A Review on Techniques for Soil Pollution Reduction

Abstract

Xi Liu

"Soil pollution" refers to a chemical or substance that is out of place, is present in greater quantities than normal in the soil, and harms any organism that is not the target. Because it is frequently difficult to measure or see, soil pollution is a hidden threat. According to the Status of the World's Soil Resources Report (SWSR), soil pollution is one of the most significant issues affecting the world's soils and the ecosystem services they provide. Concerns about soil pollution are growing in every location. The United Nations Environmental Assembly (UNEA-3) recently issued a resolution that called for quicker action and increased cooperation to address and control soil pollution. The global significance of this issue is demonstrated by this agreement, which was reached by more than 170 nations. The majority of anthropogenic sources of soil pollution are chemicals used in or made in industrial processes, household, animal, and municipal wastes (including wastewater), agrochemicals, and petroleum-derived products. The application of sewage sludge on land, irrigation with untreated wastewater, and the use of fertilizers and pesticides are all examples of intentional releases of these chemicals into the environment. Leaching from landfills and oil spills are examples of accidental releases. Smelting, transportation, pesticide spray drift, radionuclide deposition from air weapons testing, nuclear accidents, and incomplete combustion of various compounds all contribute to soil pollution.
