Abstract
Metal speciation methods which identify potentially bioavailable and/or geochemically mobile metal fractions in polluted waters are discussed. Two approaches to monitoring bioavailable metal are presented. These include a comparison between Chelex Removable metal concentrations and water quality standards and the determination of bioavailable metal uptake rates by a Dialysis with Receiving Resins technique. Metal species mobilisation and transport processes through a gullypot system have been identified by the application of a physico-chemical speciation scheme. Metal species transfer between phases and fractions is affected by acid rain mobilisation, free and weakly complexed metal ion reaction, pH/surface area dependent suspended solid metal transport and gullypot sediment maturation.
