TL;DR: The immobilization of the metals during pH increase and the subsequent remobilization caused by re-acidification can be well described by a geochemical equilibrium speciation model that accounts for metal complexation at hydrous ferric oxides, for ion exchange on the zeolite surfaces, as well as for dissolution and precipitation processes.

TL;DR: Investigation of the influence of the biodegradable chelating agent SS-EDDS on uptake of essential and non-essential metals by sunflowers from nutrient solution shows that syntheticChelating agents do not necessarily increase uptake of heavy metals, when soluble concentrations are equal in the presence and absence of chelates.

TL;DR: In this paper, a pot experiment was conducted to investigate the relationship between soluble concentrations of arsenic (As) in soil and its accumulation by maize (Zea mays), English ryegrass (Lolium perenne), rape (Brassica napus) and sunflower (Helianthus annuus) on two different soils: a calcareous Regosol (silty loam) and a non-calcareous R loam (sandy loam).

TL;DR: In this article, the effect of phytoremediation on metal fluxes has been investigated and validated using validated mechanistic models, such as root-metal interactions in these typically heterogeneous media.
