A survey of middle-aged men in 24 British towns has found pronounced geographical variation in blood lead concentrations. Towns with the highest mean blood lead concentrations have soft water supplies and have the highest water lead concentrations. Individual blood lead can be considerably increased by raised household tap water lead concentrations. Mean blood lead is estimated to be 43% higher for men when the concentration of lead in first-draw domestic tap water is 100 micrograms/l compared with a zero concentration. Individual blood lead is also affected by alcohol consumption and cigarette smoking, such that on average these two life-style habits together contribute an estimated 17% to the blood concentration of lead in middle-aged men. Lead in water should be given greater priority in any national campaign to reduce lead exposure.
一项针对英国24个城镇中年男性的调查发现,血铅浓度存在明显的地域差异。平均血铅浓度最高的城镇供水水质较软,水中铅含量也最高。家庭自来水铅浓度升高会使个人血铅水平显著增加。与铅浓度为零相比,当家庭首次抽取的自来水铅浓度为100微克/升时,男性的平均血铅估计高出43%。个人血铅水平还受饮酒和吸烟影响,平均而言,这两种生活习惯共同导致中年男性血铅浓度升高约17%。在任何全国性的减少铅暴露运动中,水中铅的问题都应得到更高的重视。
