TSP在线监测技术在道路扬尘监测的应用研究

Analysis on Application of TSP On-line Monitoring Technology in Road Dust

本文对比分析了杨浦区大气环境PM10、道路大气降尘和TSP在线监测结果数据月度均值差异,并结合新冠肺炎疫情影响对TSP在线监测数据周内日均值和小时均值规律进行探讨分析。结果表明,TSP在线监测技术能够很好地反应道路扬尘的区域性、季节性变化趋势特征,并且能够科学及时反映出居民出行频次、环境污染物总量等因素对道路扬尘量的波动影响,海量动态数据在道路扬尘治理工作中具有重要的参考价值。

This paper compares and analyzes the monthly mean value difference of PM10, road atmospheric deposition and TSP online monitoring results in Yangpu District, further research of daily average values in week and hourly average values in day of on-line data, discusses the influencing factors of road dust combined with the impact of COVID-19 epidemic. The results show that TSP online monitoring technology can reflect the regional and seasonal trends of road dust,also nicely display the fluctuation of road dust by the frequency of residents’ travel and the total amount of environmental pollutants. The massive dynamic data has important reference value in road dust control.
