【摘要】 本文对湖南省某工业区及乡村区各三十余名正常分娩的产妇进行了胎盘及脐带血中镉、铅、汞含量的测定。结果表明此三种金属均能在胎盘中蓄积,并进入脐带血中。工业区所有测定值 均高于乡村区。因此,镉、铅、汞造成的环境污染通过妊娠对胎儿造成危害是值得注意的。更多还原

【Abstract】 Cadmium (Cd), lead (Pb), and mercury (Hg) levels in placenta and cord blood of 37 lying-in women living in an industrial-waste-contaminanted area is compared with those in the rural non-contaminanted area. The median values in placenta of the industrial area were 15.8, 38.3, and 25.2μg/100g (dry weight) for Cd, Pb, and Hg, respectively, while in rural area were 5.2, 25.5,12.9μg/100g. The median values in cord blood of the industrial area were 0.8,12. 2,7.5μg/100ml and 0.4,6.4, 2.2μg/100ml in rural area. All of the values in the industrial area were significantly higher than that of the rural area(p<0.05 and p<0.01). It is indicated that environmental pollution with Cd, Pb and Hg can do harm to fetus.更多还原
