What is Metal Speciation? Definition of Metal Speciation: A metal can exist as different chemical forms/species [e.g. As(III) and As(V) species of arsenic (As)] . (). Factors influencing metal bioavailability in soils: preliminary investigations for the development of a critical loads approach for metals. Chemical Speciation & Bioavailability: Vol. 10, Cited by:
The toxicity, bioavailability and mobility of certain elements are to a large extent determined by the form in which it is present. Consequently, a metal speciation analysis can provide valuable extra information compared to traditional total concentrations. Over the last few years, new legislation and guidelines have also started introducing. Metal Speciation and Its Role in Bioaccessibility and Bioavailability Richard J. Reeder; Richard J.

Project Methods The project will investigate the effect of soil chemical processes on chemical speciation and bioavailability of heavy metal comtaminants in soil in two focus areas. In the first focus area, the effect fo chemical speciation and bioavailability on ecological receptors used for development of soil screening levels will be studied as follows. etc, metal-biocompounds which could, in principle, contain the metal. In these instances, speciation of a trace element in living organisms calls for a knowledge and judicious choice of different-principle based separations assisted by different -complementing-each-other specific detectors (7).

The effect of chemical speciation on metal uptake or bioavailability can be accounted for by expressing the uptake rate constants on a free ion activity scale (Campbell ). Competitive and noncompetitive effects can be considered by defining a maximum rate of transport and a metal binding constant to characterize the metal transporters Cited by: 5.
