The concentrations of the measured components are generally low and below national limit values for the protection of human health and critical levels for the protection of vegetation. Wind from northern sectors gave the highest average concentrations of nitrogen oxides and sulphur dioxide, which indicates the power station and the harbour as possible sources. The measurement results for CO2 show an annual variation with higher concentrations in the winter and lower in summer. Measured concentrations of CO were most likely caused by local snowmobile traffic.
