Klimatstyrda sulfidoxidationer som orsak till surhet och höga metallhalter i vattendrag i norra Sverige
This study about existence, causes and effects of oxidations in sulphide-bearing sediments in the coastland of northen Sweden is based upon an unique waterchemical sample program during 1990-2007 including the following parameters: pH, alkalinity, colournumber (mg Pt/l), COD (Chemical Oxygen Demand)...
