  ABSTRACT: Many pollutants are likely to compromise the quality of waterways. The Alibori River, located in the cotton basin of Benin, is subject to being compromised by organic pollutants from pesticides used in cotton production. To assess the contamination of the sediments of the Alibori River by pesticides, they were sampled, packaged in aluminum foil, and stored in the laboratory. The presence and content of Cypermethrin, Lambda-cyhalothrin, and Acetamiprid were determined on 5 g of sediment. Extraction was performed using 1% of acidified acetonitrile after purification before chromatographic analysis using an HPLC chromatograph. According to the results, only cypermethrin was detected in the river sediments with concentrations between 2708 µg∙kg−1 and 2732 µg∙kg−1 during the dry season. This appearance of cypermethrin could be explained by its strong adsorption to soil particles and its low mobility. Gas chromatography (GC) is more suited to determining lambdacyhalothrin, which could explain its absence. It would therefore be appropriate to continue analyzing these molecules in surface water and groundwater by adopting several analysis methods.
