Title: The Concentration and Size Distribution of Soluble Inorganic Ion in PM_(10),PM_(2.5) in Ningbo
Abstract: The research on the concentration,size distribution of soluble inorganic ion in PM_(10),PM_(2.5) were conducted in Ningbo in 2004.The results show that Cl~-,SO_4~(2-),NO_3~- in PM_(10) was 1.00,9.90,3.70μg/m~3 respectively.And Cl~- were mainly found in the 2.5~10μm fraction,whereas SO_4~(2-),NO_3~- were mainly existed in PM_(2.5),Significantly seasonal variations were also found with the trend of higher level in winter and lower in summer.
