| 摘 要： | One hundred and seven marine aerosol samples were collected during December 1988 to March 1990, and 3 dry deposition samples, 16 rain samples and 2 Cascade Impacter samples were collected from March to May 1990 at the southeast coast of the Xiamen Island. All the samples were analyzed for SO42-, NO3-, Cl-, Na+ , NH4+, using ion chromatography.The results indicate that the concentration of sulfate in marine aerosols over the Xiamen waters appears to be of seasonal variation, in an order of winter > spring > autumn > summer. The mean sulfate concentration lor the total marine aerosol samples over the Xiamen waters is 9. 37 μg/m3, respectively 0. 89 and 8. 48 μg/m3 for the seasalt and non-sea-salt sulfate. The distribution of sulfate shows a bimodal form with a peak in the coarse particle range which is derived from the sea-salt sulfate, and a peak in the fine particle range which is derived from the non-sea-salt sulfate. The total deposition of sulfate to the Xiamen waters is estimated to be 4. 68g/m2

| Abstract: | One hundred and seven marine aerosol samples were collected during December 1988 to March 1990, and 3 dry deposition samples, 16 rain samples and 2 Cascade Impacter samples were collected from March to May 1990 at the southeast coast of the Xiamen Island.All the samples were analyzed for SO42-, NO3-, Cl-, Na+, NH4+, using ion chromatography.
The results indicate that the concentration of sulfate in marine aerosols over the Xiamen waters appears to be of seasonal variation, in an order of winter > spring > autumn > summer.The mean sulfate concentration lor the total marine aerosol samples over the Xiamen waters is 9.37 μg/m3, respectively 0.89 and 8.48 μg/m3 for the seasalt and non-sea-salt sulfate.The distribution of sulfate shows a bimodal form with a peak in the coarse particle range which is derived from the sea-salt sulfate, and a peak in the fine particle range which is derived from the non-sea-salt sulfate.The total deposition of sulfate to the Xiamen waters is estimated to be 4.68g/m2·a, with dry and wet depositions being approximately 2.19g/m2·a respectively. |
