Abstract

The potential for plants to minimize leachate volume and reduce cyanide and fluoride concentrations in groundwater was evaluated. High fluoride and soluble salts in the leachate induced chlorosis or necrosis in the leaf margins on green ash (Fraxinus pennsylvanica), yellow poplar (Liriodendron tulipifera), and bald cypress (Taxodium distichum). Hybrid willow (Salix Willow hybrid), sycamore (Platanus sp.), and black willow (Salix nigra) had high rates of transpiration and root growth during the study period. Cyanide in the leachate was removed by plant metabolic processes whereas fluoride accumulated in the leaves. Cyanide and fluoride in landfill leachate can be decreased through phytoremediation.
