ACCUMULATION, FRACTIONATION AND RELEASE OF OIL BY THE INTERTIDAL CLAM 'MACOMA BALTHICA'
The bivalve mollusc Macoma balthica accumulated hydrocarbons during 180 days of continuous exposure to Prudhoe Bay crude oil in seawater dispersions with nominal concentrations of 0.03, 0.3, and 3.0 mg 1-1. The mollusc's ability to concentrate oil from sea-water increased with decreasing oil-in...
