The considered scope is focused on the classic global with mainly centralized assets and decisions, since also considered production resources are treated as virtually global sources. 

In the considered case, each production is managed as a global source, Therefore, production is globally concentrated and there is lack of relationship between the production site and the region where it is located. 

This value characterizes the upper level of relative scattering of estimated elements concentration in all the considered snow samples, which is associated both with estimation errors in groups 1-3 and natural variation of the elements abundance in samples. Thus, the results of successive testing of ypotheses Ht -H3 allow us to conclude that the basic hypothesis Hb is true and only global source of chemical contamination exists on the territory of Karabash.

The atmospheric deposition rate in this midcontinental area, which has increased by a factor of about 3.7, suggests that natural Hg concentrations were only about 25% of modern levels. Current estimates of recent increases in global atmospheric Hg support this conclusion, and indicate that increased anthropogenic Hg emissions, rather than enhanced removal by atmospheric oxidants, are responsible for elevated Hg deposition. Moreover, the increase appears to be relatively uniform across our study area, implying regional if not global sources for the Hg falling on these remote sites. 

Sulphur dioxide is both emitted into the troposphere and also formed during oxidation of dimethyl sulphide (DMS) and other sulphur containing species produced in the biosphere. Important sources of atmospheric S02 are volcanoes. However, the major single global source is probably the combustion of sulphur-containing fossil fuels. In the stratosphere there are two important sources of sulphur dioxide, i.e. injection by volcanic eruptions and oxidation of carbonyl sulphide (COS), which is transported from the troposphere. 

Biomass combustion is a major global source and may even be the major source of atmospheric CH3C1 (223, 282-288). These studies indicate that CH3C1 production is maximized in low intensity fires, from incomplete combustion, and by increased chloride concentration. It is estimated that six billion tons of biomass are consumed...

Globally, sources for worldwide generation of electricity in 2007 included about 16% hydroelectric 16% nuclear and 2% renewables including waste, wind, geothermal and solar. 

Meybeck, in a recent (1987) comprehensive article on the global sources of dissolved constituents in world s rivers, arrived at a balance more similar to the one presented here. He presented a compilation of various authors estimates of the sources, given here in Table 9.10. There is seemingly good agreement between the works of Holland (1978), Wollast and Mackenzie (1983 this book), Berner et al. (1983), and Meybeck s latest work (1987). Table 9.10 provides the reader with some idea of the history of source estimates for the dissolved materials of rivers and their range of values. 

On a global scale, natural emissions of reduced sulfur compounds account for about 50% of the total sulfur flux into the atmosphere (1-3). Hence, it is important to understand the natural sulfur cycle in order to establish a "base line" for assessing the significance of anthropogenic perturbations (primarily SO2 emissions). Dimethylsul-fide (DMS) is the predominant reduced sulfur compound entering the atmosphere from the oceans (4-9), and DMS oxidation represents a major global source of S(VI). The atmospheric oxidation of DMS can be initiated by reaction with either OH or NO3. In marine environments, however, NO3 levels are typically very low and DMS is destroyed primarily by OH ...
