摘要: The mushroom cultivation industry produces a huge amount of spent compost (SMC), wide world agricultural organic waste which causes serious environmental problems. However, this cheap could be useful in the remediation contaminated soils. aim work was to assess potential SMC combination with native shrub Atriplex halimus, phytoremediate two mine soils Cd, Pb and Cu. Firstly, minimize metal availability soil, optimal doses were determined. Secondly, phytoremediation assay greenhouse conditions carried out test effects A. halimus at different doses. results showed ability reduce soil acidity, mobility metals enhancement growth. promoted immobilization root decreased translocation from roots shoots. amendment produced phytostabilization assayed. In conclusion, represents an adequate solid can adverse impact caused by high acid
