Recent estimates indicate that of the approximately 200000 tons of mercury emitted to the atmosphere since 1890, about 95% resides in terrestrial soils, about 3% in the ocean surface waters, and 2% in the atmosphere (Expert Panel on Mercury Atmospheric Processes 1994). Some 20-30% of the current oceanic emissions are from mercury originally mobilized by natural sources (Eitzgerald and Mason 1996). Similarly, a potentially large fraction of terrestrial and vegetative emissions consists of recycled mercury from previously deposited anthropogenic and natural emissions (Expert Panel on Mercury Atmospheric Processes...

In 1995, approximately 1900 metric tons of anthropogenic mercury entered the atmosphere (mostly 75%) from the combustion of fossil fuels. About 56% of global mercury atmospheric emissions came from Asian countries, with Europe and North America combined contributing less than 25% gaseous elemental mercury (Hg) comprised 53% of total atmospheric emissions, gaseous Hg+ 37%, and particle-associated mercury the remainder. 

For a liquid with half the density of mercury, atmospheric pressure will generate a column twice as high as that generated fiir mercury. The column will be 750 mm x 2 = 1500 mm 1.5 X 10 atm 0.9886 atm...
