The contribution of natural halogenation processes to the atmospheric halomethane burdenstimulated a burgeoning interest in identifying and quantifying the natural sources of volatile halogenated compounds. In terms of atmospheric abundance the most important of these compounds are undoubtedly the gaseous monohalomethanes, in particular chloromethane (CH.Cl).

Detoxification of chlorophenols in soils by oxidative transformations on manganese and iron oxidesgated. Mn oxides are very powerful in causing the oxidation of chlorophenols, whereas the effect of the Fe(III) oxide was relatively limited under the conditions studied. Overall, 2,4,6-TCP was the chlorophenol most susceptible to the oxidation and 2,3,5-TCP the least.
