The nickel smelters in northwest-Russia emit large quantities of sulphur dioxide (SO2) and heavy metals. These emissions lead to enhanced concentrations of environmental pollutants in the border areas. The monitoring programme shows that air quality in the border areas was in compliance with Norwegian critical levels for SO2 for the calendar year 2019, as well as for seasonal mean for winter 2018/19. In January 2019, there were two episodes with elevated concentrations of SO2 at Svanvik. At 25 January 2019, the local population was notified by SMS. Target values for Ni and As were met.
