Opis:: Rivers are considered as one of the main resources of water supply for various applications such as agricultural, drinking and industrial purposes. Also, these resources are used as a place for discharge of sewages, industrial wastewater and agricultural drainage. Regarding the fact that each river has a certain capacity for acceptance of pollutants, nowadays qualitative and environmental investigations of these resources are proposed. In this study, qualitative investigation of the Talar river was done according to Oregon Water Quality Index (OWQI), National Sanitation Foundation Water Quality Index (NSFWQI) and Wilcox indicators during 2011–2012 years at upstream, midstream and downstream of the river in two periods of wet and dry seasons. According to the results of OWQI, all of the values at 3 stations and both periods are placed at very bad quality category and the water is not acceptable for drinking purposes. According to NSFWQI, the best condition was related to the upstream station at wet season period (58, medium quality) and the worst condition was related to the downstream in wet season period (46, very bad quality). Also the results of Wilcox showed that in both periods of wet season and dry season, the water quality is getting better from upstream station to the downstream station, and according to the index classification, the downstream water quality has shown good quality and it is suitable for agriculture.

Opis:: In the study suitability of water quality index approach and environmetric methods in fi ngerprinting heavy metal pollution as well as comparison of spatial variability of multiple contaminants in surface water were assessed in the case of The Gediz River Basin, Turkey. Water quality variables were categorized into two classes using factor and cluster analysis. Furthermore, soil contamination index was adapted to water pollution index and used to fi nd out the relative relationship between the reference standards and the current situation of heavy metal contamination in water. Results revealed that surface water heavy metal content was mainly governed by metal processing, textile and tannery industries in the region. On the other hand, metal processing industry discharges mainly degraded quality of water in Kemalpasa and Menemen. Furthermore, Kemalpasa region has been heavily affected from tannery and textile industries effl uents. Moreover, pollution parameters have not been infl uenced by changes in physical factors (discharge and temperature). This study indicated the effectiveness of water quality index approach and statistical tools in fi ngerprinting of pollution and comparative assessment of water quality. Both methods can assist decision makers to determine priorities in management practices.

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

Opis:: 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, Ni, Zn, Cd), sulphates and coliform germs. The average WPI values were calculated for the observed periods based on the comparison of the annual average values of the listed parameters and defined standard values for the I water quality class (according to the Regulation on the Hygienic Acceptability of Potable Water of the Republic of Serbia). The highest pollution degree was recorded in the Borska Reka River, where heavy metal levels (especially manganese and iron) were significantly increased. These metals are indicators of inorganic pollution (primarily caused by copper mining). Also, increased values of the organic pollution indicators (ammonium, coliform germs, Five-Day Biological Oxygen Demand - BOD5) in the Borska Reka and the Timok rivers are the result of uncontrolled domestic wastewater discharge.

Tytuł:: The use of Allium cepa L. assay as bioindicator for the investigation of genotoxic effects of industrial waste water

Tematy:: Allium cepa assay

Opis:: In this study, genotoxic potential of industrial waste water (IWW) samples was investigated using Allium cepa assay. The root tips were treated with different IWW samples (A, B and C) for 48 hours. The effects of IWW on cytological effects were determined. It was found that all IWW samples significantly increased the percentage of total abnormality. Mitotic chromosomal abnormalities such as irregular metaphase, stickiness, c-mitosis, micronucleus, vagrant chromosomes and bridges were determined. Furthermore, a significant reduction for the mitotic index that is indicative of cellular toxicity was observed in root tips cells, which were treated with IWW samples. A. cepa assay can be used as useful tool for the detection of genotoxic and cytotoxic potential of IWWs.

Opis:: Labile fractions of organic matter can rapidly respond to changes in soil and they have been suggested as sensitive indicators of soil organic matter. Two labile fractions of organic carbon in the soils amended with fresh municipal sewage sludge in two rates (equivalent of 60 kg P ha-1 and 120 kg P ha-1) were studied. Soils under studies were overgrown with Salix in Germany, Estonia and Poland. In Polish soils application of sewage sludge increased the content of both labile organic carbon fractions (KMnO4-C and HWC) for a period of one year. Estonian soils were stable and no distinct changes in labile organic carbon fractions occurred.
Labilne frakcje materii organicznej mogą być wyrazem zmian zachodzących w glebie i stanowią one wskaźniki jakości materii organicznej. Badano dwie frakcje labilnego węgla organicznego w glebach nawożonych osadem ściekowym w dwóch dawkach (będące równoważnikiem 60 kg P ha-1 i 120 kg P ha-1). Badane gleby były porośnięte gatunkami wierzby krzewiastej w Niemczech, Estonii i Polsce. W badanych glebach w Polsce zastosowanie osadów ściekowych spowodowało wzrost obu analizowanych frakcji węgla (KMnO4-C i HWC). Natomiast gleby estońskie były stabilne i nie stwierdzono zmian w labilnych frakcjach węgla organicznego.
