| Research Abstract |
POPs candidates, short-chain chlorinated paraffins, organofluorine compounds, are detected at low concentrations by using a chemical ionization mass spectrometry.
The measurements were performed for samples that has been collected in Kyoto University biological specimen bank. Dietary intake, geographic distribution in Japan, and the source of exposure were evaluated. There was no change over the past decade in intake of organofluorine compounds in Japan. Serum levels showed the similar composition ratio of the homologues and correlation between seafood intake. Levels in breast milk samples revealed the exposure of the infant. For short-chain chlorinated paraffins, it is detected in the food duplicate samples, especially in China. In the breast milk samples, chlorinated tridecane was observed in China, and some chlorinated undecane in Japan.
