[Present state of the Moraca river [Montenegro, Yugoslavia] water quality
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.

Phytoplankton as indicator of the Tisza river [Serbia, Yugoslavia] pollution
2001
Brankovic, D. | Budakov, Lj. (Zavod za zastitu prirode Srbije, Novi Sad (Yugoslavia). Odeljenje u Novom Sadu)
The paper deals with the results of the phytoplankton investigations carried out in the 7 localities along the Yugoslav section of the Tisza river in the period of 13 Februar - 3 March 2000, after accidental pollution with the cyanide and heavy metals. Although certain decrease in the density of the phytoplankton and variation in the qualitative and quantitative composition were recorded, there are no significant differences in comparison with the data before accident. The short-term and possible long-term consequences were recognized, having in mind ability of algae to accumulate pollutants into their cells, and that algae are the first link on food chains. Since the content of pollutants increases with every next member in the chain, it is easy to assume cumulative effect of the all previous members.

Maljevic, E. | Despotovic, N. | Vasiljevic, M. | Stupar, M. (Institut za zastitu zdravlja Srbije "Dr Milan Jovanovic - Batut", Beograd (Yugoslavia))
In this paper a part of results of the wastewater quality control from the Thermal Power Plant "Kostolac", water from the rivers Danube and Mlava, and groudwaters near by (Serbia, Yugoslavia), is considered. In order to protect environment from the effects of hurtful substances make during working process of Thermal Power Plant "Kostolac" is especially does using solid fuel (coal), the Institute of Public Health of Serbia following an approved program checks upon the quality of groundwaters, water the rivers Danube and Mlava including the wastewater from the Thermal Power Plant "Kostolac", four times a year. The results of our research point out to the hurtful effects of the wastewater from Thermal Power Plant "Kostolac" on the groundwater.

Teodorovic, I. (Univerzitet u Novom Sadu, Novi Sad (Yugoslavia). Prirodno-matematicki fakultet, Institut za biologiju) | Djukic, N. | Dalmacija, B. | Maletin, S. | Miljanovic, B. | Bokorov, M.
To evaluate precision and reliability of recently introduced Metal Pollution Index as a method for metal pollution monitoring of surface waters, a series of toxicity tests with Daphnia magna have been undertaken. The sampling sites (the River Danube wetlands and Hydrosystem DTD (Danube - Tisza - Danube), Serbia, Yugoslavia) for this study have been chosen according to previously recorded high MPI values. Chemical characterization and WET (whole effluent toxicity) testing of selected waste waters at the chosen sampling sites, and the recipient water toxicity testing upstream and downstream the discharger evaluated the validity of MPI, and, on the other hand, discriminated the effects of background pollution. The results of acute and chronic toxicity tests of water and sediment corresponded well with MPI values, which leads to a conclusion that MPI could be regarded as a reliable and precise method for metal pollution monitoring of surface waters.

Sapromicrobiological aspect of the water and mud quality of the most polluted sector (Bezdan-Bechey) of the main canal of the DTD [Danube - Tisza - Danube] canal net [Serbia, Yugoslavia]

Gajin, S. (Prirodno-matematicki fakultet, Novi Sad (Yugoslavia). Institut za biologiju) | Matavulj, M. | Petrovic, O. | Radnovic, D. | Simeunovic, J.
As a result of this study the overload by pollutants and low quality of canal water in the zone downstream of Vrbas and Srbobran towns (Serbia, Yugoslavia) has been recorded. Regarding to started work on demudification of canal bottom in the industrial zone of Vrbas town, in the course of 2000 the additional investigations of mud profile downstrean of wastewater discharge into the canal have been done. In the investigated mud samples the extremely high number of organotrophic bacteria was found (up to 1.7 x 10**10 cfu/ml), but also high number of conditionally pathogenic bacteria (opportunistic bacteria) was recorded. Also, the high number of fecal (thermo-tolerant) coliform bacteria (Escherichia coli and Klebsiella - Enterobacter - Citrobacter group of bacteria), as well as the presence of colifags was found. Such findings indicate possible bad consequences to the health of humans contacting this mud, as well as to the ground water quality, indirectly, via drainage water.
