Distribution of arsenic compounds in Plantaginaceae and Cyperaceae plants growing in contaminated soil

Popis výsledku v původním jazyce

The ability of plant species to accumulate arsenic (As) species in the biomass from soils is variable. In this study, the ability of Plantago lanceolata (Plantaginaceae) and three wetland plant species of the family Cyperaceae naturally occurring in the soils with an elevated As in the Czech Republic were investigated. The plants were cultivated in an As-contaminated soil reaching 735 mg kg-1 of the total As. The total As in plants reached up to 8.3 mg kg-1 in leaves, and up to 155 mg kg-1 in roots of Carex praecox. Dominant As compounds were arsenite and arsenate with a small abundance of dimethylarsinic acid (DMA). In Cyperaceae, small percentages of arsenobetaine (AB) and arsenocholine (AC) were detected, suggesting the ability of these plants to transform As into less toxic compounds. Moreover, the role of As(V) sequestration on iron plaque on the root surface of Cyperaceae was confirmed. Root washing with oxalic acid partially disrupted the iron plaque for the better release of arsenate.
