摘要
在四个季节采样分析的基础上 ,本文报道了重庆市主城区江北区 (商住区 )和缙云山 (清洁对照点 )两个监测点总悬浮颗粒物质量浓度的空间分布和季节变化特征 ,同时利用热分解示差热导法元素分析仪测定了 TSP中的 OC和EC浓度 ,探讨了 OC和 EC含量并与北京相应功能区的 TSP质量浓度及其 OC和 EC浓度进行了比较。结果表明 :重庆市商住区和对照点 TSP年均质量浓度均小于北京市商住区和对照点 ;重庆市商住区 OC和 EC年均质量浓度高于北京市商住区 ,北京市对照点 OC和 EC年均质量浓度高于重庆市对照点。两个城市的四个监测点 OC/ EC年均值均大于 2 .0 。
Based on the analysis of the four season samples,this paper reported the spacial distribution and seasonal variation of the mass concentration of the total suspended particulate(TSP) in Jiangbei(residential zone)and Jinyun Mountain (background zone).By means of the element analyzer,the concentration of OC and EC in the TSP was measured and compared with the correspondence function zones of Beijing.The result indicated that the average value of the mass concentration of TSP of Jiangbei(residential zone)and Jinyun Mountain (background zone) of Chongqing lower than Beijing's ,respectively.Thge average value of the mass concentration of OC and EC of residential zone in Chongqing is higher than Beijing,but the average value of the mass concentration of OC and EC of background zone is lower than in Beijing.The ratio of OC and EC exceeded 2.0 in the four monitor sites of the two cities,this revealed serious secondary pollution in the two cities.
