The report demonstrates that 5 mg/l of cadmium can be accumulated from seawater by adult oysters to levels exceeding 13 mg/l wet weight, a level found to cause illness in man. Bioaccumulation of cadmium concentrations greater than 13 mg/l wet weight occurs in about 40 weeks when exposed to 5 mg/l cadmium during winter, spring and summer conditions. Oysters accumulated more than half the total cadmium during the summer months.
