Chemical composition of water-soluble ions in spring aerosol at a semi-arid site of Tongyu,China
【摘要】:正Fine aerosol samples (PM2.5) were collected daily at Tongyu, a semi-arid site in northeast China from April to June 2006,when Asian dust events occurred frequently. The concentrations of nine water-soluble ions were determined in the filter samples. The results showed that the mean mass level of PM2.5 at Tongyu station was 260.9
