Bente Christiansen Sammendrag / Summary This screening study of POPs in fish (whitefish and pike) from selected lakes in the Paz watercourse reveals that the highest levels of almost all of the analysed contaminants were found in fish from Kuetsjarvi. The levels of POPs decreased with increasing distance from the smelters. Increased cytochrome P450 activity was found in fish from the Lake Kuetsjarvi compared to those in fish from less contaminated areas. PAH were the major contaminants in fish analysed. The levels of POPs in fish tissue did not exceed known Russian and International food quality criteria.
