The adsorption capacity of an ocher decreases arsenic intake in maize; Adsorpcna kapacita okru znizuje prijem arzenu pri kukurici

Abstract

The aim of the experiment was to compare the growth of maize (Zea mays L.), hybrid Valentine, in two types of contaminated soil substrate (ocher and stacks) with different concentrations of arsenic (As) derived from an old mining site in Pernek in the Small Carpathians. Plants were grown in a greenhouse for 15 weeks. We found that although the total concentration of As in stacks was 2.6 times lower than in ocher (90.05 mg kg{sup -1} in stacks and 236.8 mg kg{sup -1} in ocher) the plants grown in stacks accumulated in their tissues more As compared to the plants growing in ocher. Moreover, plants in stacks were significantly smaller, they produced less biomass and bloomed later. This paradox can be explained by reduced mobility of As in ocher substrates characteristic by high content of hydro-oxides of Fe. These compounds are in fact capable of binding arsenates, what leads to decrease of their concentration in the soil solution, and thus the availability for the plants. (authors)
