«For example, in the future methane levels could increase as a result of increased natural gas and energy use, climate change feedbacks and / or a decrease in the global abundance of the hydroxyl radical, which chemically removes methane from the atmosphere.»
«All three of these molecules are removed by the same process — reaction with hydroxyl,» a radical formed from water in the atmosphere, explains Nobel Prize - winning chemist F. Sherwood Rowland, who participated in the research.
The two most common ways of creating what is a false alkalinity are use of bicarbonates or drinking water from machines that make alkaline water by chemically splitting water into a retained hydroxyl radical that is alkaline and an acid proton that is flushed away.
In the case of alkaline water, hydroxyl radicals are so caustic that the body has multiple mechanisms for preventing such molecules from getting to the cells or systems of the body.
But when you have excessive iron, it catalyzes the formation of excessive hydroxyl free radicals from the peroxide, which decimate your mitochondrial DNA, mitochondrial electron transport proteins and cellular membranes.
These free radicals (such as: superoxide, hydroxyl radical, and peroxynitrite) are controlled by antioxidant systems and when these systems can't cope with the amount of free radicals produced these free radicals scavenge for electrons from proteins, cell membranes, and DNA.

This differs from gases like methane which do have a «real» lifetime due to reactions with hydroxyl radicals, where for any given steady state anthropogenic methane emissions are, a stabilized concentration value will eventually be reached.
Third, although many of the individual steps have been established experimentally (18), surprisingly, the mechanism of production of MSA from OSC gas phase oxidation by hydroxyl radicals (OH, daytime) and nitrate radicals (nighttime) remains unclear (31).
In the Supplementary Report (IPCC, 1992) to the FAR, the indirect chemical effects of CO, NOx and VOC were reaffirmed, and the feedback effect of CH4 on the tropospheric hydroxyl radical (OH) was noted, but the indirect RF values from the FAR were retracted and denoted in a table with «+», «0» or «--».
