The guppy (Lebistes resticulatus) and coontail (Ceratophyllum demersum) were exposed to water containing 203Hg-labeled ethylmercuric chloride (EMC). The EMC uptake was related to the time of exposure and the concentration of EMC. Highest concentration of 203Hg was found in the internal organs of the guppy and the body has the least concentration. The biological half-life of 203Hg from EMC was approximately between 20 and 23 days. Both organisms are capable of converting the absorbed EMC to inorganic mercury with the coontail having a slightly higher rate (34%) of conversion as compared to the average of 29% for the guppy during a seven-day period.Both organisms accumulated slightly more MMC than EMC from a solution containing the same concentration of EMC or MMC. There was very little conversion of MMC to inorganic mercury by the guppy, indicating the stability of MMC in this organism. The absorbed MMC molecule was also more stable than the EMC in the coontail.
