What is the difference between ethyl mercury and methyl mercury?
Methyl mercury is more potent; it accumulates in the body because the time taken for the body to eliminate it (know as the ‘half-life’) is about 50 days. Ethyl mercury (in thiomersal) does not accumulate in the body to such an extent, because its half- life is only about 7–10 days.
