Study on chemical forms of fluorine enrichment of Antarctic krill

摘要

The different forms fluorine in different parts of molting process of krill was analyzed by culture of Antarctic krill (Euphausia superba). The results show that fluorine amount in cuticle is up to 90/100 of total in the krill. During the krill molting process, the fluorine content in cuticle and muscle varies alternatively. This is to say, the fluorine content in new cuticle and muscle is much lower after molted, the fluorine in krill comes from seawater by biological absorption of the krill, and the fluorine absorbed by krill lost with the old cuticle at the end stage of molting process.
