In Hg-resistant bacteria that are resistant to organic forms of Hg such as phenylmercuric acetate and methylmercury chloride, lyases are involved in the fission of the C-Hg to form Hg + and benzene or methane, and the enzyme has been partly purified (Schottel 1978). The Hg + may then be reduced to nontoxic Hg°. The situation under anaerobic conditions for sulfate-reducing bacteria is complicated by the possibility of both methylation and demethylation in the same strain (Pak and Bartha 1998), plausibly by operation of the acetyl-CoA pathway (Choi et al. 1994 Ekstrom et al. 2003). Under anaerobic conditions, demethylation, though not methylation, has been reported for a methanogen (Pak and Bartha 1998).

Stoeppler and Matthes [44] have made a detailed study of the storage behaviour of methylmercury and mercuric chloride in seawater. They recommended that samples spiked with inorganic and/or methylmercury chloride be stored in carefully cleaned glass containers acidified with hydrochloric acid to pH 2.5. Brown glass bottles were preferred. Storage of methylmercury chloride should not exceed 10 days. 

May et al. [45] used radiochemical studies to ascertain the behaviour of methylmercury chloride and mercuric chloride in seawater under different storage conditions. The application of 203Hg unambiguously revealed that the loss of mercury observed upon storage of unacidified seawater samples in polyethylene bottles was due to adsorption and to the diffusion of metallic Hg (Hg°) through the container wall. 

Females fed diets for 12 weeks containing 80 mg Pb/kg ration (as lead acetate) alone or in combination with 8 mg Hg/kg (as methylmercury chloride), or 80 mg Cd/kg ration (as cadmium chloride), ora mixture of Pb, Hg, and Cd Renal corpuscles of ducks fed Pb, Fig, or Cd alone or in two-way combinations had minor ultrastructural changes when compared to controls. The diet containing all three metals caused marked ultrastructural changes in kidney 40...

Ethylmercury produced about equal amounts of mercury vapour and an uncharacterized volatile ethylmercury compound, while methylmercury chloride and methylmercury dicyanamide both produced an uncharacterized methylmercury compound plus some mercury vapour. 

Total mercury is determined in soils containing phenylmercury acetate and or ethylmercury acetate using the method described by Polley and Miller [31]. Total mercury is determined in soils containing methylmercury chloride and methylmercury dicyanamide by the method described by Kimura and Miller [32], Kimura and Miller [30] present chemical data on the nature of residual mercurials in soil and in the atmosphere surrounding the treated soil to further elucidate the phenomena of degradation in soil.

Samples of atmospheric mercury were obtained by pre-concentration of mercury on columns of graphitised carbon black (Carbotrap). The columns, at ambient temperature, retained mercury vapour and alkylmercury compounds (Bloom and Fitzgerald, 1988). Methylmercury chloride, ethylmercury chloride and dimethylmercury were held on the column at temperatures as high as 29°C and air flow rates as high as 790cm3min 1. At high flow rates and high temperature,...
