✦ Synopsis

Study o] the uptake, concentration and metabolism o] strontium 85 by the decapod crustacean Carcinus n~aenas

Strontium is absorbed and retained by Carcinus maenas L. The variations of the specific activity rates due to the retention of ssSr have been studied for the whole animal as a function of its size and the activity of the contaminating water. The same study has been carried out as a function of the stages of the intermoult cycles for both the whole animal and the organs and tissues likely to affect the uptake, storing, or further metabolism of strontium in the hepatopanereas, hypoderm, blood, gills, muscle and exoskeleton. On the basis of the results, assumptions are made on the respective part played by these organs or tissues in the processes studied.
