Monitoring air quality
HSY's air quality monitoring sites continuously monitor air pollutants such as particulate concentrations. You can check the Helsinki Metropolitan area's air quality situation hourly at every monitoring site. In 2017, the temporary air quality measuring sites are located in Rekola, Olari, Mäkelänkatu and in the Helsinki Airport. The measurements serve to canvass air quality in areas of single-family housing, along the busy streets and in the impact area of the Helsinki Airport. Check where the monitoring sites are located.
