| Research Abstract |
In this report, we investigated those of Co-PXBs in the ambient air and sediments as environmental samples, and market foods and breast milk as biota samples, and further flue gas from incinerators as contamination sources. Then, we compared each contribution ratio for total actual concentration by PCDDs/DFs, Co-PCBs, PBDDs/DFs, PXDDs/DFs and Co-PXBs formed by pyrolysis or photolysis of PBDEs in lab-scale experiment, and estimated the Co-PXBs contamination sources. On the basis of results, we tried to clarify the real situation of Co-PXBs contamination and demonstrate their contamination sources in Japan.
