Chlorine cycle

[3] Chlorine plays a large role in atmospheric cycling and climate, including, but not limited to chlorofluorocarbons (CFCs).

[2] Biomass combustion is another source of both organic and inorganic forms of chlorine to the troposphere from the terrestrial reservoir.

[3] The majority of chlorine fluxes are within the hydrosphere due to chloride ions' solubility and reactivity within water systems.

[2] Organically bound chlorine is as abundant as chloride ions in terrestrial soil systems, or the pedosphere.

[7] These highly reactive chlorine ions will also interact with volatile organic compounds to form other ozone depleting acids.

[3] Its half-life of 3.01×105 years, mobility in the pedosphere, and ability to be taken up by organisms has made it an isotope of high concern among researchers.

Biogeochemical chlorine cycle: chlorine is cycled through the atmosphere, mantle, crust, pedosphere, cryosphere, and oceans as chloride and organic chlorine. [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] Arrows are labeled in fluxes of chlorine in Tg (teragram) per year. Estimates are also made of natural chlorine contents in Earth's reservoirs and the form they are stored in. [ 1 ] [ 2 ] [ 3 ] The mantle constitutes the largest reservoir of chlorine at 22 x 10 12 teragrams. [ 2 ] Chlorine is cycled through the pedosphere via biotic and abiotic processes that lead to this reservoir acting as a sink. [ 1 ] [ 3 ] [ 4 ] [ 5 ]
