✦ Synopsis

Trimethyl(carboxymethyl)arsonium zwitterion (arsenobetaine) is virtually ubiquitous in marine animals consumed by man. Experimental work on the transformation of arsenate to arsennbetaine in the marine environment is reviewed. Current evidence favors the conversion of arsenate to dimethyl(ribosy1)arsine oxides by algae, and the microbially mediated transformatinn of dimethyl(ribosy1)arsine oxides to arsenobetaine or to its immediate precursors in the sediments. In- formation about the transfer of arsenobetaine from the sediments to marine animals is lacking.

We have studied the cytotoxicity in vitro of tetramethylarsonium hydroxide (TetMA-OH), which is found in some marine animals, in various murine immune effector cells, including splenocytes, thymocytes, Peyer's patch (PP) lymphocytes, peritoneal macrophages (PMs) alveolar macrophages (AMs) and bone-m
