Surveys were conducted in four areas in Wales with differing degrees of environmental lead. In two areas the source of the lead was traffic and in one it was spoil from lead mining in the past. The fourth area, which served as a control, was a village remote from heavy traffic, industry, and lead mining. Various environmental samples were taken, and children aged 1-3 years and their mothers were studied. Blood lead concentrations were raised in the lead mining area, and within the areas defined by traffic flow the blood lead concentrations of the mothers showed a gradient. Pica in the children, assessed by a questionnaire, showed no relation with blood lead, but the amount of lead removed from the children's hands with 'wet wipes' was an important contributor to blood lead concentrations.
在威尔士的四个环境铅污染程度不同的地区进行了调查。其中两个地区铅的来源是交通，另一个地区铅的来源是过去铅矿开采的废弃物。作为对照的第四个地区是一个远离繁忙交通、工业和铅矿开采的村庄。采集了各种环境样本，并对1至3岁的儿童及其母亲进行了研究。铅矿区儿童的血铅浓度升高，在交通流量界定的区域内，母亲的血铅浓度呈现出梯度变化。通过问卷调查评估，儿童的异食癖与血铅无关，但用“湿纸巾”从儿童手上清除的铅量是血铅浓度的一个重要影响因素。
