众所周知，有些废物含有持久性有机污染物(POPs)，如PCDD/DFS和多氯联苯。然而，由于这些化学物质的浸出性较低，它们的浸出行为并没有得到那么多的关注。另一方面，来自汽车和电器的碎纸机残渣主要由塑料组成，如聚氯乙烯，其中含有包括DEHP在内的添加剂。在这项研究中，进行了粉碎机残渣的含量分析和有无表面活性物质的浸出试验。结果，汽车和电器的碎纸机残留物含有ppm级的多氯联苯和一定量的多氯二苯并二恶英/二恶英。表面活性剂类物质增加了POPs的浸出浓度。即使使用蒸馏水，DEHP也有相当大的渗出量。
It is well known that some kinds of waste contain persistent organic pollutants (POPS) such as PCDD/DFs and PCBs. Leaching behaviors of these chemicals, however, have not been focused so much because of their low leachability. On the other hand, shredder residues originated from automobiles and electric appliances consist mainly of plastics, such as PVC, which contain additives including DEHP. In this study, contents analyses and leaching tests with and without surfactant-like substances for shredder residues were conducted. As a result, shredder residues from automobile and electric appliance contained PCBs in ppm level and a quantity of PCDD/DFs. Surfactant-like substances increase the leaching concentration of POPs. DEHP also leached out considerably even though using distilled water.
