Cadmium was found to be lethal to sticklebacks at all concentrations from 100.0 to 0.001 mg Cd 1 –1 , in water of 103–111 mg 1 –1 hardness as CaCO 3 . The pattern of mortality as shown by the time‐concentration curve suggests that toxicity is not due to a single mechanism but changes with concentration. Fish were found to accumulate cadmium, the whole body levels increasing from 0.90 μg/g fresh weight at 0.001 mg Cd 1 –1 exposure concentration to 51.0 μg/g at 100 mg Cd 1 –1 . The concentration factor was shown to decrease with increasing exposure concentration from 0.51 at 100 mg Cd 1 –1 to 511 at 0.001 mg Cd 1 –1 . The plerocercoid parasite Schistocephalus solidus in the host's perivisceral cavity contained less cadmium than the tissues of its host.
