Levels of lead ingestion and inhalation producing increased body burden of lead and clinical toxicity in adults and children are compared with usual levels of exposure. The magnitude of lead exposure from air, water, and food is estimated. Sources of high level exposure to lead are described; urban street dirt, house dust, and paint are particularly common sources of high concentrations of lead. The bioavailability of different lead compounds is reviewed as well as factors affecting susceptibility to lead.
将成年人和儿童因摄入及吸入铅而导致体内铅负荷增加和临床毒性的水平与通常的接触水平进行比较。估算了空气、水和食物中铅的接触量。描述了铅的高接触源;城市街道灰尘、室内灰尘和油漆是特别常见的高浓度铅源。综述了不同铅化合物的生物利用度以及影响铅易感性的因素。
