The nickel smelters in northwest-Russia emitted 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 2020, as well as for seasonal mean for the winter 2019/20. The smelter in Nikel ceased operation on 23 December 2020. This will give less pollution in the border areas in the future. Target values for Ni, As and Cd were not exceeded.
