The water supply in Ayr (Scotland, UK) was plumbosolvent and many dwellings in Ayr contained lead pipes. In 1981 treatment of the water supply to reduce its plumbosolvency was initiated. Measurements of water and blood lead concentrations were made before and subsequent to the treatment. Most of the measurements made before and after water treatment began were made on water samples from the same dwellings and blood samples from the same women. Water treatment produced a sharp fall in water lead concentrations and a decrease in the median blood lead concentration from 21 to 13 micrograms/100 ml. Two women had higher than expected blood lead concentrations, both these women had been removing old paint. Women who had lead pipes removed from their dwellings all showed substantial decreases in their blood lead concentrations. The curvilinearity of the relation between blood lead and water lead concentrations is confirmed. Even relatively low (less than 40 micrograms/l) water lead concentrations may make a substantial contribution to blood lead concentrations.
英国苏格兰艾尔的供水具有铅溶解性，艾尔的许多住宅都装有铅管。1981年开始对供水进行处理以降低其铅溶解性。在处理前后对水和血铅浓度进行了测量。水处理开始前后的大多数测量是针对来自同一住宅的水样和同一女性的血样进行的。水处理使水中铅浓度急剧下降，血铅浓度中位数从21微克/100毫升降至13微克/100毫升。有两名女性的血铅浓度高于预期，这两名女性都在清除旧油漆。住宅中铅管被拆除的女性血铅浓度均大幅下降。血铅与水中铅浓度之间关系的曲线性得到了证实。即使相对较低（低于40微克/升）的水中铅浓度也可能对血铅浓度有很大影响。
