| 摘 要： | 对济南市环境空气中PM2.5中碳组分污染特征的研究结果表明,济南市环境空气细颗粒物中碳主要以有机碳(OC)和元素碳(EC)的形式存在,二者浓度以冬季最高,且变化趋势相同;OC占总碳比例较高;冬季二次有机气溶胶(SOC)浓度最高,与污染源排放及气象条件有关。

| Abstract: | The analysis results of pollution characteristics of PM2.5 in Jinan atmosphere show that the carbon in particles PM2.5 in atmosphere exists in the form of OC which has a higher proportion and in the form of EC.The concentrations of OC and EC reach the highest level in winter and with the same trend.The concentration of SOC is highest in winter,which relates with the pollution sources and meteorological condition. |
