Method for evaluating non-economic effects of air pollution

The basic premise underlying the approach presented in the paper is the assumption that humans are unique beings that can evaluate. The environment is described as a system of resources satisfying human needs. The assessment of the effects of environmental pollution derives from the fact that there is, or will be, non-satisfaction of needs resulting from a reduction in environmental resources.     

The Influence of Flame-Generated Free Radicals on the Thermal Oxidation of Waste Gases

Studies of the thermal oxidation of waste gases were carried out in two variants. During the first, the destruction of waste gases was facilitated by hydrogen flame-generated radicals. During the other variant, this flame was not used, but the same temperature was maintained as in the first one. The waste gases used were mixtures of toluene with air and methane with air of 200 and 400 ppm concentrations, respectively. The experiments were performed in a flow reactor within the temperature range of 800 to 1330 K. The efficiency of oxidation of methane and toluene obtained during the first variant was considerably higher than that obtained in the second one. This was due to the promotional effect of the hydrogen flame.
