Abstract: | Mass food poisoning incidents, called Yusho and Yu-Cheng, were caused by the ingestion of rice oils which had been contaminated with polychlorinated biphenyls (PCBs), polychlorinated dibenzofurans (PCDFs) and polychlorinated quaterphenyls (PCQs). This paper reviews the formation of toxic PCDFs in the rice oil from PCBs, intakes of PCBs, PCDFs and PCQs by the patients and the behavior of PCBs, PCDFs and PCQs in the human body. |
