在一项关于血铅与自来水之间关系的研究中，对9至12岁学童的113份血液样本和140份自来水样本进行了分析。血铅中值和最大值分别为8.3和34.0 μ g/dl，自来水铅中值分别为24和2600 μ g/l。大约50%的房屋使用铅管。自来水的pH值在5.0 ~ 8.1之间变化。所涉及的两个因素，即铅管和酸性自来水，必须加以修正，以减少德国某些地区或地点的铅接触。越来越多的证据表明，当血铅水平超过10 μ g/dl时，对儿童中枢神经系统产生不利影响，这一必要性得到了强调。
In a study of associations between lead in blood and in tap-water, 113 blood samples and 140 tap-water samples of schoolchildren aged 9 to 12 years were analysed. Median and maximum values of blood lead were 8.3 and 34.0 mu g/dl and of lead in tap water 24 and 2600 mu g/l. Lead pipes were in use in some 50% of the houses. The pH values of the tap-water varied from 5.0 to 8.1. Both factors involved, i.e., lead pipes and acidic tap-water, have to be amended in order to reduce lead exposure in some regions or locations in Germany. This necessity is emphasized by increasing evidence of adverse effects to the central nervous system in children when blood lead levels exceed 10 mu g/dl.
