title: Heavy metal complexation in polluted molluscs. III. Periwinkles (Littorina littorea), cockles (Cardium edule) and scallops (Chlamys opercularis).
abstract: The accumulation of cadmium, zinc and copper by environmentally contaminated periwinkles, cockles and scallops has been studied by gel permeation chromatography of water-soluble extracts of the shellfish. Three distinct low mol. wt. (less than 3000) zinc complexes were separated from periwinkle extracts. Copper and cadmium were present as a single low mol. wt. species which is apparently responsible for the elevated copper levels in Littorina littorea.
