Abstract
This paper gives an overview of the problems related to metal speciati on measurements and interpretation, as well as the criteria which shou ld be used for the development of in situ techniques. Three promising methods are examined in greater detail: diffusion gradients in thin fi lms (DGT), integrated diffusion in gel and voltammetry and the support ed liquid membrane (SLM) preconcentration technique. The present state of the art in this field is discussed with suggestions for future res earch directions.
