5WOOCT[Typical isomer pattern of dioxins observed in past bleaching process has been discovered from theseveral polluted soil and river sediment in Tokyo. In previous study, much attention was paid onchlorination to the river sediment as disinfection, so PCDFs similar to such an environmental
contaminated isomer profile could be formed in several water condition by the experiment. The
purpose of this study was further to examine the formation of PCDF including mono-, di- and tri-CDF
on various condition as a function of chlorination time. Consequently, the result indicated the lower
chlorinated PCDFs easily formed in all chlorine and pH condition and formation of the higher
chlorinated PCDFs was easily more advanced in acidity and high chlorine concentration. Analysis ofPCDF including the lower chlorinated compounds established the specific isomer mainly composed of
the 2,3,7,8-substituted isomer priorly formed. These data suggested several bleaching pattern could
be obtained because of advancing to higher chlorinated PCDF congener according to induction ofchlorine reaction.
