The accumulation of 137‐caesium from fresh water by alevins and fry of Atlantic salmon and brown trout
The accumulation of 137‐caesium from water by alevins and fry of Atlantic salmon and brown trout was studied, At ‘normal’ pH (∼7.4), input rates (k WF ) and equilibrium concentration factors (CF eq ) of 137‐caesium were four to five times greater in both species of alevins than those in the fry.
