Microparticles with diameters <1 and 1–10 μm (PM1 and PM1–10) are the most important components of road and city dust and atmospheric aerosols, soils, and other accumulators of toxic substances. The research examines sample preparation techniques and evaluates their influence on the results of the analysis of chemical composition of PM1 and PM1–10. The analyzed samples were taken from the sandy loamy umbric horizon of background southern taiga Glossiс Retisol and the clayey loamy chernic horizon
