Disappearance of methylmercury and the lability of the methylmercury bond during volatilization was studied by the Incubation of submicromolar concentrations of 14CH3HgCl and CH3203HgCl for 96 h in solutions routinely encountered in environmental and laboratory situations. Media with high ionic strength, 0.5 M NaCl and artificial sea water lost more mercury than deionized water, tap water, water from fish holding tanks, basic and acidic solutions, and phosphate buffered saline. Loss from the former solutions appears to be a continuous process while occurring in the first few hours in the latter. Total loss did not exceed 20 % in any experiment and was due primarily to mercury in the inorganic form.
