Air pollution by sulfur dioxide

Higher concentrations of sulfur dioxide (SO₂) can have especially negative effects on the respiratory tract; asthmatics and people with chronic respiratory diseases are particularly at risk. SO₂ is toxic to plants. It is also an important precursor for the formation of acid precipitation and secondary particulate matter. Sulphur dioxide emissions are produced by the combustion of sulfur-containing fuels and by some industrial processes. The time series shows the modeled maps of the annual mean values since 1980 in a 200 m grid, and in a 100 m grid from 2020. The SO₂ concentrations may deviate locally from the modeled data. Individual pixels should not be used to evaluate individual locations. The annual limit for SO₂ set in the Ordinance on Air Pollution Control is 30 µg/m³.
