"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.

Soils, waterways, aquatic life, and crops all became permanently poisoned as a result. WISORCH, a leaching model based on first-order desorption kinetics, was developed and tested to determine the degree and duration of soil pollution. The SOC/water partitioning coefficient and the organic carbon content of the soil are the input parameters (Koc). It takes into account the current concentrations of chlordecone and drainage water in the soil. The fact that the model worked for andosol indicates that there was no physicochemical or microbiological degradation. Dilution from previous deep tillages renders soil scraping impractical. Liviation appeared to be the most important strategy for reducing pollution. Koc changed from nitisol to ferralsol and then increased once more in tandem with an increase in SOC content and rainfall.
