Sources of Copper and Zinc to the aquatic recipients of Stockholm
(English)Manuscript (preprint) (Other academic)
A budget is presented for Cu and Zn in the aquatic surroundings of Stockhohn. The results indicate that the sediment deposition of Cu in the area studied approximately balances the sources. For Zn, there seems to be a net export from the area to the open Baltic Sea. The regional background is the dominating source for both metals. Among the anthropogenic sources sewage treatment plants and storm water were found to emit considerable amounts. The origin of Cu and Zn to sewage and storm water was therefore studied. Tap water, brake linings and copper roofs were found to be the major sources of Cu to the recipient, and for Zn the main sources are galvanized goods and tyres. Food wasfound to be a considerable source relating to both metals.
