title: Influence of complexing agents and surfactants on metal speciation analysis in road runoff.
abstract: A combination of medium exchange and sample acidification techniques is used to enable the calculation of the individual effects of complexing agents and surfactants on the deposition and stripping steps in anodic stripping voltammetry for copper, lead and cadmium in road and urban runoff. A simple acidification procedure is presented for determination of the toxic fraction.
