| Abstract: | Introduction Acidic and metal(oid)-rich topsoils resulted after 34 years of continuous operations of a copper smelter in the Puchuncaví
valley, central Chile. Currently, large-scale remediation actions for simultaneous in situ immobilization of metals and As
are needed to reduce environmental risks of polluted soils. Aided phytostabilization is a cost-effective alternative, but
adequate local available soil amendments have to be identified and management options have to be defined. |
