The water hyacinth Eichhornia crassipes originates from Brazil, and although it represents one of the most troublesome and invasive of water weeds, it is also one of the best phytoremediants of polluted water. The biomass becomes saturated with pollutants, which can then be removed from the water by harvest of the biomass and its composting, a process which achieves a substantial reduction in the mass requiring further processing (e.g., incineration under controlled conditions). The species is highly susceptible to frost, but in frost-free environments, its introduction is risky as it can readily become uncontrollable.

To determine the effects of the deprivation of specific micronutrients on the water hyacinth (Eichhornia crassipes), Colley et al. (1979) studied the rate of uptake of iron and manganese in comparison with phosphorus. Results indicated that all three elements were actively absorbed by the root systems, but the rates of absorption differed markedly. The rate of absorption of manganese by roots was 13 and 21 times that for radio-iron and -phosphorus, and iron was taken up by the roots at nearly twice the rate of phosphorus. Manganese translocation appeared to be faster than phosphorus translocation by an order of magnitude and 65 times faster than iron translocation.

Aquatic species were also found to be hyperaccumulators in wetland ecosystems (Williams, 2002). Ceratophyllum demersum is described as an arsenic accumulator (Kalbitz and Wenrich, 1998), whereas water hyacinths, Eichhornia crassipes, have been found to be effective in accumulating cadmium, lead, and mercury, and in the uptake of pesticides residues. Duckweed Lemna minor) and water velvet (Azolla pinnata) were both found to effectively remove iron and copper at low concentrations in laboratory experiments, and also cadmium. The yellow water lily (Nuphar variegatum) accumulated copper and zinc.

Waterhyacinth plants [Eichhornia crassipes (Mart.) Solms], which infest waterways in many parts of the world, were used as a model system for studying uptake of metal ions by floating acpiatic plants. Observed rates of uptake of manganese(II)-54 and iron(III)-59 by water hyacinth compare favorably with the values expected based upon a coordination model control by chelation with dihydrogen ethylenediamine- tetraacetate ion and control by metal(II) carbonate solubility. Agreement depends upon the assumption of the reduction of iron(III) species by the plant.
