Waste treatment causes dust and odours that, depending on the weather conditions, can spread to the surrounding area. We monitor total reduced sulphur (TRS) compounds, thoracic particles (PM10), fine particles (PM2.5), and weather conditions at two monitoring sites in the area of the Ämmässuo eco-industrial centre. The results are available as a graph or table. The tabs allow you to select which monitoring results you want to view. The monitoring results are displayed hourly. You can select a day, week, or month as the reference period. The monitoring results are unverified hourly averages.
