N1 - Funding Information:
This study was supported by Grants-in-Aid for Scientific Research (A) (No. 16201014) from Japan Society for the Promotion of Science (JSPS), and for Young Scientists (B) (Project No. 16780139) and “21st Century COE Program” from the Ministry of Education, Culture, Sports, Science and Technology, Japan, and “Material Cycles Modeling of Persistent Toxic Chemicals and its Policy Research Applications for Recycling and Waste Management” from the Waste Management Research Grants and “Japan-Korea Co-operative Joint Research Program on Endocrine Disrupting Chemicals” from the Ministry of Environment, Japan. Financial support was also provided by the Association for the Environmental Conservation of the Seto Inland Sea, Japan. Funding for the Hong Kong stranding program has been provided by the Agriculture, Fisheries and Conservation Department of the Hong Kong Government. PKSL was supported by a grant from the Hong Kong Research Grants Council (CityU1103/03M). One of the authors (Dr. Ueno) thanks the Grant-in-Aid for JSPS Fellows from Japan Society for the Promotion of Science for the fellowship provided to him during the course of this study.

N2 - Polybrominated diphenyl ethers (PBDEs) are one of the flame retardants widely used in plastics, textiles, electronic appliances, and electrical household appliances. In this study, PBDEs and organochlorine compounds (OCs) were determined in the archived samples from the Environmental Specimen Bank for Global Monitoring (es-BANK) at Ehime University. The blubber of cetaceans found stranded along the coasts of Japan, Hong Kong, the Philippines and India during the period from 1990 to 2001 were employed for chemical analysis to understand the present status of contamination and the specific accumulation of PBDEs. PBDEs were detected in all the cetacean samples analyzed, and concentrations were one or two orders of magnitude lower than for PCBs and DDTs. Concentrations of PBDEs ranged from a low value of 6.0 ng/g lipid wt. in spinner dolphin (Stenella longirostris) from India to a high value of 6000 ng/g lipid wt. in Indo-Pacific humpback dolphin (Sousa chinensis) from Hong Kong. No difference in PBDE levels between coastal and offshore species from Japan was observed, implying the existence of pollution sources in this region other than Japan. Highest concentrations of PBDEs were found in animals from Hong Kong, followed by Japan, and much lower levels from the Philippines and India, suggesting that developing nations may also have pollution sources of PBDEs. Geographical distribution of PBDEs in Asian waters was different from PCBs but similar to DDTs.
