Phytofiltration of arsenic by aquatic moss (Warnstorfia

Arsenic removal from 0, 1, or 10% Hoagland nutrient solution containing 0–100 μM arsenate was followed over 192 h, and the total As in aquatic moss after treatment was analysed. The uptake and speciation of As in moss cultivated in water containing 10 μM arsenate or arsenite were examined as As uptake in living (absorption + adsorption) and dead (adsorption) plant parts.

Accumulation of arsenic by aquatic plants ScienceDirect

Ten varieties of aquatic plants were collected from 22 pools resulting from tin-mining activities in and around Kuala Lumpur. The concentrations of arsenic in these plants partially reflected the concentrations of arsenic in pool water, which ranged from 0.002 to 0.25 μg ml −1.Uptake of arsenic by one of the aquatic plants, hydrilla, Hydrilla verticillata Casp., was studied in the laboratory.
