The impact of industrial enterprises on soil enzymes (on the example of Tashkent region)

This article analyzes ecological changes in the activity of enzymes in the soil under the influence of some large industrial enterprises operating in the Tashkent region. It was also studied that the activity of enzymes in the soil composition was more affected in soils around the Angren Thermal Power Plant, the New Angren Thermal Power Plant, and the Almalyk Mining and Metallurgical Complex than in other study areas. Irrigated dark gray soils distributed around the Angren TPP, New Angren TPP and Angren oil base, as well as typical irrigated gray soils distributed around the Almalyk Mining and Metallurgical Combine JSC and Ammophos-Maxam JSC were tested and analyzed in laboratory conditions. According to the results obtained, it was believed that industrial waste negatively affects the activity of enzymes in the soil.
