Analysis of Lead Levels in 1320 Pre school Children of Zhejiang Province

目的：了解浙江省０～６ 岁儿童血铅水平现状。方法：采静脉血用石墨炉无火焰法测定儿童血铅浓度。结果：１３２０ 名儿童血铅平均水平为０．３９３９±０．２４７６ μｍ ｏｌ／ Ｌ。血铅浓度≥０．４８３ μｍ ｏｌ／ Ｌ的儿童共３８３ 人，占总数的２９．０２％ 。杭州市、绍兴市、常山县分别为３９．１６％ 、２７．７６％ 、１４．１９％ ，经统计学处理，有显著性差异。结论：浙江省０～６ 岁儿童体内铅负荷状况不容乐观，其中以杭州市儿童为甚，绍兴市次之。

Objective:To investigate the current lead levels in pre school children of Zhejiang province.Methods:Blood lead levels were measured by flameless atomic absorption methods.Results:The average lead level was 0.3939±0.2476 μmol/L in 1320 children.There were 29.02% of the children (383/1320) whose blood lead levels were over 0.483 μmol/L.The children with abnormal lead levels in Hangzhou,Shaoxing and Changshan were 39.16%,27.76% and 14.19% respectively.There was statistically significant difference among these regions.Conclusion:The condition of lead pollution in children aged 0 to 6 in Zhejiang province was serious,especially in Hangzhou and Shaoxing.
