Atmospheric particulate matter and photochemical component network monitoring solutions

Program overview

Online source analysis of atmospheric particulate matter and photochemical components to facilitate collaborative management and control of PM₂.₅ and O₃

The atmospheric particulate matter and photochemical component network monitoring solution is based on the "14th Five-Year Plan National Capacity Building Plan for Fine Particulate Matter and Ozone Collaborative Control and Monitoring Network" (Environment Office Monitoring Letter [2021] No. 218) to monitor key areas for air pollution prevention and control, and VOCs emissions. Cities with high levels of ozone and excessive ozone will carry out collaborative monitoring of PM₂.₅ and photochemical components, improve the regional collaborative control and monitoring network, fully play the role of monitoring support and support, and assist the coordinated management and control of PM₂.₅ and O₃ in the region.

Solution application

The Beijing-Tianjin-Hebei region and surrounding areas, the Fenwei Plain (i.e., the seven provinces and cities of Beijing, Tianjin, Hebei, Shanxi, Shandong, Henan, and Shaanxi) and other cities where the annual average concentration of PM₂. , aerosol vertical distribution and other monitoring. Monitoring of VOCs components in ambient air will be carried out in key areas for air pollution prevention and control during the “14th Five-Year Plan”, cities with higher VOCs emissions and other cities with excessive ozone. Each city sets up monitoring points in high-ozone areas in densely populated urban areas; and based on ozone pollution characteristics and prevention and control needs in various places, monitor points in the city's upwind direction or background points, VOCs high-concentration points, O₃ high-concentration points and areas Add VOCs component monitoring points at impact edge monitoring points (downwind points). In principle, PM₂.₅ and VOCs components are monitored at the same point. Provincial ecological environment departments shall add regional transmission/rural monitoring points based on regional fine particulate matter and ozone pollution characteristics and transmission channel conditions, focusing on strengthening regional monitoring sites at provincial and municipal boundaries, especially the construction of major transmission channel area points. To analyze ozone transmission paths and patterns. Subsequent adjustments will be made appropriately based on collaborative control supervision needs.
