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