Recently, various researches have focused on the environmental condition assessment of oxbow lakes along rivers. In this study we investigated the bed morphology, conductivity and the changes of macro-and microelements in the oxbow, named Kacsa-tó, that was formed by the 45 th cutoff on Tisza River, then the results were plotted using GIS softwares...

We aimed to reveal the risk of arsenic in a Hungarian river (the Tisza) at the mouth of a polluted canal. Four sampling sites were involved in this work and samples were collected on a weekly basis for arsenic and sodium, and on a monthly basis for nutrients. Significant differences were found concerning each studied component between the sampling...

Az antropogén szennyeződésekkel szemben a felszín alatti vizek esetenként magas arzénkoncentrációja a természetes geokémiai folyamatok eredménye. Az arzén ma a legnagyobb természetes kontamináció a felszín alatti vizekben, és ennek csökkentése a XXI. század nagy vízgazdálkodási kihívásai közé tartozik. A Lónyay-főcsatorna vízgyűjtő területén a föld...

Research on spatial and temporal changes of hydrological elements of the environment is an important issue of most emerging tasks due to the possible trends of the climate change. In this study we investigated a catchment (Canal Lónyay-főcsatorna) whichwas situated on the northeastern part of Hungary, in the Nyírségmezoregion. We examined some char...

Since it is Hungary's second largest river, the River Tisza is important both as a river and because of its active floodplain. The contaminations endanger the aquatic and the related living nature as well as the farming in the active floodplain. The water quality of the river is examined regularly by the competent authority but far less information...
