Abstract
Environmental and medical surveys were conducted on April 19 and 20, 1977, to evaluate employee exposures to lead (7439921) at the Keystone Resources (SIC-5093), Custom Recovery Division in Mars, Pennsylvania. The evaluation was requested by an authorized employee representative on behalf of the 53 employees. Blood lead analyses of 37 workers revealed that 19 were below 40 micrograms per deciliter and 18 were in the 40 to 60 micrograms per deciliter range. Analysis of 34 urine specimens revealed that 15 were above 100 micrograms per liter. Sixteen of the 37 blood samples had a free erythrocyte protoporphyrin value greater than 300 micrograms per 100 milliliters of erythrocytes. Several cases of elevated blood urea nitrogen and creatinine concentrations were reported. Air sampling for lead showed decreasing lead concentrations with time. The authors conclude that a lead intoxication problem did not currently exist, but one probably did exist in the past. The authors recommend that the company closely follow their own lead safety program for employee health, including medical surveillance, good work practices, environmental monitoring and maintenance of ventilation systems.
