济南市与东营市儿童血铅及其微量元素的研究

Study on blood lead and trace elements of children in Jinan and Dongying

目的了解济南市和东营市儿童血铅水平及其锌、铁、钙、镁、铜等微量元素分布状况的差异。方法于2006年2月至9月对两市各随机抽取100名儿童进行了血铅、锌、铁、钙、镁、铜测定。并应用PEMS软件进行方差齐性检验和t检验。结果济南儿童血铁、镁高于东营儿童,血铅低于东营儿童,差异有统计学意义。结论不同地区由于地质、水质、生活习性及经济文化水平的不同,其体内微量元素和铅的水平存在差异,应该有针对性地对本地区的儿童给予相应微量元素的补充和铅中毒的防治。

Objective To understand the distributed differences of blood lead level and trace elements including zinc,iron,calcium,magnesium,copper of children between Jinan and Dongying.Methods The determination of levels of blood lead,zinc,iron,calcium,magnesium,copper were taken from 100 healthy children random sampled from Jinan and Dongying respectively from February to September 2006.Then the test for homogeneity of variance and test were carriedout by PEMS.Results The levels of blood iron,magnesium in the children of Jinan were higher than that in Dongying,but the blood lead level was lower.There were significant differences between two cities.Conclusion The distinctnesses in geology,water quality,life behaviour and levels of economy and civilization presented in different areaes,made for differences in trace elements and blood lead level of children.The complementarity of trace elements and prevention and cure of lead poisoning should be relevantly given to the native children with pertinence.
