Bente Christiansen Sammendrag / Summary This screening study of POPs in bottom sediments carried out in the Paz watercourse reveal higher levels of all environmental contaminants studied in the bottom sediments from Lake Kuetsjarvi. There was a clear trend that the contamination levels decreased with increasing distance from the smelters. The levels of PCB and DDT in sediments from the Paz watercourse were high compared to levels measured in surface sediments from other lakes in Northern Norway. There was no clear trend on the distribution of PBDE in the Paz watercourse compared to the reference lakes. It is strongly recommended that POPs in sediments are included in future monitoring_programmes.______________ Emneord: Key words: Pasvik vassdraget Paz watercourse Sedimenter Sediments Milj 0 gifter Contaminants PCB PCB Prosjektleder / Project manager Kvalitetskontroll / Quality control f lilc tX L U ^ r v c x d r Tatiana Savinova Anita Evenset © 2007 Akvaplan-niva Oppdragsgiveren har lov a kopiere hele rapporten til eget bruk.
