Soil Pollution by Household Waste and Its Consequences
Year: 2025
Type: article
Abstract: The article provides information on soil pollution, which has become a global problem worldwide today. Contamination of soils around household waste dumps with heavy metals (such as lead, bismuth, nickel, and cadmium) significantly affects the activity of soil microorganisms. These effects have negative consequences for the composition of microorganisms, their biochemical processes, and the overall health of the soil. As a result of burning household waste, Cd and Pb accumulate in the soil, and their concentrations increase over the years. Analysis of soil samples taken from the southern, eastern, northern, and western parts of the study area showed that the amount of heavy metals in the eastern and western parts of the study area is higher than in the southern and northern parts. In the studies, the content of cadmium (Cd) in soil samples MCHJ -1.1 and MCHSha- 1,1, MCHShi-1, MCHG‘-1 changed in the amount of 0.11, 0.46, 0.08, 0.06 mg/kg, and it was found that the content of this substance exceeded the clarke (0.13) only from the point MCHSha- 1,1. Cd increased significantly only in the MCHSHa-1.1 zone. It was established that the content of lead (Pb) at all points exceeds the Clarke value (16) by 2-3.5 times. MCHG-1 and MCHSHa-1.1 increased by 3.5 times, MCHJ-1.1 and MCHSHi-1 - by 2 times, and these indicators are close to the background soil indicators.
