Sažetak
Increasing dissolved organic matter (DOC) in aquatic ecosystems can lead to disturb the balance, deterioration of the water quality, and a more expensive water purification process. As a significant part of the aquatic DOC, the environmentally relevant organic adsorbing compunds (OACs, amphiphilic/hidrophobic type), can impact on the both abiotic and biotic elements. In this study it was demonstrated that the no─expensive methodology can be used for the fast monitoring/evaluating water quality with respect to the content and the surface activity (i.e. hydrophobicity) of the DOC. This includes measurement of the total adsorption efect of OACs at the mercury electrode by electrochemical methods. The concept has been applied to rivers from the agricultural district (Sava and Lonja), and from the highly protected area (Krka as a part of National Park) as well as to the marine lake ecosystem (Rogoznica Lake).
