THE PROBLEM OF OIL POLLUTION OF THE SEB

Aljakrinskaya (1966) showed that the filtering activities of mussels
Mytilus from the Black Sea were not slowed by crude oil in suspensions
up to 1%. The oil was accumulated in mucous strings and discharged
as pseudofaeces. Spooner (1968a, b) found that 0.4% suspensions of

which rejected some of the oil as pseudofaeces but ingested a proportion. The oil tended to " pond " in the gut but was eventually expelled
in true faeces. It seems unlikely that such globules could be digested
by the mollusc, but the incorporation of oil into faeces apparently made
it more readily available to micro-organisms.
