CHAPTER 15 . Toxic Effects of Organometallic Compounds towards Marine Biota

The study evidenced that Meretrix lusoria, Tapes japonica and Tresus keenae contain not only arsenobetaine, but also the arsenosugar derivative reported in Fig. 15.2a,
while Mytilus edulis, Mytilus coruscum, Cassostrea gigas, Anadara broughtonii, and
Corbicula japonica contain either one or both of the arsenosugars of Fig. 15.2a,b. Since
these bivalves are plankton-feeders, one can hypothesize that algae are one of the possible sources of the above-mentioned arsenosugars, while arsenobetaine could be erTable 15.1. Arsenic species in bivalves, adapted from Shibata and Morita (1992)
