Study of Metal Contamination in Urban Dust of Chengdu by X-Ray Fluorescence

X-ray Fluorescence was used to determine the content of 25 inorganic elements in Chengdu dust in this article, and enrichment factor was used to analyze its distribution characteristics and source apportionment. The results showed that Cr was the extremely severe pollutant, with its average concentr... Full description

description: X-ray Fluorescence was used to determine the content of 25 inorganic elements in Chengdu dust in this article, and enrichment factor was used to analyze its distribution characteristics and source apportionment. The results showed that Cr was the extremely severe pollutant, with its average concentration of 64.57μg/g, the average enrichment factor coefficient of 477.79, which was more than 10 times higher than background value, suggested it was significantly contributed by the anthropogenic sources. Ca was the heavily polluted element, with its concentration of 7.71μg/g in average, and the average enrichment factor coefficient being 12.26, which was more than 10 times of the background value, showed it was also affected by the anthropogenic sources. The enrichment factor coefficient of Na, As, Co, Cu, Mn, Ni, Pb, Se, V, Zn, K, Mg, Br, Cs was about 1 in average, illustrated that they were not obviously affected by the man-made pollution.
