Sažetak
Organic ligands present in natural waters consist of largely uncharacterized macromolecular organic material, resulting from the combination of biological (phytoplankton and bacterial activity) , geochemical activities (humic and fulvic material) and pollution.The organic matter is partly identified and classified into into particular group of compounds such as carbohydrates, amino acids, proteins, fatty acids, lipids and hydrocarbons. A part of these organic ligands , exibit the property of surface activity, i.e the accumulation on different phase boundaries ( air/water ; water/sediments ; water/ biological membranes). Organic ligands capable of complexing copper ions were measured in the rain water in the coastal area of Adriatic, selected microlayer samples from Mediterranean coastal waters of France and of the north Norwegian sea, in the bulk and pore water samples of the coastal Aegean Sea as well as in the culture of macroalgae Ulva rigida . The relative concentration of the complexing ligands will be discussed as well as their abundance regarding part of dissolved organic carbon concentration (DOC) which exibit surface active properties (SAS). On that way the contribution of the different pools of ligands capable to complex Cu ions could be determined and discussed regarding the fate of both ligands and copper ions in these selected environments of the coastal seas.
