Abstract This article presents the results of long-term observations of the formation of atmospheric pollution by fine particles in burnt forest areas and in the surrounding areas. By studying snow cover, it was established that during the observation period of 4 years, carbon and mineral particles are formed in burnt forest areas, and are transferred by wind to the surrounding territory. Research via an electron microscope has established that microparticles formed in the burnt areas can consist of either individual grains or an association of small particles formed during the condensation-coagulation of organic substances at the time of the fire. The chemical composition of the particles contains carbon, aluminum, silicon, iron, zinc and other chemical elements. The results of the analysis of the chemical composition of the particles are processed by factor analysis using the principal component method. Possible mechanisms for the formation of particles and the formation of their chemical composition are considered.

西外贝加尔（俄罗斯）烧毁林区积雪中分散颗粒的形态和化学成分

摘要 本文介绍了对燃烧林区及其周边地区细颗粒物形成大气污染的长期观测结果。通过研究积雪，确定在 4 年的观测期内，碳和矿物颗粒在被烧毁的森林地区形成，并被风转移到周围地区。通过电子显微镜的研究已经确定，在燃烧区域形成的微粒可以由单个颗粒或在着火时有机物质凝结凝结过程中形成的小颗粒组成。颗粒的化学成分含有碳、铝、硅、铁、锌等化学元素。颗粒化学成分的分析结果采用主成分法进行因子分析处理。考虑了粒子形成的可能机制及其化学成分的形成。
