Bioavailability of Adsorbed Cd on Typical Oxides of Sediment in Phragmites australis
沉积物中典型氧化物矿物吸附的镉对芦苇的生物有效性研究

Effects of different chemical speciation(e.g.adsorbed on different metal oxides) in environment on Cd bioavailability were studied.Goethite,magnetite,gibbsite,alumina,and manganese oxide were chosen as representatives of oxides commonly present in sediment.In cultivar system,Hoagland solution was used as nutrition supply,and single metal oxide adsorbed Cd as the only source of contamination and Phragmites australis was induced to study Cd bioaccumulation.After 45-day cultivation,Cd was uptake and accumulate...
