2017
Dollinger, Jeanne | Dagès, Cécile | Voltz, Marc | Laboratoire d'étude des Interactions Sol - Agrosystème - Hydrosystème (UMR LISAH) ; Institut de Recherche pour le Développement (IRD)-Institut National de la Recherche Agronomique (INRA)-Centre international d'études supérieures en sciences agronomiques (Montpellier SupAgro)-Institut national d’études supérieures agronomiques de Montpellier (Montpellier SupAgro) | Research and development project funded by the French Office for Water and Aquatic Bodies (ONEMA)
The performance of buffer zones for removing pesticides from runoff water varies greatly according to landscape settings, hydraulic regime, and system design. Evaluating the performance of buffers for a range of pesticides and environmental conditions can be very expensive. Recent studies suggested that the fluorescent dyes uranine and sulforhodamine B could be used as cost-effective surrogates of herbicides to evaluate buffer performance. However, while transformation mechanisms in buffers have been extensively documented, sorption processes of both dyes have rarely been investigated. In this study, we measured the adsorption, desorption, and kinetic sorption coefficients of uranine and sulforhodamine B for a diverse range of buffer zone materials (soils, litters, plants) and compared the adsorption coefficients (Kd) to those of selected herbicides. We also compared the global sorption capacity of 6 ditches, characterized by varying proportions of the aforementioned materials, between both dyes and a set of four herbicides using the sorption-induced pesticide retention indicator (SPRI). We found that both the individual Kd of uranine for the diverse buffer materials and the global sorption capacity of the ditches are equivalent to those of the herbicides diuron, isoproturon, and metolachlor. The Kd of sulforhodamine B on plants and soils are equivalent to those of glyphosate, and the global sorption capacities of the ditches are equivalent for both molecules. Hence, we demonstrate for the first time that uranine can be used as a proxy of moderately hydrophobic herbicides to evaluate the performance of buffer systems, whereas sulforhodamine B can serve as a proxy for more strongly sorbing herbicides.

Karajic, M. | Djurovic, D. (Institut za zdravlje Crne Gore, Podgorica (Serbia and Montenegro))
Presentation is dealing with data on raw and drinking water quality of water supply sources and water supply systems in Podgorica, Montenegro (Serbia&Montenegro). Special attention was paid to organic matter content, concentration of disinfectants and disinfection by-products. Average values of all parameters examined are below maximum permissible levels defined by regulations. That means that physical-chemical quality of water is excellent.

2003
Novevska, V. | Vasileska, A. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
Water quality analyses were performed on littoral water samples, collected on Lake Ohrid in 2002 (January, February, June, July, August and September). Several microbiological parameters were compared. The number of Escherichia coli, the number of organotrophic bacteria and the phosphatase activity index were measured. Samples were collected along the shore of Lake Ohrid, i.e. at the village of Pestani, at Hotel Metropol, in Ohrid Bay and at the lake inflow of River Velgoska. The results of the study show that the different parameters are not compatible in terms of water quality characterization. The differences found are discussed below.

Stevanetic, V. (Zavod za zastitu zdravlja, Uzice (Serbia and Montenegro))
Nowadays people increasingly use bottled water for drinking which makes bottling a very profitable business. The aim of this paper is better understanding of physical and chemical properties as well as the contents of dominating ions and microbiological purity of 13 spring waters existing on the territory of Zlatibor region (Serbia, Serbia&Montenegro) which according to its water capacity, its watershed features and good roads availability may be further explored for the purpose of water bottling.

2003
Mandic, S. (Institut za biologiju mora, Kotor - Dobrota (Serbia and Montenegro)) | Kljajic, Z. | Joksimovic, A. | Mickovic, B. | Hegedis, A.
Sasko Lake, with surface area of 3.4 square km and depth of about 8 m, is situated is southwestern part of Montenegro (Serbia&Montenegro), within the hydrosystem of Skadarsko Lake. During 2002 and 2003, seasonal dynamics of main hydrographic, physical, chemical and biological parameters of this ecosystem was monitored. Reference measuring spots are defined, and in these places all future monitoring of system state will be accomplished. Also done are the preliminary batimetric measurements and maps of spaces suitable for development of breeding activities. In order to develop aquaculture as a strategic interest of Montenegro (Serbia&Montenegro), it is necessary to utilize these important potentials and place this important natural resource in full fuction. Included are the list of all fish species living in the lake, as well as the suggestion of species that could be suitable for commercial breeding.

2003
Timotijevic, V. ("Vodovod i kanalizacija" JKP, Kragujevac (Serbia and Montenegro)) | Djuran, D. | Milovanovic, D. | Comic, Lj. | Curcic, S.
Water reservoir "Gruza" is used forthe water supply of the town of Kragujevac and it's surroundings. The paper shows a comparative overview of physical, chemical and microbiological parameters during the period of 1987-1989, and 1997-1998. Variations of physical, chemical and microbiological parameters are given in the paper.

2003
Nikic, Z. (Univerzitet u Beogradu, Beograd (Serbia and Montenegro). Sumarski fakultet)
The fenced hunting area "Crni Lug" near Progar (Serbia, Serbia&Montenegro), included swamp tracts that have been drying. A natural environment of free game has changed over the last fifteen years. The unfavourable hydrological trend is explained by the antropogenic factor active in the hunting area and beyond it. The prevailing hydrogeological situation is interpreted and steps for rehabilitation of marshes are recommended. One of the emphsized goals is the supply of good water for animals throughout the year. Favourable hydrogeology and construction of adequate facilities in the hunting area will suffice for the revival of all activities related to water: flood control, agriculture, water supply, and hunting as a particularly profitable activity.

2003
Comic, Lj. (Prirodno-matematicki fakultet, Kragujevac (Serbia and Montenegro)) | Curcic, S. | Ostojic, A. | Milosevic, S.
Comparative analysis of results obtained in hydrobiological research conducted to date indicates that relatively few water reservoirs in Serbia have been subjected to complex hydrobiological investigations. Apart from the fact that hydrobiological investigations are now performed on only a small number of water reservoirs in Serbia, they are moreover inadequately coordinated, which is especially evident in differences of procedural approaches employed. With adoption of the principles of modern limnology and wider use of new criteria for water classification (m WQI for instance), the current state of hydrobiological research constitutes a basic for the development of comprehensive program of planned continuous studies of water reservoirs in Serbia resulting in their rational and successful management.

2003
Lokoska, L. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
During 2001, water from river Cerava and from the littoral where the river flow into lake Ohrid, were examined. Bacteriological analysis included ecological and sanitary aspekt of water state. Heterotrophic, proteolytic, amylolytic and phosphomineralizing bacteria, most probable number of total coliforms (MPN) and presence of Escherichia coli and Clostridium perfringens were determined. The results of investigations shows organic and faecal pollution and permanent negative anthropogenic effects.
