| 摘 要： | 在广州市中山大学采样点进行了为期1年的大气细粒子(PM2.5)采样,监测分析得到PM2.5及有机碳(OC)、元素碳(EC)和水溶性有机碳(WSOC)等组分的质量浓度,并进行了比较和评价分析。结果表明广州市细粒子碳污染较严重。对OC、EC和WSOC质量浓度的月变化和季节变化特征进行了讨论,并分析了原因。OC、EC浓度相关性好,表明OC、EC来源大部分相同。根据OC/EC比值,估算二次有机碳(SOC)量,结果是SOC占OC的1/3。讨论了SOC和SOC/OC比值的季节分布,结果证明SOC夏季生成比冬季多。 |

| Abstract: | Daily PM2.5 samples were collected at Sun Yat-sen University in Guangzhou city,lasting 1 year.The loaded samples were weighted for PM2.5 mass concentration,and analyzed for organic carbon(OC),elemental carbon(EC),and water-soluble organic carbon(WSOC).Monthly and seasonal distribution characters of PM2.5 and OC,EC,WSOC were discussed and the results obtained in this study were compared with others,showing severe carbonaceous pollution in Guangzhou.OC-EC relationship was good,indicating most of sources of OC... |
