The role of photocatalysis by transition metal complexes in the environment is reviewed, and its influence on composition of the environmental compartments, transport between them, and activation of the environmental self-cleaning behavior is characterized. In description of atmospheric processes, the attention is paid to coordination compounds as photocatalysts of the transfer and redox reactions of nitrogen oxides. In the case of hydrosphere and soils, various mechanisms of organic pollutant photodegradations are presented in which the iron, copper, and chromium complexes play... 

There continue to be many absorbers for the removal of water-soluble gases. Acid gases and some volatile organic compounds can be absorbed readily in water by the types of equipment previously discussed. These processes are essentially absorption with chemical reaction. For a discussion of absorption in air pollution control and a description of several absorption systems for sulfur dioxide and nitrogen oxide removal, see Schnelle and Brown. A more detailed discussion of many more processes for flue gas desulfurization employing absorption is given by Lunt and Cunic. ... 

The applicability of an additive approach is very doubtful in many other cases too. For instance, a typical task for modeling is a description of the behavior of small additives to the reacting system. Such additives may serve as reaction rate modifiers (promoters or inhibitors). Another important area is a detoxification of pollutants in the conditions of hydrocarbon oxidation (combustion). In both cases the detailed mechanism of the process in the presence of additives (especially, if they contain heteroatoms, such as nitrogen, halogens, sulfur, or phosphorus) can undergo very serious changes, which can hardly be accounted for by the addition of a limited number of new elementary steps.
