Estimation of water quality of Sava River (Vojvodina, Serbia) in the period 2004-2011 using Serbian Water Quality Index (SWQI) (original) (raw)

Assessment of water quality of the Tisa River (Vojvodina, North Serbia) for ten year period using Serbian water quality index (SWQI)

Geographica Pannonica, 2014

The WQI method is most frequently used in expert and scientific research and basically it provides a mechanism for cumulative representation, numeric expression and defining a certain level of water quality. This paper aims to assess water quality of the Tisa River in Vojvodina (North Serbia) for the 2003-2012 period. Serbian Water Quality Index (SWQI) was used for assessment of the river water quality. WQI is expressed as a single value ranging from 0 to 100 (best quality) derived from numerous physical, chemical, biological and microbiological parameters. The results of SWQI for the Tisa River were mainly rated as good. Also, in this study it is noticed a clear decrease in water quality during warmer period of the year. Also, this study shows that water quality along the Tisa River decreases slightly but steadily downstream, from Martonoš to Titel station and all along the length of the river provides values that according to SWQI descriptive quality indicator has been defined as good (72-83). The main problem of SWQI used in this paper is that it does not involve parameters of heavy metals concentration.

Statistical Analysis of Water Quality Parametres of Drina River (West Serbia) in the Period 2004-2011

Polish Journal of Environmental Studies, 2015

Rational and preservation utilization of water resources represents one of the main problems of the 21 st century. Water as a resource is a valued quantity, quality, and by location, where the quality is a condition of the water system, expressed through physical-chemical, chemical, and biological indicators. The important aspects taken into consideration when examining the top-priority problems of water quality are economic influence, the influence on human health, influence on the ecosystem, and influence of the geographic area, as well as duration of the influence [1]. Changes in the physico-chemical characteristics of water quality are influenced not only by anthropogenic factors, but also by combined interactive natural processes such as hydrological conditions, topography and lithology, climate, precipitation inputs, catchment area, tectonic and edaphic factors, erosion, weathering of crustal materials and bedrock geology, in combination with environmental influence [2]. It should be also taken into account that the Republic of Serbia is striving toward membership within the EU, and reaching good water quality represents an important challenge [3]. The most important legal framework within the European Union (EU), which regulates water policies, is the Water Framework Directive (WFD) [4]. River systems play an important role in the sustainable development of the whole environment, especially when

The Assessment of the Danube Water Quality in Serbia

2012

This paper considers the assessment of the Danube water quality in accordance with the current law regulations in Serbia by applying the Serbian Water Quality Index (SWQI) method and Directive 75/440/EEC. Monitoring of the surface water quality is performed by the Republic Hydrometeorological Service of Serbia (RHSS) so data found in the period from 2005 to 2009 are used. Comparative analysis shows the incompatibility of classification parameters of the Danube water quality. Also, the knowledge of these regulations provides a better and more reliable monitoring of the surface water quality. The paper aims to show the preparations of Serbia for the European Union (EU) integration processes along with the challenges and difficulties in the process of implementation of EU Water Framework Directive (WFD).

Assessing Surface Water Quality in the Serbian Part of the Tisa River Basin

Polish Journal of Environmental Studies, 2019

The aim of this study was to evaluate the quality of the Tisa River on its flow through Serbia. The water quality status and the spatial and temporal trends along the Tisa River were assessed through the application of ten SWQI parameters derived from a six-year public database of environmental data (2011-16). Also, the created data set was treated by multivariate techniques in order to identify the similiraties and differences between sampling periods and locations, recognize variables that affect the temporal and spatial water quality and present anthropogenic impact on water quality parameters. This study reveals that water quality along the Tisa River decreases slightly downstream. Obtained values of SWQI descriptive quality indicator indicated that water quality on this course, during the monitoring period, was good (72-83) and very good (84-89). Multivariate statistical techniques (PCA/FA) led to the conclusion that the changes in water quality mostly occur under the influence of organic pollutants (anthropogenic) and nutrients (total phosphorus, ammonia, etc.).

The Assessment of the Surface Water Quality Using the Water Pollution Index: A Case Study of the Timok River (The Danube River Basin), Serbia

Archives of Environmental Protection, 2012

The Assessment of the Surface Water Quality Using the Water Pollution Index: A Case Study of the Timok River (The Danube River Basin), Serbia The Timok River (202 km long, 4547 km2 basin area) is located in East Serbia. It is a right tributary of the Danube River and one of the most polluted watercourses in Serbia. On the basis of the data provided by the Republic Hydrometeorological Service of Serbia, the paper presents an analysis of water quality and pollution using the combined physico-chemical WPI index (Water Pollution Index) calculated for two periods - 1993-96 and 2006-2009 at four hydrological stations: Zaječar-Gamzigrad (Crni Timok River), Zaječar (Beli Timok River), Rgotina (Borska Reka River) and Čokonjar (Timok River). The following parameters were taken into consideration: dissolved O2, O2 saturation, pH, suspended sediments, Five Day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (CODMn), nitrites, nitrates, orthophosphates, ammonium, metals (Cu, Fe, Mn, Hg,...

Water quality assessment of the Montenegrin part of the Lim river using the Serbian water quality index (SWQI)

Zbornik radova - Geografski fakultet Univerziteta u Beogradu, 2021

The paper analyzes the water quality of the Montenegrin part of the Lim River using the Serbian Water Quality Index (SWQI) method. This method uses ten physical, chemical, and microbiological parameters (temperature, pH value, electrical conductivity, oxygen saturation, BOD5 , suspended solids, total nitrogen oxides, orthophosphates, ammonium, coliform bacteria) and summarizes them in a water quality index number. Data from the Institute of Hydrometeorology and Seismology of Montenegro (IHMS) from the Annual Reports on Water Quality from 2010 to 2018 were used to assess water quality. The results of this research, according to SWQI, show that in the upper course of the Montenegrin part of the Lim, at the control stations Plav and Andrijevica, water has excellent quality. Downstream, passing through the urban areas of Berane and Bijelo Polje at the control stations Skakavac, Zaton, Bijelo Polje, Dobrakovo, the water quality enters the class of very good and good quality. The results ...

Application of the Water Pollution Index in the Assessment of the Ecological Status of Rivers: a Case Study of the Sava River, Serbia

2016

Water quality and status assessment of water bodies could be based on a large number of various parameters, including physical, chemical, hydromorphological, microbiological and biological. Often it is difficult to interpret the results of water status assessment when numerous quality elements are analysed, since each may indicate different quality class. The Water Pollution Index (WPI) overcomes this problem by providing a single assessment score. Previously, WPI was calculated using physical and chemical parameters combined with microbiological parameters. Biological quality elements are recommended by the EU Water Framework Directive (WFD) as obligatory for the assessment of ecological status of water bodies. For the first time in this study, the index was modified to include also biological parameters. Sampling and field measurements were done in 2007–2011, at three sites on the Sava River in the Belgrade region. According to the obtained WPI values, the river was assessed as po...

Determination of chemical quality parameters in surface water samples from rivers Sava, Danube, and Topciderka

Medicinski podmladak, 2016

Water quality is defined by numerous physical, chemical and biological parameters,the content of organic and inorganic substances, and its monitoring has become a global health, economic and legal interest in recent decades. In this paper, some of the most important indicators of chemical surface water quality were determined in samples from the river Sava (Ada i Ušće), Danube (Pristanište i Kej) and Topčiderka (Rakovica). Water samples from selected locations were collected in November 2014 and chemical parameters were determined using standard analytical procedures. The results were obtained in the following range: pH (5.71-6.40), content of dissolved oxygen (11.04-11.99 mg/dm 3), chloride (20.89-32.82 mg/dm 3), alkalinity (207.9-300.9 mg CaCO 3 /dm 3), acidity (31.79-54.90 mg CaCO 3 /dm 3), calcium (37.23-54.90 mg/dm 3), magnesium (6.90-23.65 mg/dm 3), total water hardness (137.6-235.8 mg CaCO 3 /dm 3), chemical oxygen demand-COD (4.08-9.12 mg O 2 /dm 3). Tested parameters indicate no significant pollution of the surface water, but in order to perform the correct categorization of water in these rivers, it would be necessary to do further testing of physical, chemical and biological indicators of the water quality.
