摘要
近年来雾霾严重影响到了人们正常的生活和身体健康,许多报道都将机动车尾气看做是雾霾的"元凶"。G20期间,在柯桥区及周边区域几乎全部企业都处于停产状态下,根据柯桥区域机动车限行前后的数量与空气报告得出的数据显示:PM2.5浓度没有随着机动车减少而降低,汽车的尾气对PM2.5浓度的影响有限,机动车尾气是雾霾的"元凶"的说法有些言过其实。
Nowadays haze seriously affects people＇s normal life and health. Many reports consider motor vehicle exhaust as the cause of haze. During the G20 period, almost all enterprises in Keqiao district and the surrounding area are in shutdown. According to the Keqiao area of motor vehicle number and air report data show： PM2.5 concentration does not decrease with the reduction of motor vehicles. Vehicle exhaust has limited impact on PM2.5 concentration. It＇s exaggerated to say motor vehicle exhaust is ＂culprits＂ for haze.
