Data from this experiment show that grass shrimp, Palaemonetes vulgaris, were acutely and chronically more sensitive to cadmium than the pink shrimp, Penaeus duorarum. Bioaccumulation of cadmium from water occurred at concentrations as low as 2 micrograms/l in P. duorarum and 7.9 micrograms/l in P. vulgaris. Pink shrimp, exposed to cadmium concentrations near LC50's, consistently developed blackened foci or blackened lamelae on the branchia. When the brine shrimp, Artemia, containing Cd were used as food, the transfer of Cd to grass shrimp was much less efficient than transfer of Cd directly from the water. To produce equivalent whole-body residues in the shrimp, about 15,000 times more Cd must be introduced in food than could be obtained from seawater.
