The metabolism of methoxyethylmercury salts.


ABSTRACT: The metabolism of methoxy[(14)C]ethylmercury chloride in the rat has been investigated. After a single subcutaneous dose a small proportion is excreted unchanged in urine and a larger amount in bile with some resorption from the gut. The greater part of the dose is rapidly broken down in the tissues with a half-time of about 1 day to yield ethylene and inorganic mercury. Ethylene is exhaled in the breath and the mercury migrates to the kidney and is excreted in urine. A small proportion of the dose appears as carbon dioxide in the breath and about 12% in urine as a mercury-free metabolite. It is possible that the breakdown of methoxyethylmercurychloride to ethylene and inorganic mercury is not catalysed by an enzyme system.
