【摘要】 目的:了解珠海市人群的胎儿铅暴露水平及其影响因素。方法:在珠海市收集脐带血标本81份,用电感耦合高频等离子体发射光谱仪测定血铅浓度,并以面谈问卷的形式对相应的81名产妇进行了社会环境及家庭生活因素调查。结果:81例脐带血血铅水平呈正态分布,范围在0590μg/L。平均值为150μg/L。脐带血血铅水平超过目前认为的安全界限(100μg/L)占67.9%。研究还发现孕妇居住房屋年代、孕妇居住地、孕期食用罐头食品是胎儿铅暴露的危险因素。多元Logistic回归分析发现,食用罐头食品对脐血铅水平的贡献在考虑了其他掺杂因素的影响后仍有统计学意义。结论:目前珠海市环境铅污染状况可能对胎儿的发育产生不利影响。更多还原

【Abstract】 Ojective :To study fetal exposure to lead and its related factors.Methods: 81 specimens of umbilical cord blood were collected and blood lead levels determined in Zhuhai. Furthermore related 81 lying in women were surveyed about environmental and home life factors with a face to face questionnaire. Result:The result showed that umbilical cord blood lead levels in 81 cases were normal distribution with a range of 0 to 590 μg/L, the mean was 150μg/L. Specimens with umbilical cord blood lead level exceeding the safe criteria of 100μg/L accounted for 67.9 percent of the total. The study also found that pregnant women with house age, living area and canned food were risk factors for fetal lead exposure. As a result of logistic multiple regression canned food was a statistical significance. Conclusion:The present situation of Pb pollution in Zhuhai may do harm to the fetus growth.更多还原
