Evaluation of Pesticide Contamination Levels in Pineapple Plantations Soils in Three Areas of the Sud-comoé Region (Côte D'Ivoire)

This study was conducted in Côte d'Ivoire, specifically in the Sud-Comoé region, encompassing the Assé, Toumanguié, and Samo zones. The aim was to identify and quantify pesticide residues in the soils of pineapple plantations in these areas. The study involved 60 soil samples, carefully collected at a rate of 20 samples per site. The samples were prepared and analysed using a SHIMADZU high-performance liquid chromatograph system. The analysis revealed the presence of pesticide residues, including glyphosate, aldicarb, profenofos, parathion-methyl, cypermethrin, permethrin, deltamethrin, chlorpropham, and lambda-cyhalothrin, in concentrations ranging from 0.022 to 0.088 mg/kg. The pesticide residues found belong to two major families of pesticides, namely insecticides and herbicides. Except for aldicarb and lambda-cyhalothrin, all detected residue levels were below the safety thresholds set by the Codex Alimentarius. This indicates that soils in these plantations could be capable of supporting the production of pineapples that meet quality standards for human consumption.
