目的:评估本地区汞污染现状,分析宫内汞暴露高危因素。方法:对入院产妇进行为期1年的健康问卷调查,对所分娩的新生儿测定发汞值。结果:2 321例胎发汞均值244.38 mg/kg。胎发汞与孕妇生活居住在纺织、电子、塑胶、印染等工厂附近,有镶牙史,孕期较多食用海鱼或淡水鱼,常用化妆品、生活燃煤和丈夫吸烟明显相关(P均<0.01)。结论:本地区汞污染处于较低水平。除工业排污外,食鱼、化妆品、燃煤、镶牙、香烟是日常生活中主要的汞暴露因素,孕期应予避免,防止胎儿在宫内即受到汞和甲基汞污染。
Objective: To assess the status of mercury pollution in the region and to analyze the risk factors of intrauterine mercury exposure. Methods: A one-year health survey of hospitalized mothers was conducted. Mercury levels were determined for newborns delivered. Results: The mean of 2 321 fetuses was 244.38 mg / kg. Hg mercury and pregnant women living in the textile, electronics, plastics, printing and dyeing and other factories in the vicinity of a denture, eating more during pregnancy, marine fish or freshwater fish, cosmetics, living coal and husband smoking were significantly associated (P all <0.01). Conclusion: Mercury pollution in the region is at a low level. In addition to industrial sewage, fish, cosmetics, coal, dentures and cigarettes are the major mercury exposures in daily life and should be avoided during pregnancy to prevent the fetus from being contaminated with mercury and methylmercury in the womb.
