Bioaccumulation of arsenic from water and sediment by a

Arsenic bioaccumulation in the deposit-feeding polychaete Arenicola marina has been investigated using biodynamic modelling. Radiotracer techniques were used to determine the rates of uptake of As as arsenate from water and sediment and its subsequent efflux in the laboratory. Lugworms accumulated As from solution linearly at concentrations of

Uptake of arsenic by New Zealand watercress (Lepidium

01/01/2003 Liddle (1982) conducted experiments involving the uptake of arsenic by Ceratophyllum demersum. He found that plants grown in arsenic solutions with <0.1 mg l −1 arsenic (III or V) reached equilibrium in 1 or 2 days, while plants in >0 5 mg l −1 of this element, needed up to a week to reach equilibrium. Arsenic concentration in plants increased with increasing concentration of arsenic in

Enhanced uptake of As, Zn, and Cu by Vetiveria zizanioides

A greenhouse study was conducted to investigate the feasibility of using vetiver and maize for remediation of arsenic (As)-, zinc (Zn-), and copper (Cu)-amended soils and evaluate the effects of chelating agents on metal uptake by these plants. Vetiver had a better growth (dry weight yield of root and shoot) than maize under different treatment conditions. The effects of different chelating

Impact of eutrophication on arsenic cycling in freshwaters

The reduction and methylation of arsenic were enhanced at the sediment-water interface, owing to the significant increase in arsenate reductase genes (arrA and arsC), and arsenite methyltransferase genes (arsM) caused by increased anoxia. The analysis of synchrotron-based X-ray absorption spectroscopy indicated that the concomitantly released natural organic matter (NOM) and sulfur (S) at the
