The aim of the study is to investigate the existing form and the partitioning pattern of fluoride in krill (Euphusia superba) by analysing the fluoride and other elements in various part of krill, primarily to approach the potential concentrating mechanism and the effect of fluoride in krill on the geochemical characteristics of fluoride in the Antarctic ecoenvironment. The results of the study show that the amount of flouride in various part of krill has a considerable difference. Most of fluoride is concentrated in the carapace, up to 4028μg/g, and the head and legs, respectively 2724μg/g and 2828μg/g. The muscle contains the least flouride with amount of 226μg/g. The amount of fluoride in whole freeze-dried krill is averagely 1232μg/g, which indicates that the functional position of fluoride in krill is mainly located at the crust. Only a few of fluoride is found in the chitin of the carapaces (200μg/g), which exhibits that fluoride in the carapaces exists mostly in the form of the nonchitious
