目的了解云南省某大型矿企职工尿铅、尿镉超标情况,为评价职工健康状况提供依据。方法收集该矿企11个分厂职工尿液,应用岛津6300原子吸收分光光度计分别进行尿铅和尿镉检测。结果 3 841名职工进行尿铅检测,有227例的尿铅含量异常,尿铅异常百分率为5.91%,尿铅含量范围为0.34～3.64μmol/L。异常者中有59%尿铅结果在“观察对象”值2倍以下。有3个分厂职工的尿铅平均异常百分率偏高,分别为23.33%、20.35%、12.5%。对2 442名职工进行尿镉检测,有11例尿镉含量超过0.04μmol/L,尿镉异常百分率为0.45%,尿镉含量范围为0.042～0.52μmol/L。结论部分分厂职工尿铅、尿镉异常百分率偏高,需加强作业工人的职业病防护和定期进行职业健康检查。
Objective To understand the situation of urinary lead and urinary cadmium in a large-scale mining enterprise in Yunnan Province and provide the basis for evaluating the health status of workers. Methods Urine was collected from 11 branch workers in this mining enterprise. Urine and urine cadmium were detected by Shimadzu 6300 atomic absorption spectrophotometer. Results A total of 3 841 workers performed urine lead testing. There were 227 cases of abnormal urine lead, 5.91% of urine lead, and 0.34-3.64μmol / L of lead in urine. 59% of patients with abnormal urine lead results were less than 2 times the value of “Subjects”. The average abnormal percentage of urinary lead in three branch workers was 23.33%, 20.35% and 12.5% respectively. Urinary cadmium was detected in 2 442 workers. Eleven urinary cadmium concentrations exceeded 0.04 μmol / L, urinary cadmium anomalies percentage was 0.45%, and urinary cadmium concentrations ranged from 0.042 to 0.52 μmol / L. Conclusion Some of the factory workers had higher urinary lead and urinary cadmium abnormalities, and occupational disease prevention and regular occupational health checkups should be strengthened.
