Evidence for terrigenic sf 6 in groundwater from basaltic

Abstract. Measurements of the concentrations of dichlorodifluoromethane (CFC-12), tritium (3H), and sulfur hexafluoride (insulating gas) in groundwater from basaltic aquifers in Jeju Island, Korea, demonstrate a terrigenic source of sf 6. Using a lumped-parameter dispersion model, groundwater was identified as young water (<15 years), old water with negligible CFC-12 and 3H, and binary mixtures of the two.

In particular, it has become known as a major exporter and an industrial leader in many sectors, including electronics, cars, shipbuilding and steel. Following decades of authoritarian rule, South Korea held its first free parliamentary election in 1988. Its two major political parties are the conservative United Future Party and the ruling liberal Democratic Party, with Moon Jae-inserving as the nation’s current Democratic president. The next legislative election, in which all 300 members of the country’s national assembly will be chosen, is set to take place on 15 April.

Atmospheric sf 6: Trends, Sources, and Prospects

Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, Sulfr hexafluoride will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought sf 6 into the climatic impact discussion aimed at reduction

Sep 01, 2000 · Abstract. Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6 such that the buffer gases efficiently slow down electrons into an energy range where the electron attachment cross section for SF 6 is large.
