Cím:	Examination of zinc and iron mobilization with acid treatments and the metal content of maize and stinging nettle in the active floodplain of the River Tisza / Gyöngyi Gosztonyi, Mihály Braun, József Prokisch, Szilárd Szabó
Dátum:	2011
Megjegyzések:	n this paper the mobilization of zinc and iron was studied in soil samples from the Boroszló-kert Dead-Tisza region. Besides the determination of the soil characterizations, the effects of different acid treatments on the metal mobilization were examined with nitric acid in five concentrations and with three extraction times. HNO3+H2O2 digestion and NH4-acetate + EDTA extraction were also carried out. Moreover, the metal uptake of two plant species (Zea mays from ploughlands, and Urtica dioica L. from orchards) was also studied. The decrease of pH caused significant metal mobilization, and the change of the pH is closely related to the soil properties, especially to the granulometric composition. Fe was less mobilizable than Zn. More metal was mobilized from the samples derived from ploughlands, and maize accumulated more Zn and Fe. However, the samples of ploughlands contained more CaCO3 than the samples from orchards.

Cím:	Process of overturning due to a floodwave in an oxbow lake of Tisza River / Gábor Türk, László Bertalan, Boglárka Balázs, Edina Fehérné Baranyai, Szilárd Szabó
Dátum:	2016
ISSN:	1842-4090 1844-489X
Megjegyzések:	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 45th cutoff on Tisza River, then the results were plotted using GIS softwares. Our aim was to examine the specific electric conductivity and its spatial pattern at the end of the spring flood at 2013. We analyzed water samples collected by a stratified sampling system so as to conclude the extent of overturning. The inflow from the flood resulted lower conductivity values at the extensive SE part than at the distant NW part. Initially the fresh water supply from the flood does not reach the distant parts; thus, the overturning takes place more slowly so the water body replacement of the oxbow occurs constantly. Our results show that at the beginning of the flood the oxbow could be divided into two distinct heterogeneous parts. Based on the conductivity values at time of the measurement, we found that the overturning is not yet complete.
