Abstract:
The pollut ion sources of part iculate mat ter in the urban ambient air of Yuxi city w ere analyzed by the chemical mass balance method ( CMB) based on receptor model. The samples of total suspended part iculate ( TSP) were collected at three sites of Municipal Environmental Monitoring Station, Day ing St reet and Dongfeng Reservoir. At the same time, the samples of 5 sources w ere collected, such as soil dust , building material dust, coal smoke dust, steel dust and t raff ic dust. Six teen element s in both source samples and receptor samples were measured by ICP- AES ( Induct ively Coupled Plasma-Atomic Emission Spect rometry) . The CMB model for Yuxi City w as developed. The contribut ion rates of five sources to TSP were got through the model calculat ing: soil dust w as 40. 75 %, building material dust w as 31. 06 % , coal smoke dust w as 18. 37 % , steel dust was 8. 09 % and t raf fic dust w as 1. 73 %.
