Web8 apr. 2024 · Typically, the organic form of mercury is considered more toxic, “whereas the mercuric [or ionized] mercury is less prone to being absorbed through the gut,” says Rand. However, Rand notes that ionized mercury can be converted into an organic form by bacteria in soil or ocean sediments – which is where at least 70 percent of the mercury … Webopen space between the bodies of mercury 4 and 5 thus separated and thereby produces an arc. This arc sets free ionized mercury vapor which has the effect of rendering the space between the electrode 6 and the mer cury 4 electrically conducting.
