摘　　要：在严格的质量保证措施下，对北京石景山地区２７０名孕妇及其婴儿进行了血铅的追踪调查。结果显示：孕３月血铅水平为４５．０μｇ／Ｌ，分娩前血铅水平为６４．８μｇ／Ｌ，孕期血铅呈升高趋势，其中后３月升高明显，分娩前血铅约为孕３月血铅的１．５倍；脐带血铅水平为５１．９μｇ／Ｌ，其中有１０．４％的胎儿脐血铅高于１００μｇ／Ｌ；婴幼儿血铅随月龄增加呈升高趋势，６月龄后升高明显。相关分析显示：妊娠３月血铅与妊娠６月血铅之间、分娩前血铅与脐带血铅之间、脐带血铅与婴幼儿血铅之间均有显著相关关系（Ｐ＜０．０１），其中分娩前血铅与脐带血铅之间、６月龄血铅与１２月龄血铅之间的相关系数分别为０．８０、０．４７。作者对孕期血铅升高及婴幼儿血铅随月龄升高的原因进行了分析。Under strict quality control,the authors investigated the levels of PbB among 270 women from early pregnancy to delivery and their infants.The mean PbB levels of the first three months of pregnancy and delivery is 45 0μg/L and 64 8μg/L respectively.Analysis shows an increase of mean PbB level in the period of gestation,and a significant increase in the last three months.The mean PbB level of umbilical cord is 51 9μg/L (10 4% umbilical cord PbB>100μg/L).The mean PbB level of infants increases with the months,it increases significantly after six months.Regression analysis confirmed the positive correlation between the PbB levels of first three and second three months of gestation,the PbB of delivery and umbilical cord, the PbB of umbilical coral and infants.The correlation coefficient of the PbB level of delivery and umbilical cord, the PbB level of infants at six months and at twelve months is 0 80 and 0 47 respectively.
