Abstract
The lead burdens for children and mothers exposed to lead-contaminated soils and dusts have been investigated in a rural district with minimal atmospheric pollution. A significant relationship was observed between the lead content of blood and hair of children exposed to soils of mean lead content in the range 420-13,969 p.p.m. The blood lead concentration of children was consistently greater than that of their mothers. No consistent relationship was found between blood lead values and pica for soil. In this situation, lead in soil provided a small additional burden for children but in itself was insufficient to constitute a hazard.
摘要
在一个空气污染极小的农村地区，对接触铅污染土壤和灰尘的儿童及母亲的铅负荷进行了调查。在接触平均铅含量范围为420 - 13,969 ppm土壤的儿童中，观察到血液和头发中的铅含量之间存在显著关系。儿童的血铅浓度一直高于其母亲。未发现血铅值与食土癖之间存在一致关系。在这种情况下，土壤中的铅给儿童带来了少量额外负担，但就其本身而言不足以构成危害。
