乌鲁木齐大气总悬浮颗粒物（TSP）离子化学组分及影响因素
The Features of Ionic Components of TSP and Their Affecting Factors over Urumqi
摘要
Abstract
This paper analyzed the water-soluble ionic components of TSP over Urumqi in 2009 based on the data of atmospheric total suspended particles （TSP） measured with ion chromatographers at 4 observation sites. The results are as follows： （1） The total ion concentration which was averaged with the values measured at three stations over Urumqi City was 151.28 μg/m3 , and the total ion concentration at Baiyang Station was 40.83 μg/m3. The ratio of NO3-/SO24- at all the 4 stations was low, which revealed that the atmospheric pollution was mainly from the fixed pol- lution sources in Urumqi; （2） SO24-, Ca2＋ , NO3- and NH4＋ levels were higher than the other ions of TSP in 2009. There were the significant seasonal variations of concentration of ions. All the concentrations of ions, especially that of SOl- and NO3- , were obviously increased in heating season; （3） Correlation analyses of all the ions were carried out, the results showed that the correlation coefficient between NH4＋ and SO42- was 0.828, and that between NH; and NO3- was O. 659, these revealed that ammonium compounds were dominated by ammonium sulfate and ammonium ni- trate. The correlation coefficient between NO3- and SOl- was 0.973, which revealed that NO3- and SOl- came mainly from sulfur dioxide and nitrogen oxides. There was a good correlation between crust elements Ca2＋ and Mg2＋ , and their correlation coefficient was as high as 0. 914, which revealed that the sources of these two crust elements were similar, and these elements came mainly from dust weather, road dust and construction dust.关键词
