目的 分析深圳市儿童血铅水平及相关因素。方法 测定本市 834名 1～ 6岁儿童的血铅含量。随机抽检深圳市 2 0 0 0～ 2 0 0 1年 6大类 15 6 8份市售食品的铅含量。问卷调查 6 11名儿童的影响血铅水平的相关因素 ,并进行多元逐步回归分析。结果 834名儿童血铅范围在 2 2 0～ 197 4μg/L之间 ,均数为 90 6 μg/L ,其中≥ 10 0 μg/L的有 317人 ,占 38 0 1%。 6大类共15 6 8份食品中 ,铅平均含量为 0 4 1mg/kg ,铅超标率 1 15 %。儿童年龄与血铅水平呈直线正相关关系。多元逐步回归分析表明家庭或幼儿园新装修、常用金属或带油漆玩具、父母吸烟、常吃含铅量高的食品、使用含铅量高的学习和生活用具等因素与血铅水平呈正相关。结论 深圳儿童血铅含量水平与生活环境的铅污染及不良的生活习惯有关 。
Objective To investigate the blood lead levels of children and to identify related risk factors in Shenzhen City. Methods A total number of 834 children aged 1～6 years were selected to test the blood lead levels. Potentially related risk factors of 611 children were collected using questionnaires. 1 568 food from 6 categories were randomly sampled to measure lead contents. A multi-variable linear regression was used to analyze the correlation between blood lead levels and risk factors. Results Blood lead contents of 834 children were from 22 0 μg/L to 197 4 μg/L, with an average value of 90 6 μg/L, of which 317 children(38 01%) were found with a blood lead level≥100 μg/L. The average value of lead contents in food was 0.41 mg/kg and 1 15% of the samples were above the standard. New decoration in family or kindergarten, metal or painted toys, parent smoking, food and commodities with high lead contents were positive correlated with blood lead contents. Conclusion Blood lead Levels of children are correlated with the lead pollution in living environments and undesirable living habits. A comprehensive Intervention program is necessary to control and prevent lead pollution problem in children.
