摘要
目的分析2006至2008年武汉市及周边地区不同年龄儿童血铅水平状况及变化趋势。方法采用钨舟原子吸收光谱法对24 980名儿童手指末捎血进行铅含量检测。对受检儿童按年龄进行不同形式的分组,并对检测结果进行分析。结果武汉市及周边地区儿童血铅总体水平为58.26μg/L。其中,男童血铅水平为60.12μg/L,高于女童（54.24μg/L）。2006至2008年儿童血铅水平分别为（67.51±31.02）、（60.97±32.58）和（50.32±31.02）μg/L。在不同年份各年龄组中,男性血铅均值皆高于女性。24 980例受检儿童血铅水平的分布范围分别为：≤50μg/L占44.51%,51~100μg/L占48.13%,101~200μg/L占6.68%,≥201μg/L占0.68%。儿童血铅水平≥100μg/L者占受检总数的7.35%。其中,2006至2008年受检儿童血铅中毒率分别为15.88%、7.74%和2.13%。另外,与门诊儿童血铅水平比较,体检儿童的血铅水平明显偏低（P〈0.05）。结论与以往的报道比较,武汉市儿童的血铅水平以及铅中毒率已有明显下降。近3年来,武汉市及周边地区儿童血铅含量呈逐年递减的趋势,其中以2008年度受检儿童血铅水平下降尤为明显。
Objective To analyze the blood lead level of different-aged children and the trend to change in Wuhan and the surrounding areas from 2006 to 2008.Methods The lead content in peripheral blood of 24 980 children was determined by wolfram atomic absorption spectrometer.The children were classified into several groups by age in different forms,and the data were analyzed statistically.Results The mean blood lead level of 24 980 children from Wuhan and the surrounding areas was 58.26 μg/L.Among them,the average blood lead in boys（60.12 μg/L） was higher than girls（54.24 μg/L）.The average blood lead levels of the children in year 2006,2007 and 2008 were（67.51±31.02）,（60.97±32.58）and（50.32±31.02）μg/L,respectively.In different age groups,the blood lead level in boys was higher than that in girls.In blood lead levels of 24 980 children,44.51% of children accounted for less than 50 μg/L,48.13% accounted for 51-100 μg/L,6.68% accounted for 101-200 μg/L,and 0.68% accounted for 201 μg/L or more.7.35% of the children were found with blood lead level ≥100 μg/L.In year 2006,2007 and 2008,blood lead poisoning rates of the children were 15.88%,7.74% and 2.13%,respectively.In addition,compared with children in outpatients,children with health examination had lower blood lead levels（P〈0.05）.Conclusions From 2006 to 2008,children′s blood lead levels and lead poisoning rates in Wuhan and the surrounding areas have annually decreased,and the trend to descend is remarkable in 2008.
