Ecochemical Approach Using Mercury Accumulation of Antarctic Minke Whale, Balaenoptera bonaerensis, as Tracer of Historical Change of Antarctic Marine Ecosystem During 1980—1999
The biiology and ecology of the Antarctic minke whale in the Antartic Ocean have been studies and informatiuon on age, food habits, migration and reproductive activities are available (Ohsumi et al. 1970; Ohsumi and Masaki 1975; Masaki 1979; Kato 1983; Kato et al. 1984). Also, since the whale is a long-life marine mammal (about 50 years), feeding mainly on Antartic krill, this animal may be useful as an 'indicator species' to learn complex long-term accumulation characteristics of heavy metals and organo halogen compounds in the Antarctic marine ecosystems (Honda 1985).
