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.
