目的：探讨儿童血错水平及其影响因素。方法：采集1109名6～10岁儿童末稍血，用原子吸收分光光度法测定血铅，同时进行个人及家庭情况调查。结果：儿童血铅均值为1533ng／L，血铅超标儿童占刀％。儿童血错水平随年龄的增长而增加，8岁组与9岁组对岁组与10岁组儿童血铅水平有显著性差异（尸＜0．of）；干部、职员子女血铅水平显著低于司机、答家及个体商贩子女。结论：儿童血错超标严重，父母接触铅及环境铅污染增加了儿童铅吸收的风险。
Objective: To explore the level of children’s blood-stained blood and its influencing factors. Methods: A total of 1109 children aged 6 to 10 years were collected to measure blood lead by atomic absorption spectrophotometry. Personal and family conditions were also investigated. Results: The mean blood lead of children was 1533 ng / L, and the excess of blood lead accounted for knife%. Children’s blood level of error increased with the increase of age, 8-year-old group and 9-year-old group of children aged 10 and 10 were significantly different levels of blood lead (P <0.of); cadres, staff children blood lead levels were significantly lower For drivers, aiders and individual dealers children. CONCLUSIONS: Children have severe bloodstains that exceed the standard. Children exposed to lead and environmental lead have increased the risk of lead absorption by children.
