摘　　要：对不同地区、不同工艺的4家铅冶炼企业大气污染源及环境空气进行监测和分析。结果表明,在艾萨炉和鼓风炉所排烟气的PM_(10)中,铅的平均浓度分别为60μg/m^3和224μg/m^3,对比2个铅冶炼企业的有组织排放,PM_(10)中含有的铅主要分布于PM_(2.5)中,平均占75%。对2个铅冶炼企业的无组织排放源周边空气调查表明,PM_(10)中含有铅也主要分布在PM_(2.5)中,平均占74.2%,而且PM_(2.5)中的铅占TSP中铅的47.5%。企业有组织和无组织排放面源中的铅均以细颗粒为主,主要分布在其所排的PM_(10)中,又以PM_(2.5)为主。Atmospheric pollution source and ambient air from four different lead smelters with four different processes were monitored and analyzed. The results show that average lead concentration in PM10 of outlet smoke of ISA furnace and blast furnace is 60μg/m3 and 224μg/m3 respectively. Based on investigation of organized emissions from two lead smelters, lead in PM10 is mainly distributed in PM2.5 with average of 75%. Based on research on air surrounding and non-organized emission source from two lead smelters, lead in PMlo is mainly distributed in PM2. 5 with average of 74.2 %, and lead in PM2.5 accounts for 47.5% of lead in TSP. Lead in organized and non-organized emissions source is mainly distributed in PM10, especially in PM2.s.
