Influence of forest fire smoke on the decline of biodiversity and the state of living organisms (literary review)

Abstract

Introduction. The relevance of this work is due to the growing environmental problem associated with large-scale forest fires and insufficient knowledge of the survival, adaptation and reproduction of animals after prolonged exposure to harmful smoke components. The aim of the review is to collect and analyze information on environmental pollution due to smoke from forest fires and their impact on animals in the smoke zone. Material and methods. The material for the analysis was the literature sources published for the period up to 2022, in publications indexed in the Scopus, Web of Science, Publons, Springer, PubMed databases, including domestic and foreign research scientists on this topic. Results. When forest fires occur, a mixture of gaseous compounds is released into the environment, containing ultrafine solid particles, carbon monoxide, ozone, polycyclic aromatic hydrocarbons, nitrogen and sulfur dioxide, aldehydes, chlorinated dioxins, free radicals and many other compounds. At the same time, significant damage is caused to a wide biodiversity of the animal world, which is an extremely important indicator link in almost any biocenosis. Conclusions. The increase in large-scale smoke is increasingly leading to the risk of extinction of wildlife exposed to high concentrations of toxic components of smoke. It is necessary to constantly maintain and restore the biotic potential of populations of endangered species in forest ecosystems, as well as a deeper study of the mechanisms of the occurrence of consequences that are dangerous for the animal organism when exposed to forest fire smoke.
