南通钢绳产业区儿童发铅、发锌水平调查与评价

Investigation and Evaluation of the Concentration of Pb,Zn in Children's Hair in the Steel Wire Rope Industry Area in Nantong

为调查南通市钢绳产业区儿童发铅、发锌水平,对67名5~7岁健康儿童进行了发铅、发锌的检测。结果表明：当地环境因素并没有影响儿童的身体健康。钢绳产业区学龄前儿童发铅和发锌含量的平均值均在正常参考标准值内,儿童发铅超标率为7.5%,远远低于1998年市区儿童的发铅超标率。钢绳产业区与其他地区学龄儿童发铅、发锌的含量也并没有显著差异。发铅超标率较低,主要与当地农产品中锌的含量较高有关。

The concentration of Lead and Zinc in the hair of 67 healthy children aged 5 to 7 years old were determined to investigate the Pb and Zn level in children＇s hair in the steel wire rope industry area in Nantong.The results showed that the local environmental factors didn＇t affect the children＇s heath.The average contents of Pb,Zn in the preschool children＇s hair in the steel wire rope industry area fell in normal range,and the over-standard rate of contents of Pb,Zn is only 7.5% which was significantly lower than that of children in downtown in 1998.In addition,there is no significant differences in the contents of Pb,Zn of the steel wire rope industry area and that of other areas.The results also showed that the low rate of over-standard of Pb relates to the high content of Zn in local agricultural products.
