中国农村儿童血铅水平分析研究

通过检索相关文献,收集国内1998～2006年公开发表的关于农村儿童血铅研究的论文,从中选择相关的文献进行综合分析。被纳入研究的49篇文献分析结果表明,我国农村儿童血铅水平在43.48～532.0μg/L,平均为105.17μg/L,中毒率范围为2.2%～88.1%,平均中毒率为26.8%。在所报道的21个省、市中,有8个省、市儿童血铅平均水平超过100μg/L。血铅平均值及铅中毒率最高的是安徽、云南、山西,最低的是湖南、重庆、吉林。受环境等因素的影响,我国农村儿童血铅水平较高,血铅的防治工作刻不容缓。

Lead Level in Blood for Chinese Countryside Children

Based on analysis of VIP Information Resource System and some related literatures published during year of 1998~2006,studies on 49 literatures indicated that average level of lead in blood for Chinese countryside children was 43.48~532.0μg/L,with average level of 105.17μg/L,toxic rate 2.2%~88.1% and average toxic rate of 26.8%.In reported 21 provinces,lead level in blood in 8 provinces went beyond 100μg/L,with highest in Anhui,Yunnan and Shanxi Province while lowest in the province of Hunan,Chongqing and Jilin.It is urgent to prevent and control lead in blood due to environment influence on lead level in countryside children.
