| 摘 要： | 对北京市交通微环境(轿车内)、西三环和增光路等典型道路交通环境以及紫竹院公园非交通环境空气甲醛浓度进行监测分析,解析交通环境空气甲醛污染特征。结果显示:对于交通微环境存在早晚甲醛浓度暴露峰值。典型道路交通环境甲醛浓度明显高于非交通环境甲醛浓度,西三环中路测试甲醛平均浓度为对应时段紫竹院公园环境甲醛浓度的1.7倍。甲醛浓度与道路交通流量有着明显的正相关,不同类型道路甲醛时间分布规律与车流量的时间分布规律一致,呈现早晚峰值。

| Abstract: | Formaldehyde concentrations in micro-traffic atmospheric environment(car),typical road traffic environment such as West 3rd-ring Road and Zengguang Road,and non-traffic environment in Zizhuyuan Park were monitored and analyzed.The characteristics of formaldehyde concentration in typical traffic atmospheric environment in Beijing were analyzed.The results show that,there is evident morning peak and evening peak for formaldehyde concentration in micro-traffic environment.The concentration of formaldehyde for ... |
