It was found that livers of all fish species, particularly pelagic species, studied were capable of transforming mercuric ion into methylmercury in vitro. The factors involved in the process of methylmercury formation from Hg/sup 2 +/ ion in the fish liver were studied. The methylation activities were not destroyed by either heat or uv and visible light irradiation treatments. It was thus concluded that the reaction(s) studied here was not mediated by methylcobalamine. Mersalyl, a SH inhibitor, could, however, abolish most of the methylation reaction.
