摘　　要：以2020—2022年上海市闵行区70个道路扬尘在线监测点位监测数据为基础,同时结合同时段、同区域大气微站获取的可吸入颗粒物浓度、气象参数、环境统计纳管企业污染物排放量和车流量等数据,开展相关性分析,研究道路扬尘在线监测技术在大气环境质量监测中的应用,分析道路扬尘浓度变化,探索道路扬尘变化规律和主要影响因子。结果表明,道路扬尘在线监测数据具有较好的科学性和准确性,上海市闵行区道路扬尘浓度呈逐年下降趋势,春季与冬季高,夏季与秋季低,昼间高、夜间低。道路扬尘浓度变化与车流量、气象等因素较为密切,与环境统计企业废气污染物排放量无关。Based on the monitoring data of 70 online monitoring points for road dust in Minhang district,Shanghai city from 2020 to 2022,correlation analysis is conducted on the concentration of inhalable particulate matter,meteorological parameters,environmental statistics,pollutant emissions from enterprises,and vehicle flow obtained from atmospheric micro stations in the same region during the contract period,and the application of online monitoring technology for road dust in atmospheric environmental quality monitoring is studied,and the changes in road dust concentration are analyzed to explore the patterns and main influencing factors of road dust changes.The results indicate that the online monitoring data of road dust has good scientificity and accuracy,and the dust concentration on roads in Minhang district,Shanghai city has been decreasing year by year,with higher levels in spring and winter,lower levels in summer and autumn,and higher levels during the day and lower levels at night.The changes in road dust concentration are closely related to factors such as traffic flow and meteorology,and are not related to the emissions of exhaust pollutants from environmental statistics enterprises.
