Environmental Impact Assessment of Technogenesis on Genetic Features, Composition and Properties of Light Gray Forest Soils

Abstract

Abstract The paper presents an environmental impact assessment of technogenesis (waste slag from metallurgical production) on the genetic characteristics of light gray forest soils. To study the degree of technogenic impact of the slag dump on the degradation changes in the morphological characteristics and composition of light gray forest soils in the area of action of the slag dump of fines of aluminum casting on the example of a slag dump in the village of Bolshoye Dumchino, Mtsensk district of the Oryol region, field and laboratory studies of soil samples taken at different distances from the slag dump - 20 m, 150 m, 300 m, 450 m. The soil cover of the territory in the area of the slag dump is represented by light gray forest soils, which are characterized by the following typical diagnostic horizons with characteristic morphological features at different distances from the dump. This research aims to establish the degree of anthropogenic transformation of light gray forest soils of agricultural areas, disturbed by the technogenic impact of metallurgical waste. The tasks were solved, as a result of which the influence of the slag dump on the typical diagnostic features of the genetic horizons of light gray forest soils was established. The nature of the change in the aggregate and granulometric composition in the profile of light gray forest soils in the area of influence of the slag dump was studied. An assessment of the degree of degradation changes in the physicochemical properties of light gray forest soils at different distances from the pollution source is given.
