the OSHA standard of 0.005 milligram per cubic meter (mg/m3) for lead. The lead concentrations ranged from 0.3 to 0.08mg/m3. The mean blood lead concentration in grinding room workers was 29.1 micrograms per deciliter (microg/dl); values in comparisons averaged 7.2microg/dl. No excessive lead concentrations (over 40microg/dl) were found. No evidence of lead toxicity was found. FEP concentrations averaged 31.4microg/dl in the exposed workers and 21.6microg/dl in the comparisons. The authors conclude that a health hazard due to overexposure to lead exists in the grinding department. Recommendations include improving work practices, prohibiting dry grinding or polishing of leaded glass, and installing down draft ventilation.
