目的了解鹤山市某塑料制管厂作业工人的血铅和红细胞ZPP水平,为制定防止厂内铅污染、保护工人健康提供科学依据。方法采集鹤山市某塑料制管厂2014年的258名作业工人静脉血,血铅、ZPP分别用AA-6300原子吸收分光光度计、ZPP-3800血液锌原卟啉测定仪进行测定。结果 258名作业工人血铅水平为6.2μg/L~658.3μg/L,中位数为144.2μg/L,超过400μg/L的有35人,超过600μg/L的有18人,超标率为6.98%;ZPP的检测水平为0.16μmol/L~3.87μmol/L,中位数为0.95μmol/L,超过2.91μmol/L的有24人,超标率为9.30%。随着工龄的增加,各工龄组血铅水平和ZPP水平均有不同程度的升高;男、女铅作业工人血铅和红细胞ZPP含量均有相关性(r值分别为0.916、0.824,P<0.01)。结论鹤山市某塑料制管厂作业工人职业性铅中毒检出率不算高,但不能太乐观,企业必须采取有效的职业病防治措施,预防控制铅中毒发生,改善作业环境,革新工艺,防患于未然。
Objective To understand the levels of blood lead and erythrocyte ZPP in workers in a plastic pipe factory in Heshan City, and to provide a scientific basis for the prevention of lead pollution in factories and the protection of workers’ health. Methods A total of 258 workers in a plastic pipe factory in Heshan City in 2014 were enrolled in this study. Blood lead and ZPP were measured by AA-6300 atomic absorption spectrophotometer and ZPP-3800 blood zinc protoporphyrin analyzer respectively. Results The blood lead level of 258 workers was 6.2μg / L ~ 658.3μg / L, the median was 144.2μg / L, 35 cases exceeded 400μg / L, 18 cases exceeded 600μg / L, the exceeding standard rate was 6.98 %. The detection level of ZPP was 0.16μmol / L ~ 3.87μmol / L, the median was 0.95μmol / L, and over 24.1μmol / L, the excess rate was 9.30%. With the increase of seniority, the level of blood lead and the level of ZPP increased in all age groups. There was a correlation between blood lead and red blood cell ZPP levels in male and female lead workers (r = 0.916,0.824, P < 0.01). Conclusion The detection rate of occupational lead poisoning in a plastic pipe factory in Heshan City is not high, but not too optimistic. Enterprises must take effective occupational disease prevention and control measures to prevent and control lead poisoning, improve the working environment, innovate the technology and prevent it Before it.
