Abstract: California sea mussels (Mytilus californianus) of 2 to 5 cm length were collected from intertidal areas in Pacific Grove, California, during May. they were placed in various dilutions of primary unchlorinated sewage and their respiration was measured. Results indicate that sewage causes changes in respiratory activity, and that high concentrations are extremely toxic. An attempt was made to isolate the toxic factors but proved unsuccessful. Data for the excretion of dissolved inorganic phosphate by the mussels are also presented.
