| Abstract: | Being analysed of mass spectrum and water soluable ion composition spectrum of aerosol samples collected at Huangpu industrial aera, it is shown that the total aerosol mass and ion density are obviously higher than those of inland station in South China, their distributions show a three peak pattern obviously, the main ion compositions in aerosol are SO 2- 4, NO - 3, Ca 2 , NH 4. Compared with the inland observation station in South China, besides the double increase of ions density, the density of SO 2- 4 accounts for the large part of the negative ions, the contents of NO - 3 and NH 4 increase greatly, and the main features are that NO - 3, SO 2- 4, NH 4 and K exist mainly in mini particles. |
