The influence of active substance of detergents in the sea water to the fish activities
1998
Milosevic, I. | Kovacevic, A. | Kovacevic, N. | Gojkovic, M. | Rakic, Lj. (Institut za biologiju mora, Kotor (Yugoslavia))
In this work influence of different concentrations of linear active substance (LAS-DBS) on activity of Serranus scriba CUV have been studied. Desynchronization of circadian rhythms is in direct correlation with LAS growing concentrations. The high disproportion was found between maximum permitted concentrations (3 mg/l) and our results which show the changes in fish behaviour at 0.2 mg/l LAS.

2001
Vukcevic, S.V. (Institut za tehnicka istrazivanja, Podgorica (Yugoslavia))
Paper points the present water quality of the Moraca river (Montenegro, Yugoslavia), from rivermouth of Zeta to Skadarsko jezero lake. Hydrological analysis, level of water pollution are also presented, together with proposed water quality protection measures regarding the Yugoslav federal regulations for surface waters.

Djuraskovic, P. | Tomic, N. (Republicki hidrometeoroloski zavod, Podgorica (Yugoslavia))
The balance of production and respiration processes in water of Crnojevica river (Montenegro, Yugoslavia) has been estimate, over the estimate correlation between significant parameters of water quality (BOD, % saturation of O2, pH). Correlation between these parameters is established. The balances exist in stationary conditions. But, impact of precipitation is disturbing this state. The hydrodynamic conditions at underground flow and wastewater effluent from the town Cetinje area, has been influence for it, too. The data are referring to small and middle water state.

Possibilities for mapping pollution in rivers within their basins
1997
Brajkovic, M. (Institut za vodoprivredu "Jaroslav Cerni", Beograd (Yugoslavia)) | Gavrilovic, Z. | Vukmirovic, M. | Dakovic, S.
Problems encountered in evaluating surface water quality arise from the requirements of relevant regulations that these evaluations should be made in the last favourable hydrologic conditions during design flow rate (required minimum flow). However, the major part of measurements of water quality parameters is not performed under such conditions and the result must be corrected for the conditions under required minimum flow. Two possible approaches to solving this problem are presented in this paper and explained using an example of the Juzna Morava river basin up to the Station Korvingrad, Serbia (Yugoslavia). This basin is unhomogeneous regarding its hydrologic characteristics and mass flow of pollutants. The results of analysis are presented in the cartography form using the GIS technology.

1997
Buzarov, D. (Univerzitet u Novom Sadu, Novi Sad (Yugoslavia). Prirodno-matematicki fakultet, Institut za hemiju) | Vojinovic-Miloradov, M. | Pavkov, S. | Macvanin, N.
The monitoring the content of organochlorine insecticides and polychlorinated biphenyls in heterogeneous system of water-sediment is of a primary interest for the researching of contamination of the aquatic ecosystem because of high bioconcentration factors of these compounds and their bioaccumulation in flora and fauna of the aquatic basin. The sampling of water and sediment were done in the Boka Kotorska Bay (south Adriatic Montenegro Seaside), and estuary Bojana - Ulcinj, Montenegro (Yugoslavia), in AuTumn of 1995. The residues of organochlorine insecticides and polychlorinated biphenyls were determined by gas chromatography, Varian 3400 with capillary columns OV-101, length 25 m, with ECD. The residues of isomers of HCH (hexachlorocyclohexane), DDT and PCB (polychlorinated biphenyls) were identified in all investigated samples.

1997
Vulic, D. (Institut za vodoprivredu "Jaroslav Cerni", Beograd (Yugoslavia)) | Cukic, Z. (Univerzitet u Novom Sadu, Novi Sad (Yugoslavia). Prirodno-matematicki fakultet, Institut za hemiju)
Owing to the habit of most of Yugoslavs to prepare coffee without filtering, the large part of used coffee comes to recipients. In this paper, the influence of coffee deposits reaching recipients in Yugoslavia is analyzed. Results of laboratory examination of the biodegradability and kinetic of biodegradability of coffee deposits are also presented.

1997
Djuraskovic, P.N. | Pejovic, M. (Republicki hidrometeoroloski zavod, Podgorica (Yugoslavia))
The river Tara (Montenegro, Yugoslavia) is under the treatment of the international (UNESCO) and domestic legal protection, so the prescribed quality of its water is the 1st class. Permanent measurement of the water quality of this river shows that due to the influence of the human factor, its quality has been endangered. Examination of the data collected through many years at all the measurement station along its current shows that the quality of water and pollution estimate have changed.

1997
Cukic, Z. (Univerzitet u Novom Sadu, Novi Sad (Yugoslavia). Prirodno-matematicki fakultet, Institut za hemiju) | Kilibarda, P. | Kojcic, K. | Jovanovic, D.
In this paper, the results of statistical analysis of then years water quality data of Tamis river at the Romanian-Yugoslav border ("Jasa Tomic" Control Station) are presented. Following changes of analyzed water quality parameters at the Romanian-Yugoslav border a strong trend of deterioration has been observed during analyzed period. Because of periodical accidentally high organic content (COD, BOD) and concentration of ammonia and organic nitrogen in river water, it is concluded that upstream discharging of farm waste waters was the main reason of deterioration of water quality along the Yugoslav part of Tamis river.
