针对当前我国对大气砷( As)污染没有引起足够重视的现状,以PM2.5中As为研究对象,分别对其危害、变化规律、污染水平、来源解析、控制技术和标准进行分析对比. 研究表明,PM2.5中As的季节变化规律与其他重金属有一定差异,有些地区甚至表现出几乎相反的趋势;日变化规律与PM2.5呈正相关;空间变化规律与其他重金属相一致;我国PM2.5中As污染较为严重,南北方的污染程度具有一定的差别;当前我国关于大气As的相关标准比较匮乏. 通过对我国PM2.5中As的规律、污染状况及控制经验进行总结,为今后大气As的污染防治和研究提出一些建议.

There is no enough attention paid to arsenic pollution in atmosphere in China at present.The trace element arsenic in PM2.5 was studied, with its harm, variation characteristics, pollution level, sources, control technology and standards analyzed.The results show that there are differences between arsenic and other metals in PM2.5 in the rule of seasonal variation, someplace even showing almost the opposite trend.The daily variation of arsenic and PM2.5 are positively related, while the spatial variation of arsenic is the same as other metal element. The arsenic pollution in PM2.5 in China is serious, and there are some differences between northern and southern parts of the country.The relevant standard of arsenic in the air is lacking in China at present.Suggestions on arsenic pollution control and further researches were put forward based on the summarization of the variation, pollution level and control experience of arsenic in China.
