source of contamination to river systems and may significantly hinder the achievement of
European Union Water Framework Directive objectives. Redox-transitional zones that form
along metal contaminated river banks as a result of flood and drought cycles could cause
biogeochemical changes that alter the behaviour of polyvalent metals iron and manganese
and anions such as sulphur. Trace metals are often partitioned with iron, manganese and …
