| 摘 要： | 为探明广州地区的酸沉降和细粒子气溶胶污染来源,在该地区用室外烟雾箱进行了环境空气中SO2反应实验研究,其结果表明:影响SO2转化速率的主要因素是SO2起始浓度、太阳光强度、相对湿度和空气中颗粒物。SO2转化速率与箱内凝结核(简称CNC)气溶胶最大浓度密切相关。气态污染物转化是该地区的细粒子空气污染的一个重要来源。

| Abstract: | An environmental chamber study of SO2 reaction was conducted in Guangzhou city to understand some processes in acidic precipitation and the source of some small particles. The results of the chamber experiments demonstrate that some important factors affecting the transformation rate of SO2 are the initial concentration of SO2, the intensity of sunlight the relative humidity(R.H.), and particles in the polluted air. The transformation rate of SO2 was strongly related to the peak concentration of condensation nuclei counter(CNC). The main source of air pollution of small particles in that region is the transformation of SO2 to sulfate aerosol. |
