Abstract

The Lake Shkodra - River Buna wetland complex (Albania) is included in Ramsar sites and is one of the most important on the Adriatic coast. Dissolved organc carbon (DOC), particulate organic carbon (POC), surface active substances (SAS), copper complexing capacity (CuCC) and polymeric organic material containing nitrogen atoms (N-POM) were measured in the area. DOC concentrations were in the range 0.335-4.535 mg CL-1, while POC was in the range 0.010-4.147 mg CL-1. SAS concentrations expressed as equiv. of Triton-X-100 were in the range 0.083-0.302 mg T-X-100 L-1 . CuCC values were in the range 110-758 nM Cu2+.The measured concentrations are increased only for certain sites (e.g. lagoon site, B1), where the highest DOC, POC and SAS were measured. At these sites polymeric organic material (N-POM) was measured.. Normalized surfactant activity values (NSA) determined showed that the organic material present in the this aquatic system is similar in adsorption properties to the model fulvic acid and protein albumin.
