Sulphur dioxide - SO2

In 2008, the mean concentration of sulphur dioxide (SO2) measured during the winter period was higher than the mean annual concentration at all measuring points. Mean annual SO2 concentrations and mean winter period concentrations in excess of the limit values set for ecosystem protection were observed in major urban centres.

According to the available data, mean daily concentrations of SO2 in excess of the limit value were observed in the City of Skopje only in 1998, 1999 and 2006 due to the operation of facilities for heat and energy production in the winter period, industry and heavy traffic. Such exceedances, however, were not found in Macedonian cities.
