Leaching characteristics of PCDDs/DFs and co-PCBs from landfills containing municipal solid waste and incineration residues.

抄録

The concentrations of PCDDs/DFs and co-PCBs in leachate from disposal sites contained municipal solid waste and incineration residues were average 48.006 pg/l(16.220-959.509 pg/l) and 85.553pg/l (22.720-2,179.683 pg/l), respectively. The major congeners of PCDDs/DEs and co-PCBs in leachate were OCDD (approximately 70%) and 2,3',4,4',5-PeCBs (approximately 50%), respectively. The concentration of PCDDs/DFs in leachate decreased with increasing the ratio of non-combustible matter including incineration residue to total wastes in landfill.
