Abstract

The presence of PCDDs/DFs, PCBs and PAHs in the adsorbed or dissolved phases (depending on the leachate treatment process) was investigated in two landfills in Japan (Landfill M and Landfill N). The results of the investigations showed that, in general, persistent organic pollutants (POPs) having high Kow such as PCDDs/DFs and PCBs tended to exist in the adsorbed phase in both Landfill M and Landfill N. Furthermore, it was confirmed that their presence depended on log Kow by the appearance of PAHs.

摘要

在日本的两个垃圾填埋场（垃圾填埋场M和垃圾填埋场N）中，对吸附相或溶解相（取决于渗滤液处理工艺）中多氯二苯并对二噁英/多氯二苯并呋喃（PCDDs/DFs）、多氯联苯（PCBs）和多环芳烃（PAHs）的存在情况进行了调查。调查结果表明，一般来说，辛醇-水分配系数（Kow）较高的持久性有机污染物（POPs），如PCDDs/DFs和PCBs，在垃圾填埋场M和垃圾填埋场N中都倾向于存在于吸附相中。此外，通过PAHs的出现证实了它们的存在取决于log Kow。
