It is increasingly realised that the distribution, mobility and biological availability of chemical elements depend not simply on their concentrations but, critically, on the forms in which they occur in natural systems. Continuing developments in analytical chemistry have made speciation practicable even where analytes are present at trace levels (as is often the case in natural samples). In the second edition of this book, the expertise of scientists involved in chemical speciation in various fields have been brought together to provide an overview of the current status of speciation science and indicate how the field may develop in the future 606 $aSpeciation (Chemistry) 606 $aChemistry, Analytic 606 $aEnvironmental chemistry 615 0$aSpeciation (Chemistry) 615 0$aChemistry, Analytic 615 0$aEnvironmental chemistry 676 $a577.14 676 $a577/.14 701 $aUre$b A.
