... as the test material. The marine bivalve, Mytilus edulis , was exposed to suspended dredged material for 28 days in a flow-through exposure system. Exposed organisms were then extracted and analyzed for bioavailable, low-polarity contaminants by gas chromatography/mass spectrometry (GC/MS). All separable GC...
