Some indicators of water quality of the Tamis river

Abstract

This paper shows the results obtained in field analysis performed at the Tamiš River, starting from the settlement Jaša Tomić (the border between Serbia and Romania) to Pančevo (the confluence of Tamiš into the Danube). The Tamiš is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pančevo. Over the years, the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamiš River at every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamiš is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamiš River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further decrease the pollution of the river's water.

Analysis of Basic Physical-Chemical Parameters, Nutrients and Heavy Metals Content in Surface Water of Small Catchment Area of Karašica and Vučica Rivers in Croatia

“…Considering the 50th percentile of total nitrogen content, the quality of the Karašica River surface water at sampling site 21012 can be described as good Gvozdić et al (2012) reported that the median concentration of nitrates in the River Drava surface water is relatively low compared to other rivers in western Europe (4.4-3.8 mg N/L) [27]. These values are similar to those obtained in the rivers in eastern Europe, for instance in the Danube and the Sava River (2.1-2.0, 1.6-0.95 and 1.3-1.2 mg N/L, respectively) [36,37].…”

Multi-criteria ranking of the Danube water quality on its course through Serbia

“…These parameters show physical, chemical and microbiological characteristics of the water and they are used in WQI (Water Quality Index) methodology (Scottish Development Department, 1976) in determining the overall water quality of the surface water. Based on the use of standard parameters for water characterization, the WQI sets the criteria for classification of surface water quality (Babović et al, 2011;Reza, & Singh, 2010;Banerjee & Srivastava, 2009;Sanchez et al, 2007;Kannel et al, 2007).…”

Provenance and Pollution Status of River Sediments in the Danube Watershed in Serbia

“…On several shorter sections of the course, Tamiš meanders laterally, eroding higher relief, loess plain, and loess terrace, forming high riverbanks in the form of steep sections and slopes. Tamiš River is polluted by water supply facilities, fish ponds, industry, agriculture, and urban settlements [26]. Forty-seven samples were collected from the Tamiš River for this study.…”
