Abstract
With the use of literary data, the things on sources of mercury pollution in Siberian region have been considered. With allowance made for present-day data about chemical interactions and with the results of original chemical analysis of crystals, steady atomic groups have been distinguished: [Hg4O] and [(Hg, M)4S] tetrahedra (M = Cu, Ag), [Hg6O2] r-octahedra, and [Hg3S2]n - the covalent bonded formations of different topology that can be preserved in natural processes, solid-phase and other transformations. This fact should be taken into consideration when discussing the forms of transport for mercury, lead, and alternative toxic elements in the environment.
