Abstract [en]

Environment Quality Standards (EQS) stated by the EU Water Framework Directive complemented by national EQS support the work of risk assessments of bioavailable metals in freshwater environments. In this paper, dissolved and truly dissolved (operationally defined by ultrafiltration) Cu, Ni, Pb and Zn concentrations were used to predict and evaluate the bioavailable metal fraction (calculated using Bio-met) in snowmelt and rainfall runoff samples from two urban catchments. The results show that the bioavailable Cu and Zn concentrations exceed the EQSbioavailable and that there is a metal by metal variation regarding the fraction of truly dissolved metals that is also bioavailable. The results indicate that the truly dissolved metal fraction is not a suitable surrogate for the bioavailable fraction for these metals.
