| 摘 要： | 采用特征性化合物法和统计法相结合的方法,对上海市大气中非甲烷烃(NMHC)与作为机动车尾气特征性化合物的CO与Pb进行了相关性分析。结果发现,NMHC与Pb在显著性水平0.01下显著性相关,相关系数达到0.593(n=18);NMHC与CO小时均值相关系数达到0.495(n=2329),日均值相关系数达到0.581(n=114)。从而判断机动车尾气排放已经逐渐成为上海市大气中NMHC的主要贡献者。

| Abstract: | Relationship between non-methane hydrocarbons (NMHC) in ambient air and vehicle exhaust emission in Shanghai has been studied through determining the correlation between NMHC and CO and Pb which can be regarded as the characteristic compounds of vehicle exhaust emission. Significant coherence between NMHC and Pb, and NMHC and CO reached 0.593 (a=18) and 0.495 (n=2329) respectively, which suggested that vehicle exhaust emission be more responsible for higher NHHC in ambient air in Shanghai |
