Continuous management of the air quality

Each day on this website, the QPA posts fine particle (PM2.5) concentration data from its local monitoring station. The PM2.5 concentration reference standard is set out in the Clean Air Regulation (QLR Q-2, r 4.1). It takes into account monitoring site locations and the various potential sources of fine particles. 30 µg/m3 is the maximum 24-hour average concentration. More
