抄録

Concentrations of persistent organochlorines (OCs), such as polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs), hexachlorocyclohexane isomers (HCHs), hexachlorobenzene (HCB), and chlordane compounds (CHLs) in the muscle and liver tissues of feral mongooses from the Okinawa Island were measured, in order to understand the contamination status by these contaminants in the Southwest Islands, Japan. The lipidnormalized concentrations of each compound were similar between the muscle and liver tissues of mongooses from the rural area, and were in the order of PCBs ＞CHLs ≒DDTs ＞HCHs ≒HCB. The concentrations of CHLs and DDTs in the mongoose muscles from the residential areas were higher than those from the rural area. In the mongooses from all the areas, the predominant CHL compounds were oxychlordane and trans-nonachlor, while p,p’-DDE was dominant among DDTs. Higher concentrations of PCBs were accumulated in the mongooses from an area around a contaminated tidal flat and from another area which includes US military facilities, when compared with those from a residential area. The PCB congeners which occupied more than 5% of all the congeners detected in the mongoose tissues were PCB138, 153, 170, 180, 187, and 194 in both of the two highly contaminated areas, but their proportions were different from each other.
