Abstract: We have made some experiments to see whether or not shell-fishes take up strontium, as strontium and calcium in the environmental sea water are increased slowly up to two time as dense as those in the general sea water. When the net amount of strontium in the environmental sea water is increased, though the increase varies to some extent, more strontium is taken up into the internal organs of the shell-fishes and then released. The process of absorption and release is repeated. However, the accumulation of strontium in the other organs such as shells and muscles cannot be observed. / 1. 二枚貝類を環境水中のSrとCa量を正常海水の2倍濃度まで徐々に増加させながら30日間飼育し,貝類諸器官中のSr,Ca量を原子吸光分析法によって測定した. 2. 内臓以外の器官中にはSr/Caモル%の変動はあまり見られず,内臓のSr/Caモル%は大きく変動するがSr及びCaの添加を終るとSr/Caモル%の変動は小さくなった. 3. 環境水中にSrのみ,SrとCa, Srを添加し途中からCaを添加した場合,内臓のSr/Caモル%の大きな変動は貝類のSr摂取が環境水中のSrの絶対量に関係し,共存するCa量にはほとんど関係しないように思われる.
