Forest fires environmental impact study

Abstract

Abstract The impact of the toxic components of the pyrolysis products of forest combustible materials, air temperature, and thermal radiation on the environment was studied. The data on the amount of solid particles contained in the smoke of forest fires and controlled fires are presented. The ratio of the mass of solid particles of smoke aerosol and the mass of burnt combustible material for different combustible materials is determined. The data on the toxicity of gases generated during the forest combustible materials burning and their effect on the human body are presented. The specific emissions (emission factors) of substances in a fire are determined and the methodology for their calculation is given. The dynamics of forest burnability in the Krasnoyarsk Territory over the past 48 years and the reasons for the increase in forest area covered by fires are presented. Measures to reduce harmful emissions from forest fires into the atmosphere and to reduce environmental pollution by improving the mechanisms for regulating forest protection activities and preventing the occurrence and extinguishing of forest fires are proposed.
