浙江省某市工业区周边居住儿童铅蓄积状况及干预效果研究

Research on the lead accumulation and intervention effect of children living near the surroundings of industrial area of a certain city in Zhejiang

目的 调查了解工业区周边居住儿童的血铅蓄积水平,探讨降低血铅的干预效果,为制定防治策略提供科学依据.方法 2011年随机整群抽取儿童268名(暴露组)和远离工业区的儿童268名(对照组),比较其血铅水平及异常率,并研究综合干预措施的效果.结果 暴露组血铅水平为(99.96±43.27) μg/L,高于对照组的(49.69±23.97) μg/L,血铅异常率也较高,4～6岁组血铅水平最高,达到(109.71±41.18) μg/L.结论 工业区周边铅污染不容乐观.加强对儿童采取健康教育并联用辅助驱铅治疗等综合干预,是预防工业区周边儿童高铅血症和铅中毒的有效途径.

Objective To investigate the blood lead level of children liying near industrial zone,and explore the intervention effect of reducing blood lead,so as to provide scientific basis for formulating control strategies.Methods In 2011,268 children surrounding industrial zone (exposure group) and 268 children away from the industrial area(control group) were selected by cluster random sampling.The blood lead level and abnormal rate between the two groups were compared,and the effects of comprehensive intervention were studied.Results Blood lead level in the exposure group [(99.96 ± 43.27) μg/L] was higher than that in the control group [(49.69 ± 23.97) μg/L],so was the abnormal rate.The blood lead level in the 4-6 age group was the highest among all the age groups.It reached (109.71 ±41.18) μg/L.Conclusions The lead pollution in surroundings of industrial zone is not so optimistic.The effective method to prevent children from high blood lead and lead poisoning in industrial area surroundings is to strengthen health education on children,and take parallel auxiliary comprehensive intervention.
