ABSTRACT
Farmers in the department of Agboville use pesticides to improve their agricultural yield without knowing their effects on the quality of water resources. The main objective of this study is to assess the level of contamination of surface water and groundwater through the use of pesticides in the department of Agboville. 24 samples of which 18 for surface water and 6 for groundwater were made during the dry season and the rainy season. The laboratory assay made it possible to obtain the concentrations of pesticide active ingredients in the water. Statistical analysis of hydrochemical data and indices of contamination are the different methods used to reach our objective. The order of abundance of the active ingredients detected in the sampled waters is glyphosate> glyphosate isopropylamine salt> deltamethrin> chlorpyrifos-ethyl> thiamethoxam> dichlorodiphenyltrichloroethane. Only glyphosate concentrations in the rainy season have an average greater than 0.1 μg / L while in the dry season it is less than 0.1 μg / L. DDT was not detected in the waters sampled in both seasons. The average values of the ICP (> 2) show that the water is of average quality and according to the average values of the IPA these waters are of good quality (> 0,5 μg / L). Surface water is more exposed to pesticide contamination than groundwater, and contamination is more severe in the rainy season than in the dry season.
Key words: Farmers, Pesticides, Contamination, Water, Agboville.
