摘要
简述了大气中铅污染的主要来源、铅的毒性及其在人发、血液及尿中的参考值。采用双膜法收集了大气样品，并用阳极溶出伏安法测定了北大园区内铅的水平，结果表明，大气中铅主要存在于＜10m的细粒子中。北大校园内大气中铅的浓度低于国家规定的血级地区标准。
The main sources of lead in atmosphere, the toxicity of lead and its normal level in humanhair, blood, urine have been summarized in this paper. With filter packs method for the samplecolledc tion and ASV for analysis, atmospheric lead has been measured in the campus of Beijing University. Theresults indicate lead is mainly existed in fine particles （≤ 10 Um). Atmospheric concentration of Pb inBeijing University is lower than the second grade of the national standard.
