The transfer of Cd, Cu, Ni, Pb, and Zn was evaluated in a soilplant (lettuce, Lactuca sativa )invertebrate (snail, Helix aspersa ) food chain during a microcosm experiment. Two agricultural soils, polluted and unpolluted, were studied. Lettuce was cultivated for eight weeks before introduction of snails into the microcosms (Msnails).

Live ChatInteractions between Cd, Cu, Pb, and Zn and four different
The chemical associations of Cd, Cu, Pb, and Zn in four mine soil samples from the Amizour Bejaia Pb/Zn mine (Algeria) have been investigated by a five step sequential extraction procedure. Although Cd preferentially binds to carbonates, Cu, Pb, and Zn are mainly associated with the organic and reducible fractions. Batch adsorption experiments with either mono or multi metallic solutions are

Cu and Zn (Hartley et al., 2004). Warren et al., 2003, Warren and Alloway, 2003 observed increased plant uptake of other contaminants including Cu, Zn and Pb in soil amended with Fe(II) sulfate and lime. The authors explained that there was an insufficient amount of lime added and suggested a ratio of lime/Fe oxide necessary for maintaining

In general, higher concentrations of Cu and Zn remained complexed with the dissolved fraction, while Pb was mostly complexed with particulate materials. Chemical equilibrium modeling (MINEQL+) showed that Zn(2+) and Cd(2+) dominated the labile species, while Cu and Pb were complexed with carbonates.
