The biological exposure index of blood lead concentration (PBB), medical surveillance and environmental monitoring were conducted in this study. There were 267 males and 23 female in a lead exposure group and 104 males, 5 females in a non-lead exposure group. Pbb was tested by furance atomic absorption. Physical examinations were conducted by occupational doctors. The mean Pbb level of military workers was 9.2 ±5.48ug/dI(n=288). The mean Pbb level of male lead exposure workers was 9.01±5.26ug/dl (n=265), the maximum level of Pbb was 39.37ug/dl. The mean Pbb level of female lead workers was 11.46 ±7.37ug/dI(n=23), the maximum level of Pbb was 27.08ug/dl. The Pbb level of all participants were below biological exposure index (BEI) 40ug/dl which were recommdated by WHO. The military occupations at highest risk for exposure to lead are from highest to lowest : 1. lead-smelter workers (24.71 ±13.11ug/di, n=3)，2. target card-changing workers (24.65 ± 3.13ug/dl,n=3)，3. firing workers (18.56± 7.78 ug/dl, n=17)，4. lead cored chopping workers (15.77± 3.68 ug/dl，n=6)，5. bullet manufacturing worker (10.79±3.83 ug/dl, n=36). There was no corelation with lead in medical surveillance. The result of environmental monitoring indicated that there were 2 area samples and 1 personal sample exceeded the air lead concentration of National Standard (0.1mg/m3). Recommdations were made to firing ranges to correctly imporve the effect of ventilation and to target cardchanging workers to wear personal respirarory protection when entering target area of firing range.
