TOXIC METAL SPECIATION SCHEME FOR WATER AND SEDIMENT FROM AN URBAN STORM SEWAGE

Résumé

Taking into account available metal speciation schemes for river water and sediments, we have developed a scheme designated to evaluate the metal toxicity of urban storm water and sediment samples and containing 3 dissolved and 5 particulate fractions. Reagents and procedures for determination of total particulate metals have been compared, together with ion exchangeable and carbonate fractions. This speciation scheme was applied to urban storm sewage samples : it was observed that dissolved lead, zinc and cadmium were mainly concentrated in the labile fraction and that each particulates metal was distributed differently.
