Abstract:

The Cause for the accumulation of fluoride in Antarctic krill is studied by the analysis of the characteristics of fluoride change in the cuticle of the krill before and after moulting. Associated with other related information, the source and accumulating mechanism of fluoride in krill are also disscussed. Results show that as an inorganic material the cuticle of krill has the second absorption function and action on fluoride after it is moulted, which has nothing to do with the living activity of the krill. The fluoride is accumulated from seawater, which is prosecutedmaily in the form of ion exchange.
