摘要
目的为了解当前我国北方某城区及其郊区儿童血铅(BPb)水平。方法选择太原市城区和其郊区1~4岁儿童进行血铅测定,城区190名;郊区207名。结果城区儿童BPb水平(μmol/L)平均为0.313,Ⅰ级为77.9%,ⅡA级为22.1%,无ⅡB级以上者;而城郊儿童BPb水平(μmol/L)平均为0.733,Ⅰ级为44.0%,ⅡA级为16.9%,ⅡB级为16.9%,Ⅱ级共33.8%,Ⅲ级为20.8%,Ⅳ级为1.4%。结论城区儿童血铅(BPb)水平分布明显低于郊区,郊区儿童铅中毒较为严重,由于低水平铅暴露对儿童健康都会产生不良的影响,所以,无论城区还是郊区,都应采取积极的预防铅污染措施,防止铅对儿童的危害。
Objective To investigate the recent status of blood Pb contents of children living in Taiyuan and its suburb. Methods The blood Pb content of 190 children living in Taiyuan city and 207 children in its suburb. Results BPb average content of the children in Taiyuan was 0.313 μmol/L,and the BPb grading was grade Ⅰ 77.9% and grade ⅡA 22.1%,There was none of grade ⅡB or over, while the BPb average content of the children in the suburb was 0.733 μmol/L, and grade Ⅰ 44.0%, grade ⅡA 16.9%, and gradeⅡB 16.9%. The gradeⅡ in all was 33.8%, grade Ⅲ 20.8% and grade Ⅳ 1.4%. Conclusion The level of blood lead in children living in Taiyuan is obviously lower than in suburb. The lead poisoning of the children in Taiyuan's suburb is more serious. Since lower lead exposing may affect children's health,an active way should be taken to prevent children from lead pollution both in city and in its suburb.
