The organisms studied were the green-lipped
mussel (Perna viridis), the rock oyster (Crassostrea
commercialis), the bloody cockle (Andara granosa), the
short neck clam (Paphia umdulata) and the moon scallop
(Amusium pleuronectes). The metal levels appear quite
low by comparison to these same species from elsewhere
in the world (Hungspreugs and Yuangthong, 1983;
Philip and Muttarasin, 1985).
