The purpose of this paper is to determine the effectiveness of a reed bed sludge treatment system in Italy after 1 year of operation in two urban wastewater treatment plants, where Phragmites australis was planted directly in emergency beds rearranged for the project. To evaluate the process of stab

In this study, the performance of a combined subsurface vertical and horizontal flow constructed wetlands system, designed for rural domestic wastewaters treatment and with theoretical hydraulic retention time of 2 d and 3.6 d, respectively, was investigated. Several water quality parameters includi

Eutrophication caused by excess nutrient loads is the main problem for Estonian surface waters. The assessment of the type of human activity on the catchment area that may cause an impact on the status of a water body is needed for successful implementation of the Water Framework Directive. The lack

The comparison of eutrophication development in two Brazilian water supply reservoirs has shown the convenience of adopting different management strategies according to climatic conditions and to the balance between nutrient concentrations. These techniques should be directed to the prevention of cy

The Korissia lagoon is located in the southwest of Corfu Island, Greece. It is a shallow coastal ecosystem of great aesthetic and ecological importance, included in the Natura 2000 network of protected areas. The lagoon is connected to the sea by an artificial channel and its depth varies between 0.

The Axios/Vardar River, an interboundary river located in the Balkan Peninsula, drains the region of southern Serbia, almost 80% of the Former Yugoslav Republic of Macedonia territory and some parts of northern Greece. This study is based upon long-term data (1979–2003) of nitrate, nitrite, ammonium

The Potpec reservoir is situated in the southwest of Serbia. It has been formed in 1977 on the Lim river and used for the electric energy production. In this paper, the results of the qualitative and quantitative analysis of zooplankton, as well as saprobiological analysis of plankton community, are

The aim of this study is to present the seasonal variation of nutrients in the water column and the bottom sediments of Vistonis Lagoon, a hypereutrophic Mediterranean coastal lagoon located in Northern Greece, and to estimate the impact of bottom sediments on the water quality of this lagoon. Nutri

The aim of this study was the qualitative and quantitative assessment of impacts on the physicochemical characteristics of the water column and the sediment caused by an intensive marine fish farm. The study area was the Plateia Island which is located in an open seawater area in the outer part of A
