直到最近，人们还普遍认为存在一个血铅阈值，低于该阈值不会出现中毒的临床体征和症状。定义的限值为80.. Mu..成人为60或40 g/100 g血液。Mu.. g/100 g儿童。有证据表明这些水平太高;对成人和儿童提出了新的最高允许限度。血铅浓度的主要价值是监测人群中的异常暴露，而不是作为主要的诊断工具。
Until recently there was wide agreement that a threshold blood lead value existed below which clinical signs and symptoms of intoxication did not appear. The limit defined was one of 80 ..mu..g/100 g of blood for adults and 60 or 40 ..mu..g/100 g for children. There is evidence to show that these levels are too high; new maximum permissible limits are proposed for adults and for children. The main value of blood lead concentrations is to monitor abnormal exposure in a population rather than to serve as a major diagnostic tool.
