目的 探讨居室环境对幼儿血铅水平的影响。方法 随机整群抽取太原市居民区某幼儿园 2～ 6岁 395名儿童为研究对象 ,用自拟问卷调查儿童居室环境 ,采指端末梢血 2 0 μl,原子吸收石墨炉法测定血铅。 结果 幼儿血铅水平与居室被动吸烟、邻近交通线、铅作业区及家庭有铅作业人员显著正相关 ,且幼儿血铅水平显著高于各对照组。前三组铅中毒率也高于各自对照组。多元逐步回归分析显示 :被动吸烟、家庭有铅作业人员是影响血铅值的高危因子。结论 不良居室环境影响幼儿血铅水平。
Objective To investigate the impact of room environment on blood lead levels in children. Methods A total of 395 children aged 2 ~ 6 years in a kindergarten in a residential area of Taiyuan City were randomly selected as the research object. The children ’s room environment was collected by self - made questionnaire and the blood lead was collected from the peripheral blood of the finger tip and blood lead by graphite furnace atomic absorption spectrometry. Results There was a significant positive correlation between the level of blood lead in children and passive smoking in the living room, the adjacent traffic lines, the lead working area and the lead workers in the family. The level of blood lead in preschool children was significantly higher than that in the control group. The first three groups of lead poisoning rates are also higher than their respective control group. Multivariate stepwise regression analysis showed that: Passive smoking, family lead workers are high risk factors affecting blood lead levels. Conclusion Adverse room environment affects the level of blood lead in children.
