Two species of fishes (n=52; tilapia and mullet) from industrialized and urbanized areas of Okinawa Island (Manko-Noha river, Hija river and Shikaza river) and from a remote area of Ishigaki Island (Anparu mudflat), Japan were collected between August 2005 and July 2006, and analyzed for five organochlorine compounds (OCs), viz., DDTs, PCBs, CHLs, HCHs and HCB. Concentrations and the contamination patterns of OCs in fishes varied between locations. Considerable residue levels of OCs, especially CHLs and DDTs were found in both fishes from the main Okinawa Island. These levels were relatively higher than the reported values for seafood from Japanese coasts, indicating that even now pollution sources of these contaminants still exist in this region. On the other hand, lower concentrations of OCs were detected in fishes from Ishigaki Island waters than those of other Japanese coastal waters, suggesting that this region is less contaminated by OC contaminants.
2005 年 8 月至 2006 年 7 月期间，采集了来自日本冲绳岛（万座毛河、比嘉河和识名崎河）工业化和城市化地区以及石垣岛（安房滩涂）偏远地区的两种鱼类（罗非鱼和鲻鱼）（n=52），并分析了 5 种有机氯化合物（OCs），即滴滴涕、多氯联苯、氯仿、六氯环己烷和六氯苯。鱼类中 OCs 的浓度和污染模式在不同地点有所不同。在主冲绳岛的两种鱼类中都发现了相当高的 OCs 残留水平，特别是氯仿和滴滴涕。这些水平相对高于日本沿海海域海产品的报告值，表明即使在现在，这些污染物的污染源仍存在于该地区。另一方面，在石垣岛水域采集的鱼类中 OCs 的浓度低于其他日本沿海海域，表明该地区受 OC 污染物的污染程度较低。
