Reactions in and on sea - salt aerosol particles may have a strong influence on oxidation processes in the marine boundary layer through the production of halogen radicals, and reactions on mineral aerosols may significantly affect the cycles of nitrogen, sulfur, and atmospheric oxidants.
Currently, the role of CH4 oxidation (a microbial process that consumes methane) in mediating atmospheric CH4 fluxes during lake turnover events is also not well understood.
(if 20 % of geologic burial of C (0.2 Gt / year) is organic C and if that is nearly balanced by oxidation of geologic organic C, that would be a C flux of 0.04 Gt / year, which is 0.08 % of 50 Gt / year, so the oxygen depletion, as a fraction of total atmospheric O2, would be 0.08 % * 0.011 % / year = 0.0000088 % / year — or 8.8 E-6 % / year; it would take a bit more than 10 million years to use up all atmospheric O2 by such a process.
