Soft shell clams were exposed over 28 days at 4C to single dose concentrations of 10, 50 and 100 ppm No. 2 fuel oil emulsion to simulate a potential winter oil spill. The hydrocarbon content of the water column was monitored on a weekly basis. Clams were removed and their histology examined after 28 days. The general effects of subacute oil exposure were characterized by a depletion of glycogen and a generalized leukocytosis particularly evident in the blood sinuses of the palluim and mantle membrane. The histological effects appeared to be dose dependent. The clams exposed to the 100 ppm oil emulsion had more frequent and noticeable histological differences from the controls.
