Outline of Final Research Achievements

Japanese Red-crowned crane inhabits the marsh in the eastern Hokkaido and it is classified as an endangered species. Nowadays, it lives near human beings and it is concerned that Red-crowned cranes are exposed to more anthropogenic chemical substances. Therefore, it is important to investigate the exposure levels of the chemicals for their protection. In this study, we determined the concentrations of persistent organic pollutants (POPs) in red-crowned crane muscle tissues and the concentrations were not high that their toxicities need to be considered. Furthermore, hydroxylated metabolites of polycyclic aromatic hydrocarbons (PAHs) excreted in the bile of the crane were successfully identified and quantified by using a developed analytical method. The biliary metabolites should be useful for the surveillance of exposure to PAHs.
