由于工业化和城市化的快速发展，土壤、水体和大气中的重金属污染已对生物圈造成严重的环境危害。铅可能是污染环境中最常见的重金属之一。这种金属的主要来源包括金属矿石的开采和冶炼、含铅汽油的燃烧、城市污水和含铅工业废物的处理以及含铅涂料的使用（Kabata-Pendias和Pendias，1984年; Seaward和Richardson，1990年）。据报告，在一些严重污染的地点，铅的浓度相对较高。例如，路边土壤中的铅浓度高达7000微克/克升（Kabata-Pendias和Pendias，1984年），矿区土壤中的铅浓度高达13380微克/克升（Wickland，1990年）。
Heavy metal contamination of soil, water and air has caused serious environmental hazard in the biosphere due to rapid industrialization and urbanization. Lead is probably one of the most frequently encountered heavy metals in polluted environment. The primary sources of this metal include mining and smelting of metalliferous ores, burning of leaded gasoline, disposal of municipal sewage and industrial wastes enriched in lead as well as using of lead-based paint (Kabata-Pendias and Pendias 1984; Seaward and Richardson 1990). Relatively high levels of lead concentration have been reported at some severely contaminated sites. For example, lead concentrations were recorded as high as 7000 μg g -l in roadside soil (Kabata-Pendias and Pendias 1984) and 13380 μg g -l in mining district soil (Wickland 1990).
