| 摘 要： | 对广州市区PM2.5的污染状况进行了分析,结果表明广州市区的PM2.5呈现冬季浓度较高,夏季较低的季节性特征;PM2.5的日变化呈现出明显的双峰形;与PM10的相关性分析表明,PM2.5与PM10具有良好的线性关系。PM2.5/PM10的值约为0.59,表明广州市区空气中细颗粒物在PM10中的比重大于粗颗粒物,鉴于PM2.5的危害性及所占比例,应重视对其的监测。

| Abstract: | In this paper,the pollution characteristic of PM2.5 in urban Guangzhou was investigated.The results showed that the concentrations of PM2.5 were higher than those in summer and the daily variation of PM2.5 showed two high peaks.Concentrations of PM2.5 showed good linear relationship with those of PM10.The ratio of PM2.5/PM10 was nearly 0.59,reflecting that PM2.5 was more important than coarse particulates in PM10 and should be pay more attention . |
