为监测安庆城区“无车日”活动当天和前后时段的环境质量变化状况，在机动车辆活动量大、人群密度高的区域设置监测点，以大气中可吸入颗粒物PM10、氮氧化物NOx 和道路交通噪声作为监测项目.结果表明，通过“无车日”活动，大气环境和声环境有明显的改善，城区PM10值下降率为31.6%，主要交通干道交通噪声下降了1.0~4.0 dB（A).
為鑑測安慶城區“無車日”活動噹天和前後時段的環境質量變化狀況，在機動車輛活動量大、人群密度高的區域設置鑑測點，以大氣中可吸入顆粒物PM10、氮氧化物NOx 和道路交通譟聲作為鑑測項目.結果錶明，通過“無車日”活動，大氣環境和聲環境有明顯的改善，城區PM10值下降率為31.6%，主要交通榦道交通譟聲下降瞭1.0~4.0 dB（A).

To compare and analyze quality difference of atmospheric environment between “car day” and “car free day” in Anqing, the monitoring spots were set at the crowded road section in stream of the people and vehicle for collecting data, including inhalable particulate matter PM10 , concentration of nitrogen oxide NOx as well as traffic noise. The results showed that atmospheric quality and sound environment were improved obviously by carrying out“car free day”. Hereinto, the valve of PM10 in urban area and traffic noise of the main road was decreased by 31. 6% and 1. 0~4. 0 dB(A) respectively.
