Blood lead levels of healthy Karachi population were estimated. Mean levels for males, females, soldiers and school children were 34.4, 31.8, 29.9 and 38.2 micrograms/dl respectively. About 93% cases of either sex had elevated lead levels, of whom 30% males and 10% females had levels above the safety limits (40 micrograms/dl). Soldiers living in relatively pollution free area though had levels lower than the rest of the population but 91% had levels over 25 micrograms/dl and only two had acceptable levels. Ninety-two percent children showed levels above 25 micrograms/dl with a large number having levels over 40 micrograms/dl. A very small percentage had normal levels. Pollution by traffic exhaust was assumed to be the principal cause for these high levels.
对卡拉奇健康人群的血铅水平进行了估算。男性、女性、士兵和学童的平均血铅水平分别为34.4、31.8、29.9和38.2微克/分升。大约93%的男女血铅水平都有所升高，其中30%的男性和10%的女性血铅水平超过安全限值（40微克/分升）。生活在相对无污染地区的士兵血铅水平虽低于其他人群，但91%的士兵血铅水平超过25微克/分升，只有两人的血铅水平处于可接受范围。92%的儿童血铅水平超过25微克/分升，其中大量儿童血铅水平超过40微克/分升。只有极小比例的儿童血铅水平正常。交通尾气污染被认为是这些高血铅水平的主要原因。
