Organic salts enhanced soil risk elements leaching and bioaccumulation in Pistia stratiotes

Popis výsledku v původním jazyce

The objective of the present study was to investigate the efficiency of organic acid salts to enhance mobility of Cd, Pb, and Zn in soil with subsequent bioaccumulation in water plant (P. stratiotes). Column flushing and pot rhizofiltration experiment were conducted. Statistical analyses ANOVA with Tukey?s HSD test were used for results analysis. Results revealed statistically different efficiency of four tested organic acid salts (P < 0.05). Ammonium citrate was the most effective for release of all three risk elements. Cd, Pb, and Zn were mobilised by 45%, 321%, and 116% more than under 0.11 mol/L acetic acid (exchangeable form), respectively. Ammonium oxalate and acetate proved lower efficiency (P < 0.05). Young plants showed higher bioconcentrationfactor (BCF) than old ones in leaves as well in roots. Old plants proved lower residual metal concentration in solution. Mobilisation efficiency and metals accumulation in biomass were the highest under citrate and tartrate treatments.
