Remediation of strongly acidic mine soils contaminated by multiple metals by plant reclamation with Jatropha curcas L. and addition of limestone
|
Abstract:
In a greenhouse pot experiment,the dose-response effects of limestone addition (mass fractions 0,0.1%,0.25%,0.5% and 1.0%) on the growth performance and metal uptake characteristics of Jatropha curcas L. grown on different multi-metal contaminated,strongly acid soils from Dabao Mountain mine were studied. Factors suppressing plant growth as well as the feasible dosage of limestone are also discussed. In the soils with lower levels of pollution,high bio-availabilities of Cu and Pb appeared to be the primary ...
