The major sulphur fluxes of both natural and anthropogenic origin have been assessed by generalization of the results of our studies and data available in the literature. Annually about 120 Tg S are extracted by man from the lithosphere in fossil fuels and sulphur-containing raw materials for the chemical industry. Of this amount 70 Tg S are emitted to the atmosphere with the products of fuel c...

Biogeochemical processes in rivers are controlled by biological, chemical, geomorphic and hydrologic interactions. These interactions produce variable redox environments wherein microorganisms derive energy and synthesize tissue using oxidation-reduction reactions associated with several elements including C, N, P, S, and to a lesser extent Fe and Mn. Biogeochemistry of river water and surface ...

Eucalyptus trees may translocate Au from mineral deposits and support the use of vegetation (biogeochemical) sampling in mineral exploration, particularly where thick sediments dominate. However, biogeochemistry has not been routinely adopted partly because biotic mechanisms of Au migration are poorly understood. For example, although Au has been previously measured in plant samples, there has ...
