| Abstract: |
| 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 60 μg/m3 and 224 μg/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 PM10 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 PM2.5. |
