The Occurrence and Retention of Dimethyl-β-Propiothetin in Some Filter-Feeding Organisms
Determinations of dimethyl-β-propiothetin (DMPT) levels are reported for 10 filter-feeding organisms, 1 browsing mollusc, 1 carnivorous mollusc, and 1 crustacean. Mature oysters, scallops, and the pteropod Limacina helicina showed high (ca. 0.1 mg/g) DMPT levels, mussels showed generally lower level...
