summary The iron plaque on roots of Aster tripolium L. growing in waterlogged salt marsh soil adsorbed appreciable amounts Zn and Cu, with maximum Zn/Fe Cu/Fe ratios 0.1 When concentrations or Cu the are expressed as mg metal kg −1 FeOOH (assuming that consists mainly FeOOH), was up to 680 2000 times higher than surrounding sediment, respectively. concentration red (with plaque) white (without plaque). field sampled were correlated amount soil, whereas only significantly soil. In vitro...
Bioavailability of engineered metal nanoparticles affects uptake in plants, impacts on ecosystems, and phytoremediation. We studied translocation Ti plants when the main source this was TiO2 nanoparticles. Two crops (Phaseolus vulgaris (bean) Triticum aestivum (wheat)), a wetland species (Rumex crispus, curly dock), floating aquatic plant (Elodea canadensis, Canadian waterweed), were grown nutrient solutions with (0, 6, 18 mmol L(-1) for P. vulgaris, T. aestivum, R. crispus; 0 12 E....
Arsenic present in salt marsh soil is taken up by plants and subsequently transferred to other parts of the ecosystem. The reduced state bulk marshes favours mobility arsenic. In rhizosphere however, arsenic may be immobilized owing oxidation (III) less mobile (V) adsorption iron (hydr-)oxides. a field survey concentrations vicinity roots Aster tripolium were higher than soil. greenhouse experiment accumulation occurred, which could due oxidizing activity plant (or) microorganisms. This...
Abstract Earlier work from our laboratory on Indian mustard (Brassica juncea L.) identified the following rate-limiting steps for assimilation and volatilization of selenate to dimethyl selenide (DMSe): (a) uptake selenate, (b) activation by ATP sulfurylase, conversion selenomethionine (SeMet) DMSe. The present study showed that shoots selenate-treated plants accumulated very low concentrations dimethylselenoniopropionate (DMSeP). Selenonium compounds such as DMSeP are most likely precursors...
