One of the most important current tasks in research on mercury behaviour in the environment is the increase of our knowledge concerning its cycles and balances in regional scales, including those for different types of regions. Such studies depends very much upon the completeness and quality information regarding local emissions and fluxes of mercury (Hg). However, the magnitudes of the anthropogenic emissions of Hg from different point and diffuse sources, and the fluxes due to natural emissions from the Earth surface are still very uncertain in major cases. Recently the main natural sources and anthropogenic emissions, as well as Hg budgets, were estimated for Siberia, the largest part of the Russia (about 10 million km 2). The huge size of this region makes the problem not only locally significant, but globally too.
