摘要: Abstract The problem of copper (Cu) pollution in riverine ecosystems is world-wide and has significant environmental, eco-toxicological, agricultural relevance. We assessed the suitability effectiveness application rate 1% activated charcoal, bentonite, biochar, cement kiln dust, chitosan, coal fly ash, limestone, nano-hydroxyapatite, organo-clay, sugar beet factory lime, zeolite as soil amendments together with rapeseed bioenergy crop a possible remediation option for heavily Cu polluted floodplain (total Cu=3041.9 mg kg−1) that very high proportion sorbed/carbonate fraction (484.6 mg kg−1) potential mobile (1611.9 mg kg−1). Application changed distribution among geochemical fractions: alkaline materials lead to increased carbonate bounded acid rhizosphere zone might cause release this Cu. Thus, mobilization uptake by were compared control (except organo-clay) under prevailing conditions.
