摘要
目的了解抚顺市铅作业工人尿铅异常发病特征。方法选择接触铅作业1年以上,且平均年龄和接触铅作业工龄及各工龄段的受检人数构成比相近的3 907名铅作业工人,分成男女两组做比较,为制定职业病防治策略提供依据。采用双硫腙测定法测定尿铅含量,尿铅正常值0.39μmol/L为判定标准,对铅作业工人的尿铅异常情况进行统计学分析。结果 2006-2013年,抚顺市铅作业工人男工组检测1 865人,尿铅异常发病率18.0%;女工组检测2 042人,尿铅异常发病率28.9%;经统计学分析,两组差异有统计学意义(P<0.001)。结论女工组尿铅异常发病率高于男工组,与女性月经期、妊娠期、哺乳期排钙量增加、生理特点及对毒物的第三性增高有关。
Objective To describe the prevalence of abnormal urine lead in workers exposed to lead in Fushun city, and provide basis for the establishment of occupational diseases prevention strategies. Methods The abnormal urine lead preva- lence was compared between male and female workers, which had similar age, exposed period and constituent number and both exposed to lead more than a year. Dithizone method was used to determine the lead content of urine. The value of 0. 39 p, mol/L was as the criterion to determine the abnormal urine. Results From 2006 to 2013, 1 865 males and 2 042 females workers exposed to lead were sampled in Fushun. The abnormal prevalence of urine lead was 18.0% for males and 28.9% for females. Conclusion Females workers exposed to lead have significant abnormal lead prevalence than that of males (P 〈0. 001). The menstrual period, pregnancy and lactation calcium excretion increase physiological characteristics and the third sex poison may be related to increase of female.
