Abstract

Arsenic concentrations and species in tissues of nine species of Australian bivalve mollusks from South-East Australia are presented. Arsenic concentrations were variable: whole tissues (18-109 mg/kg), viscera (18-158 mg/kg), muscle (1-42 mg/kg) and gills/mantle (19-60 mg/kg). Organisms living in sediments such as Tellina deltoidalis have higher arsenic concentrations. The suspension feeding omnivores contained mostly arsenobetaine and traces of dimethyl arsenate, arsenocholine and tetramethylarsonium ion. The deposit feeders contained less arsenobetaine and appreciable amounts of inorganic arsenic and arsenosugars. Arsenic concentrations and species are organism specific and determined by a variety of factors including exposure, diet and physiology.
