Extract

In 1968 it was discovered that mercury could be biomethylated to give methylmercury as the major product (Wood, Kennedy & Rosen, 1968; Jensen & Jernelöv, 1969). This discovery has proved to be important in two respects: (a) it provided us with the recognition that biological systems are capable of synthesizing very toxic organometallic compounds from relatively innocuous inorganic precursors, and (b) it opened the door to the study of organometallic compounds produced by biological mechanisms in the aqueous environment.
