[Objective]The research aimed to determine and analyze the water-soluble acid ions content in atmospheric particles on the eastern outskirts of Chengdu, Sichuan Province. [Method] The ions chromatography was used to determine and analyze the different size (grading) of respirable particles and their main acidic ions content and features at the region on the eastern outskirts of Chengdu in the second half of 2007 and in the first half of 2008. Meanwhile, they were compared with the results of samples in the same period of 2006 respectively, to obtain the atmospheric particles comprehensive regulation before and after on industrial pollution source of Chengdu City and the change law of main acid ions content. [Result] In different grading samples, the ions total concentration and the different ion concentration of the samples diameter was 0.65-2.10 μm were significant higer than the other gradings. Thereinto, the enrichment amount of the water-soluble acid ions was the biggest, which was same as that of 2006. [Conclusion] The fine particles on the eastern outskirts of Chengdu had the biggest harm to people.
