中文摘要:
      通过比较2015年上海市5个交通空气质量监测点与附近环境监测点的监测数据,分析该市交通路边空气污染特征。结果表明:上海市交通空气污染水平总体高于环境站点,特别是黑碳(BC)、非甲烷总烃(NMHC)和苯系物(BTX)等特征污染因子;常规污染物及BC和BTX等特征因子均表现为冬季高于夏季;交通站NOx浓度明显高于环境点位,早晚高峰非常明显;交通站点的BC和BTX日变化的早晚高峰趋势比环境站点更加显著。
英文摘要:
      The characteristics of air pollution by the roadside in Shanghai were analyzed according to the air quality data from 5 traffic monitoring sites and nearby sites during 2015. The results showed that air pollution in the traffic sites were overall more severe than that in the environment sites. Especially, black carbon (BC), NMHC and BTX were the specific pollution factors. The concentration of normal pollutants, BC, BTX ect. were higher in winter than that in summer. The concentration of NOx in the traffic sites were higher than that in the environment sites. Peak time appeared obviously in the morning and at evening. BC and BTXs diurnal variation and peak feature at rush time in traffic sites were more significant than that in the environment sites.
