title: Comparative Evaluation of the Stability of the Brown Forest Soils of Crimea and the Caucasus to Pollution with Heavy Metals
abstract: This article assesses the resistance of brown forest soils of the Republic of Crimea, the Western and Central Caucasus to pollution by lead, chromium, nickel, and copper, and develops regional maximum permissible concentrations of these heavy metals. Soil contamination was modeled under laboratory conditions. Heavy metals were added in the form of oxides. Soil stability assessment was carried out by biological indicators. The brown forest soil of the Republic of Crimea proved to be the most resi
