【摘要】 目的:探讨职业性铅接触对工人血中微量元素的影响。方法:整群抽取成都某蓄电池厂铅作业工人79名(观察组)、非铅作业工人69人(对照组),对其进行血清Fe、Zn、Ca、Pb-B、Pb-U、δ-ALA、ZPP测定,并进行相关和多因素回归分析。结果:①观察组的Pb-B、Pb-U、δ-ALA、ZPP均大于对照组。②观察组的血清Fe、Zn、Ca均低于对照组。③影响血清Fe水平的因素有是否接铅、Pb-U、ZPP、锻炼;影响血清Zn水平的因素有是否接铅、Pb-B、ZPP。结论:职业性铅接触对作业工人的血清铁和血清锌影响较大,应对接触铅的工人提供健康保护措施,切实保护工人的健康与安全。更多还原

【Abstract】 Objective:To study the changes of microelements of blood caused by occupational lead exposure.Methods:Participants in this study includes the workers who exposed to lead in a lead-acid storage cell factory(n=79)and a factory who had no history of exposure to lead in Chengdu city(n=69).Serum iron(Fe),serum zinc(Zn),serum calcium(Ca),Blood lead(Pb-B),Urinary lead(Pb-U),aminolevulinic acid(ALA)and zinc protoporphyrin(ZPP)level were measured.The correlation analysis and multiple factor regression analysis were used.Results:The Pb-B,Pb-U,δ-ALA and ZPP of observe groups are all higher than control group.②The Fe-B,Zn-B,Ca-B of observe groups are all lower than control group.③The influence factor of serum iron are exposure to lead,Pb-U,ZPP and exercise;The influence factor of serum zinc are exposure to lead,Pb-B,ZPP.Conclusion:Occupational lead exposure influence the workers’ serum iron,serum zinc obviously.The occupation protection should be strengthened,and the worker’s working condition should be improved to protect the workers’ health and safe.更多还原
