Heavy Metal Solubility and Uptake We have under taken a considerable amount of work on the bioavailability, transfer of metals in soils and their uptake by plants. A feature of the work has been the use of isotopic methods to descriminate between metals of different labilities within soil (i.e. those readily able to exchange with soil solution and those fixed in some way). Much of the modelling work has focussed on using this information to develop readily applicable models of metal solubility and plant uptake. i.e. models which can be applied with the minimum of soil and plant specific information. More recently this work has applied similar methods to the field scale testing of phyto-remediation of arable soils contaminated with metals (i.e. using plants to extract metals from soils). More informaiton on these topics can be found under the links opposite.
