HEAVY METALS MIGRATION IN THE SYSTEM: NEAR-BOTTOM WATER – INTERSTITIAL WATER – BOTTOM SEDIMENT IN GARDNO LAKE
Journal Title: Baltic Coastal Zone - Year 2007, Vol 11, Issue 1
Abstract
The study of heavy metals concentration in the estuarine lake Gardno water and bottom sediments showed that the river Łupawa and periodic inputs of sea water exert decisive influence on forming of the water stores and bottom sediments quality in this lake. The largest concentrations of Cd, Cu, Mn, Pb and Zn were observed at river mouth into the lake region (Cd – 0.26, Cu – 3.71, Mn – 94.3, Pb – 10.01, Zn – 16.26 μg dm[sup]-3[/sup]) and the lowest at water outflow from the lake region (Cd – 0.13, Cu – 1.81, Mn – 53.8, Pb – 8.86, Zn – 8.05 μg dm[sup]-3[/sup]). Average concentrations of those metals in the lake water, suspension and bottom sediment form the following row: Mn>Zn>Pb>Cu>Cd. The contents of analysed metals were the highest in interstitial water, smaller in near-bottom water and the smallest in surface water. Average content of metals in near-bottom suspension was about 30% higher than that in surface suspension, but enrichment factors of those metals in suspensions do not show essential statistic differences. This probably results from continual mixing of water masses by wind. The migration coefficients indicated that bottom sediments of lake Gardno have large accumulation properties of heavy metals.
