PHYTOREMEDIATION AND METHODS OF CONTROL FOR PCBS IN SOILS AND SEDIMENTS

摘要：

Various remediation alternatives for PCB-contaminated soils and sediments are discussed including removal actions, containment strategies and sediment covers, dredging and placement of material in confined disposal facilities or hazardous waste landfills, soil washing, composting, and stabilization of soils by lime or other binding agents. One promising alternative is phytoremediation – using plants to help clean-up the environment. New results show that hybrid poplars can uptake, bind, and degrade PCB congeners found in Chicago air. Hybrid poplar trees can take-up and metabolize selected PCBs congeners in hydroponic systems through their roots, and also effectively scavenge airborne PCB congeners through their leaves and bark, especially for those congeners with more than two chlorine substitutions.
