Abstract: The basic aim of the present study is the water quality assessment of the Igrice marsh (Nature Conservation Area, situated in boundary of town of Nyíregyháza, northeastern part of Hungary) using by bioindication and chemical analysis. The phenomenon of biofiltration is well known: the different wetlands are efficient at removing nutrients and pollutants from through-flowing water by means of their plant communities (mainly reedy, tussocky and large sedge areas). Considering the thought mentioned above, the basic questions of this study were the followings: how does the quality of water flowing through the marsh change and how is it manifested in the presence or even absence of the different macroinvertebrate taxa and in the chemical parameters? The water quality assessment was made by using the Belgian Biotic Index (BBI), an index based on the presence or absence of aquatic macroinvertebrate taxa and by chemical parameters (conductivity, pH, NO2-,NO3-, NH4+, Cl-, Fe2++Fe3+, orthophosphate). In accordance with the expectations, the results indicated that stream water, flowing through the marsh has been improved in quality by biofiltration processes of the wetland ecosystem.
It could be seen based on the presence of the taxa indicating better water quality and the positive changes in the chemical features at the outflow part of the canal. As a conclusion, it could be established that the Igrice-marsh is able to improve the quality of the through-flowing water effectively. Nevertheless, using this wetland for such a function is not possible, because the habitat of the marsh is protected and there is no information about the effective buffer capacity of the area.
