In this study, mine enterprise employees with excessive lead and zinc in their urine were evaluated. The concentration variation of plumbum in blood (PbB), plumbum in urine (PbU), erythrocyte zinc protoporphyrin (ZPP) in the treating process was investigated, and the effect of removing lead treatment was evaluated. After the treatment, according to “Diagnostic Criteria of Occupational Chronic Plumbum Poisoning” (GBZ 37-2002), the collective diagnosis was conducted. The value of PbB, PbU, ZPP in the process of removing lead treatment was collected. The t test and ø2 test were adopted for data analysis, and 2 variables related to linear regression analysis was performed. Of the 227 employees with excessive lead in urine, the percentage of lead poisoning observation objects in clinic, mild lead poisoning, moderate lead poisoning was 3.07%, 2.71%, 0.13% respectively. The clinical observation objects received 1.92 treatment courses in average, 2.76 courses of the mild lead poisoning, 3.80 of the moderate lead poisoning, respectively. After the course of treatment, satisfactory curative effect could be obtained. The authors concluded that the curative effect of removing lead treatment is satisfied among employees with excessive lead in urine in this enterprise.
