water

History of an environmental medium, history of social uses of water; water as a central resource for societies, often in combination with "pollution" or as such, physically as surface waters (cp. "aquatic ecosystems") or ground water.

The author in this article introduces interesting fact of providing drinkable wather in Slovenia from underground even if this county has lots of rivers. He stresses the reasons of providing it from underground world. He exposes the advantages and disadvantages of such actions.

Author describes Pseudomoraria triglavensis gen. n., sp. n. (Copepoda, Harpacticoida) as animal found in the highest areas of the Slovenian Alps in the centre of Triglav national park. The article discusses differences in relation to Moraria,Morariopsis and Paramorariopsis and also points out its adjustment to this special enviroment, describes its ecology.

The REFREsh Danube project aims to reduce the landfilled amount of municipal solid waste, which is a source of water and soil pollution, by its use as refuse-derived fuel in the cement industry of Novi Sad (Serbia). The main actors involved are Lafarge Beočin Cement Factory, Municipality of Novi Sad, JPK Čistoća (waste-management company) and experts from interdisciplinary fields.

This project addresses the need to assess the environmental and health risks of chemicals used in food production, since their release into the environment may lead to different ecological effects. The occurrence and effects of selected chemicals on wildlife and humans will be addressed to provide data sets, which are necessary for scientifically-based risk assessment. Special emphasis will be put on the combined effects of environmentally relevant mixtures. A combination of state-of-the-art methods will be applied to predict synergistic and/or additive effects of combined exposure.

This article presents the analytical results from water samples from Danube River for the period  23.05.2011 - 31.05.2011. The results reveal presence  of sediments, insoluble substances and oil products.The test exponent values of the water samples from the river Danube are in the admissible norms, according to the current Regulatory base. Despite this, these exponents have to be minimized to achieve the higher water quality.

Danube as a very large European river  contributes seriously to the economic development of Europe. The geographical location of the river  is an important condition for the impact of different factors to the water quality. The water pollution of Danube river on Serbian territory is the major goal of this study.

Ditches, old river beds and small ponds comprise important biotopes for fish fauna, providing spawning grounds, as well as habitat and food sources for juvenile fish. These areas are very vulnerable to pressures such as river regulations or the construction of hydroelectric power plants. The article analyses human-induced changes in fish fauna based on the example of the Steyregger Graben, an oxbow lake [alluvial trench] of the Danube in Linz (Upper Austria).

The Black Sea is the world’s most isolated sea. As its catchment area is six times larger than its surface area, and every year about 350 km³ of river water from an area covering almost a third of continental Europe flow into the Black Sea, the Sea is very vulnerable to pressures resulting from land-based human activities such as industry, agriculture and growing urban communities. These activities are potential sources of pollution, and if not properly managed can have a negative impact on the water quality and water uses.
