Leaching behavior of persistent organic pollutants (POPs) in shredder
residues.

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.
