Open publisher page 3 citations

Abstract

Based on analysis of sediment and water samples of Changdang Lake, results showed that pollution load of COD, TN and TP, which were released from sediments, accounted for 16%, 25% and 21% respectively of the total pollution load importing into the Lake. As a result, eutrophic status of the Lake was deteriorating in recent years. The water in west and south part was in eutrophication status, and TN, TP in centre of lake increased obviously. To control eutrophication, some countermeasures were proposed to protect the Lake.
