Abstract

Abstract The paper highlights the contribution of the road traffic to PM 2.5 air pollution, taking in consideration the atmospheric parameters. But, despite other studies, temperature and relative humidity are considered as moderating variable. The concentration of particulate matter is also influenced by local geography, urban structure, and streets shape. The case study was done in Bucharest, in an open area. The PM 2.5 air concentration time series is proved stationary, an autoregressive model with two lags being tested. While the main effects of road traffic and humidity are significant, temperature has not a significant direct effect. But both moderators show interactive effects. The conditional effects are getting down with increase in temperature and humidity, due to changes in air dynamics and precipitation phenomena.
A大气条件对PM2.5交通相关浓度的调节作用
摘要本文在考虑大气参数的情况下,重点分析了道路交通对pm2.5大气污染的贡献。但是,尽管有其他研究,温度和相对湿度被认为是调节变量。颗粒物浓度还受当地地理、城市结构和街道形状的影响。案例研究是在布加勒斯特的一个开放地区进行的。证明了pm2.5空气浓度时间序列是平稳的,并检验了一个具有两个滞后的自回归模型。虽然道路交通和湿度的主要影响是显著的,但温度没有显著的直接影响。但两个主持人都表现出互动效应。由于空气动力学和降水现象的变化,条件效应随着温度和湿度的增加而减弱。
