Chromatographic patterns of chlorinated pesticides (DDT, DDE, Aldrin, Dieldrin, and Endrin), and polychlorinated biphenyls (PCBs ; Kanechlor 200-600,and decachlorobiphenyl) obtained by reversedphase partition thin-layer chromatography (TLC) were compared with those obtained by adsorption thinlayer chromatography. The compounds were separated with two TLC systems ; liquid paraffin-silica gel/methanol-water and silica gel/hexane, and visualized on the layers by silver nitrate-UV irradiation. The pesticides were separated as sharp spots on either of liquid paraffin-silica gel and silica gel layers. The chromatographic patterns of the pesticides and PCBs on the former layers contrasted in Rf values with those on the letter layers. Only on the liquid paraffin layers, each Kanechlor was observed as slightly overlapped spots, more or less than 10,and the distribution of a polychlorinated biphenyl on the layer was dependent on the chlorine content in the individual components constituting the biphenyl. Thin-layer chromatography of both the pesticides and PCBs is useful for the confirmation of results obtained by gas-liquid chromatography.
