| Outline of Final Research Achievements |
Focusing on novel persistent organic pollutants (POPs) such as polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) and candidate POPs, their comprehensive contamination status, revelation of pollution sources, and temporal trend were studied mainly in developing countries. As a result, it was revealed that contamination by novel and candidate POPs was spread widely over the Asian coastal regions. In addition, it was suggested that the major sources of these contaminants in developing countries are derived from inappropriate recycling processes of electrical and electronic wastes (E-wastes) and end of life vehicles (ELV), and polybrominated dibenzofurans are unintentionally formed there and released into the environment. The temporal trend study using pelagic porpoise specimens stored in the Environmental Specimen Bank (es-BANK) at Ehime University implied prolonged pollution of novel POPs across the open ocean.
