Description
Summary:The cause of the concentration 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 discussed. Results show that as an inorganic medium the cuticle of krill has the second concentrating function and action to fluoride after moulting, which has nothing to do with the biological action of the krill. The fluoride is concentrated from seawater, which is prosecuted mainly in the form of ion exchange.
