Plantago subulata is a facultative serpentinophyte, with predominantly ultramafic distribution in Serbia and Montenegro. The plant samples were collected from ultramafic and non-ultramafic substrate, including two abandoned mining sites, with the aim to assess the accumulation potential of this species. The samples were collected from 10 sites in Serbia and Montenegro and element concentrations in plants and soils were determined. Particularly high concentrations of Fe, Cu, Mn, Zn, and Cd were found in the soil and plant samples from an abandoned iron mining site, Mt. Kopaonik, Suvo Rudište. The concentrations of Ni, Cr, Fe, Co, and Cd were statistically different between soil and plant samples from ultramafic and non-ultramafic bedrock. Considering the fact that concentrations of Zn, Ni, and Cr in roots and shoots were positively correlated with their respective contents in the soil, i.e., the chemical composition of the plant and soil samples reflected the characteristics of the substrate, and for most of the elements analyzed, P. subulata acted as indicator species. For Cd and Pb, only the root concentrations were positively correlated with soil content, indicating exclusion and root sequestration as the main tolerance strategies for these elements. Although below the hyperaccumulation threshold, a strong accumulation capacity of P. subulata was found for Ni and Cu.

2003
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.
Mostrar más [+] Menos [-]Physical and chemical properties as well as the contents of dominating ions in spring waters of Zlatibor region [Serbia, Serbia&Montenegro] whose capacities and locations may satisfy the requirements for their bottling
2003
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.
Mostrar más [+] Menos [-]Eutrophication and bacterial pollution of the Montenegrian coastal sea during 2002
2003
Regner, D. | Vuksanovic, N. | Stjepcevic, B. | Joksimovic, D. (Institut za biologiju mora, Kotor (Serbia and Montenegro))
In this paper, results of seasonal investigations throughout 2002, important for evaluation of the eutrophication and bacterial pollution of the Montenegrin coastal sea were presented. It was established that the difference between warmer and colder periods of the year was highest in the part of the Montenegrin coastal sea exposed to the strongest impact of the open waters of the Southern Adriatic.
Mostrar más [+] Menos [-]Non-conventional water treatment techniques prior slow sand filtration
2003
Ljubisavljevic, D. | Jovanovic, B. (Univerzitet u Beogradu, Beograd (Serbia and Montenegro). Gradjevinski fakultet)
Slow sand filtration is an effective water treatment process. However, the performance of slow sand filters is influenced by the raw water turbidity. Filtration on pebble-matrix and roughing filters is introduced as a process effective in reduction of raw water turbidity. Efficiencies of these pretreatments documented on the raw water sources world-wide are presented in this paper as well as the investigation results from the similar raw water source in Serbia (Serbia&Montenegro).
Mostrar más [+] Menos [-]Phenol removal from industrial waste waters by horseradish (Cochlearia armoracia L.) peroxidase
2003
Nedic, L. (Strucna skola "Sveti Sava", Bujanovac (Serbia and Montenegro)) | Stanisavljevic, M.
This paper presents a process for phenol removal comprising a reaction step in which phenol is polymerized in the presence of an enzyme horseradish peroxidase. A crude preparation from horseradish roots was used as a low purity source of the enzyme. The technical feasibility of the process was studied using 1 to 10 mM synthetic phenol solutions. Experimental results showed the potential of the proposed technique. A phenol conversion higher than 90% was observed at the polymerization process.
Mostrar más [+] Menos [-]Water potential of Sasko lake with the goal of aquacultural development [Montenegro, Serbia&Montenegro]
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.
Mostrar más [+] Menos [-]Capability for utilization of terrace deposits for water supply of Nis Tobacco Factory [Serbia, Serbia&Montenegro]
2003
Radenkovic, Z. (Institut za vodoprivredu "Jaroslav Cerni", Beograd (Serbia and Montenegro)) | Jevtic, G. | Josipovic, J. | Jevtic, O.
Nis Tobacco Factory, Serbia (Serbia&Montenegro) has water supply from two resources, public water supply system and from its dug well. In periods of water shortages and smaller deliveries from public water supply system (e.g. recession periods) it is necessary to provide additional water quantities for proper functioning of tobacco refinement. For that purpose capability for utilization of terrace deposits for water supply was analyzed.

2003
Damjanovic, M. | Babic-Mladenovic, M. (Institut za vodoprivredu Jaroslav Cerni, Beograd (Serbia and Montenegro))
Regular monitoring of water quality of the Danube river in the backwater zone includes analysis of the sediment. It is well known that sediment is a sink place for the non degradable compounds and it reveales the long term water quality status in the reservoir. This paper presents the general results on the Iron Gate reservoir siltation. as well as some data regarding pollution level, based on investigations carried in the period of 2001-2002. The investigations included organic load of the sediment, heavy metals and organic pollutants content. The degree of pollution is evaluated on the basis of various criteria, also compared to results of previous case studies.
Mostrar más [+] Menos [-]Good water supply for the "Crni Lug" hunting area [Serbia, Serbia&Montenegro] present state and future facilities
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.
