State of the Environment
State of the environment
The state of the environment in the Inari – Pasvik River area is mostly affected by the emissions of industry in the Kola Peninsula, such as acidifying sulfur compounds and heavy metals that are detrimental for the environment.Pollutants are dispersed around the various regions of the border area in different ways depending on the prevailing winds, flow direction of water and the distance from the emissions’ source. The most polluted area is the immediate vicinity of the emission sources, where significant quantities of sulfur dioxide and heavy metals have almost entirely destroyed the vegetation over the years. This industrial wasteland that has formed in the impact area of emissions covers hundreds of square kilometres. Prevailing winds mainly disperse airborne emissions to a north-easterly direction. Sulfur dioxide emissions have significantly reduced over the last 20 years. Nevertheless, in some parts of the border area the sulfur dioxide concentrations are unreasonably high. In the town of Nikel, in the heart of the emissions’ sources, sulfur dioxide concentration in the air is three times greater than the permitted threshold value. Heavy metal emissions have not fallen at all, and based on the deposition measurements conducted in Norway, these emissions may have even increased recently. Acidifying sulfur compounds reduced The environments in different regions react in different ways to acidic deposition. The first signs of improvement in water quality can be seen in some lakes of the Vätsäri and Jarfjord areas that are naturally sensitive to acidification.
Acidification means that soil or water bodies are losing their capacity to neutralize (buffer) acidic deposition.Acidifying compounds are deposited with rain as wet deposition or with particles and gases as dry deposition.
