摘      要：Skadar Lake,the largest lake on the Balkan Peninsula,is famous for a wide range of endemic and rare,or even endangered plant and animal *** anthropogenic pressures have,however,influenced the fragile equilibria of the lake ecosystem,with metal pollution as one of the primary ***,this study investigated spatial distribution of metal pollutants in the water and sediment phase of Skadar Lake,and anthropogenic and environmental factors affecting this distribution.A sieving analysis showed that sediment in Skadar Lake is mainly distributed in the three smallest fractions(colloid,clay and silt).Eleven metals were analyzed in the lake surface and bottom water,and only six of them were detected:potassium,magnesium,calcium,nickel,aluminum and *** were all present at low *** contrast,sediments contained elevated levels of some metals with concentrations between 28.1-126.8 mg kg-1for Ni,23.6-79.2 mg kg-1for Cr,9.2-36.9 mg kg-1for Cu,199-878 mg kg-1for Mn and 9.6-23.1 g kg-1for *** exceeded consensus-based guidelines for safety towards freshwater dwelling *** organic matter content of the sediment fluctuated between 4.7 and 21.5%.No correlations were found between metal concentrations,organic matter and sediment particle size fractions,suggesting that the latter are not the main factors controlling metal accumulation in Skadar Lake.
