摘要
为探讨低水平环境铅暴露对新婚育龄夫妇和出生婴幼儿血铅水平的影响 ,在沈阳市 3个区选择新婚夫妇进行跟踪调查 ,采集女方孕前、孕中、产前的静脉血和分娩脐带血 ,同时孕前采集其丈夫一次静脉血。对其后出生的小孩跟踪至 30个月 ,每 6个月采集一次足跟末梢血 ,测定铅浓度。新婚夫妇孕前及女方孕中、产前和脐带血的血铅水平均是污染区显著的高于对照区 (P <0 0 5 )。二区≥ 2 0 μg/dl男性分别为 19 6 %和7 6 % ,女性分别为 10 7%和 4 0 %。产前及脐带血铅水平较之孕前有逐渐减低的趋势。测定 2 0 6例次婴幼儿不同时期的血铅表明 :随着出生月份的增加有逐渐增高的趋势。出生后不同月份婴幼儿的血铅浓度污染区高于对照区 ,但差异没有显著性。
In order to explore the relationship between newlywed exposed to low environmental lead levels and their new-borne babies, we monitored the vein blood lead levels from 692 pairs of young couples shortly after their marriage.781 samples of women's vein blood of mid-pregnancy, right before giving birth and from umbilical cord were also collcted for lead testing. 206 samples of peripheral blood from heels of their babies from 6 to 30months of age were also collected and tested for lead under none-lead conditions. The average blood lead levels from both men and women living in the polluted area were all significantly higher than those in control area(P<0.05).The percentage of ≥20μg/dl blood lead levels for man were 19. 6% in polluted area and 7.6%in control ones, and for women were 10. 7% in polluted area and 4.0% in control ones. The blood lead levels had a decline trend from early pregnancy to late and umbilical cord compared to that of pre-pregnancy ones. While that for infants the bigger of age the higher lead levels. The average levels of lead for infants in polluted area were higher than in control area in all age groups, but no stgnificance were observed.
