A Mini Review on Long-Term Contamination of Tropical Volcanic Soils

Abstract

Jianzhou Yang

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.
