Název v původním jazyce

Bioavailability of arsenic, cadmium, iron and zinc in leafy vegetables amended with urban particulate matter suspension

Popis výsledku v původním jazyce

The bioavailable portions of arsenic (As), cadmium (Cd), iron (Fe), and zinc (Zn) in leafy vegetables amended by urban particulate matter (PM) via soil and/or foliar application were investigated in a model pot experiment, in which lettuce and chard werecultivated. By using the Physiologically Based Extraction Test (PBET) simulating in vitro human digestive processes in the stomach and small intestine, the bioavailable portions of toxic elements from PM amended plant biomass were extracted. Extractableportions of elements by a simulated gastric solution from biomass decreased for lettuce in the order Zn > Cd > As > Fe, in the case of chard in the order As > Zn > Cd > Fe. No significant effects of PM physical fractions or soil were observed. Althoughthe bioavailable element portions in the PM samples were lower compared to plants, the bioavailable element contents in foliar PM amended plant leaves exceeded the control and soil PM amendment levels, even after biomass washing.
