title: [Identification of polychlorinated phenyldibenzofurans (PCPDFs) in the casual rice oil associated with yusho].
abstract: The polychlorinated dibenzofuran (PCDF) fractions obtained from the causal rice oils associated with yusho were analyzed by capillary column gas chromatography with electron capture detection (ECD/GC) and capillary column gas chromatography-mass spectrometry (GC/MS) in negative chemical ionization (NCI) mode. The GC/MS analysis revealed that the PCDF fraction contained, in addition to PCDF congeners, penta-to octa-and probably nona-chlorinated phenyldibenzofuran (PCPDF) congeners in comparison with retention times and NCI mass spectra of PCPDF standards. The ECD/GC analysis showed the presence of at least 30 different PCPDF congeners in the rice oils.
