A comparative study is presented of the transfer of HgCl/sub 2/ and CH/sub 3/HgCl between a species representative of the ''producer'' level -- Chlorella vulgaris -- and a primary consumer -- Daphnia magna. The experiment was carried out at two temperatures, 10 and 18/sup 0/C, and the concentration of metal in the environment was 1 ..mu..g.l/sup -1/ (1 ppb). Results seem to indicate that the two contaminants, which are first introduced into the environment and then fixed by the unicellular algae, retain their specific property of crossing the digestive barrier of the consumer link.
