Abstract
Large spoils of metal-rich filtercake from the Port Kembla BHP steelworks were characterised by certain physical, chemical and biological parameters. The vegetation was assessed for potential metal hyperaccumulators and the presence of arbuscular mycorrhizae in the rhizospheres. Fresh filtercake ( 4 yr). Among the naturally colonising plants, Ricinus communis and Sonchus oleraceus are regarded the most suitable options for zinc and cadmium removal, respectively. Arbuscular mycorrhizal infection (particularly with Glomus and Gigaspora strains) should be promoted for optimum soil reclamation.
