Saprobiological evaluation of the river Banja and it's tributary Pocibrava [Serbia, Yugoslavia] by the use of macrozoobenthos as indicator
1997
Markovic, Z. (Univerzitet u Beogradu, Beograd (Yugoslavia). Poljoprivredni fakultet) | Miljanovic, B. | Mitrovic-Tutundzic, V.
There were estimated of water quality of the river Banja and its trubutary Pocibrava, Serbia (Yugoslavia), during the period 1991-1994 by seasonal investigations of benthos fauna composition as bioindicators. The results have shown higher diversity of the Pocibrava bottom fauna community (66 taxa) than in the river Banja (53 taxa) where it was more uniform. Both water flows were receiving some organic loading and by the use of macrobenthos indicator organisms it was concluded that they belong to beta-mesosaprobic water quality class.

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.

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.

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.

2001
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.

Pavlovic, D. | Vukmirovic, V. (Univerzitet u Beogradu, Beograd (Yugoslavia). Gradjevinski fakultet, Institut za hidrotehniku)
Low flows are a good measure of the waste water recipient self-purification capability. The regional statistical analysis is an objective way of assessment of the required low flows. This paper presents the principles and key phases of the regional statistical analysis. The advantages of this method are a reduction of the outliers influence and the assessment of low flows on ungauged streams and stream profiles. The method is illustrated with the results obtained by the required low flows regional statistical analysis in Serbia (Yugoslavia) with 59 hydrological gauge stations in the scope, which data has the same length of 39 years, from the year 1956 to 1994.

1997
Rankovic, B. | Simic, S. (Prirodno-matematicki fakultet, Kragujevac (Yugoslavia). Institut za biologiju)
During hydrobiological investigations of the river Dulenska (Serbia, Yugoslavia) in June 1996, algological samples were taken at this river. In the algae community are found 34 taxa from two divisio: Bacillariophyta (28) and Chlorophyta (6). While qualitative composition of the algae colony was relativelly uniformed quantitative one was changeable along the course of the Dulenska river. By saprobiological analysis, it was found that the quality of water was changing along the course of the river. At the upper and middle course of river the water belonging to the second class. At lower course of the river (below Rekovac) water quality was getfing worse and it belonging to the third class.

Vukmirovic, V. | Petrovic, J. | Lazic, R. (Univerzitet u Beogradu, Beograd (Yugoslavia). Gradjevinski fakultet)
Drought characteristics (minimum flows, drought duration and volume deficit) of the Moraca river near Podgorica, Montenegro (Yugoslavia) are analyzed using the peaks over threshold method based on renewal processes. It is also shown that volume deficit and drought duration are highly correlated.

1997
Maljevic, E. | Stojanovic, Z. (Republicki hidrometeoroloski zavod Srbije, Beograd (Yugoslavia))
The paper provides experimental results of testing the content of heavy metals, and other harmful and dangerous matters of the Sava river sludge (Serbia, Yugoslavia). The testing carried out by the Republic Hydrometeorological Service of Serbia (Yugoslavia), has been in compliance with the program of testing the Sava river water and sludge quality along the river flow. The establishing of sludge pollution range is not based upon values of maximum allowable concentrations. The most complex is the issue of heavy metals contents, since these also represent the natural contents of soil and minerals. However, considering the process of migration and distribution of heavy metals, and other harmful and dangerous matters discharged from utilities, industrial and power supply facilities, provides the basis for estimating the environmental pollution as well.

2001
Zivic, I. (Bioloski fakultet, Beograd (Yugoslavia). Institut za zoologiju) | Markovic, Z. | Brajkovic, M.
The investigations of the macrozoobenthos of the Crvena Reka river (Serbia, Yugoslavia), left tributary to the Nisava river, were performed during July in 1999. Samples were collected from 15 localities, from the spring of the Crvena Reka river (originating from Toponicka and Vetska rivers) to the lower course, the aim being to investigate the diversity of macrozoobenthos of these running waters which had not been investigated. The community of macroinvertebrates of the Crvena Reka river and the streams, which make it, consists of 54 determined taxa (at species and genus level) from 16 animal groups. Larvae of Ephemeroptera and Trichoptera have the greatest diversity, each having ten determined taxa. The middle course of the Topnicka river (locality T4) is characterized by the greatest diversity (25 taxa), while the springs (due to constant ecological parameters) have poor diversity with two and one determined taxa in locality V1 and V2, respectively. The water quality of the investigated river and streams, which make it, on the basis of the results of saprobiological analysis, is of beta-mezosaprobic quality, i.e. second class of quality in most localities.
