Pasvik River Watercourse, Barents region: Pollution Impacts and Ecological Responses Investigation in 1993
For the Pasvik River watercourse two major ecological problems was encountered: 1) Effects of heavy metals. This process is observed especially in Keutsyarv and to a lesser extent in lower part of Pasvik River. This is caused by the Ni and Cu input with waste water from smelters and pits of the &quo...
