【目的】　了解豫西地区 0～ 6岁儿童血铅水平现状及影响因素。　【方法】　血铅测定采用末梢血纸片法 ,并进行问卷调查。　【结果】　 5 85名儿童血铅水平均数为 0 .42 5 μmol/L ,高于目前国际公认的儿童铅中毒诊断标准≥ 0 .483 μmol/L的比例是 3 1.96%,儿童血铅水平存在显著的地域差异 ,黄金开采区最高 ,近郊城区最低 ,两地区均数分别为 0 .5 3 6μmol/L和 0 .3 19μmol/L。儿童每日在马路上时间长 ,经常啃手指、吃皮蛋及爆米花 ,经常饮用罐头饮料等是儿童血铅水平升高的主要危险因素。　【结论】　目前豫西地区儿童血铅水平较高 ,应引起高度关注 【Objective】 To understand the status and influencing factors of blood lead levels in children aged 0 ~ 6 in western Henan. 【Method】 The blood lead level was determined by the method of peripheral blood discography and questionnaire survey. 【Results】 The average level of blood lead in 5 85 children was 0.42 5 μmol / L, which was higher than the current internationally recognized diagnostic criteria for lead poisoning in children ≥ 0.483 μmol / L, which was 3.19%. The level of blood lead There was a significant regional difference. The gold mining area was the highest with the lowest suburban urban area.

Children daily on the road for a long time, often chewing on fingers, eating preserved eggs and popcorn, regular canned drinks, etc. are the main risk factors for elevated blood lead levels in children. 【Conclusion】 At present, children with high levels of blood lead in the west of Henan Province should pay high attention
