In order to protect and improve market garden crops, market gardeners use large quantities of plant protection products and water in the production area. This has an impact on soil quality. The aim of this study was to determine the level of soil pollution downstream of the Daloa Regional Hospital. Twenty-four soil samples were taken from six sites in the study area. These samples were analysed by liquid/liquid chromatography coupled with mass spectrophotometry. The results of the analyses revealed the presence of seven medicinal residues, including five antibiotics (Ciprofloxacin, Erythromycin, Tetracycline, Sulfamethoxazole and Norfloxacin), a beta-blocker (Propranolol) and an anti-inflammatory (Salicylic Acid). The average concentrations of these antibiotic residues ranged from 3.41 to 50.34 µg/kg; the anti-inflammatory and the beta-blocker recorded values of 112.67 µg/kg and 17.35 µg/kg respectively. Eleven residues of active ingredients, including Chlorothalonil, Cypermethrin, Metamidophos, Endrin, Deltamethrin, Dimethomorph, Profenofos, Beta-endosulfan, Etoenprox, Furathiocarb and Carbendazim, were quantified at levels ranging from 0.04 to 39.62 µg/kg. These active ingredients belong to five families of plant protection products: organochlorines, organophosphates, carbamates, thiocarbamates and synthetic pyrethroids. The constant discharge of these medicinal and phytosanitary residues contaminates the soil and poses a threat to humans and their environment.

The aim of this study was to determine the level of soil pollution downstream of the Daloa Regional Hospital. Twenty-four soil samples were taken from six sites in the study area. These samples were analysed by liquid/liquid chromatography coupled with mass spectrophotometry.

Abstract: (french)
Soucieux de protéger et d’améliorer les cultures maraichères, les maraichers utilisent une importante quantité de produits phytosanitaires et des eaux dans la zone de production. Cela influence la qualité des sols. L’objectif de cette étude est de déterminer le niveau de pollution du sol situé en aval du CHR de Daloa. Ainsi, Vingt - quatre échantillons de sol ont été prélevés sur six sites de la zone d’étude. Ces échantillons ont été analysés par chromatographie Liquide / Liquide couplée à une spectrophotométrie de masse. Les résultats des analyses ont révélé d’une part, la présence de sept résidus médicamenteux dont cinq antibiotiques (la Ciprofloxacine, l’Erythromycine, la Tétracycline, la Sulfaméthoxazole et la Norfloxacine), un Bétabloquant (le Propranolol) et un anti-inflammatoire (Acide Salicylique). Les concentrations moyennes de ces résidus d’antibiotiques ont varié de 3,41 à 50,34 µg / Kg; l’anti-inflammatoire et le bétabloquant ont enregistré les valeurs respectives 112,67 µg / Kg et 17,35 µg / Kg. D’autre part, onze résidus de matières actives notamment le Chlorothalonil, la Cyperméthrine, le Métamidophos, l’Endrine, le Deltaméthrine, le Dimethomorphe, le Profenofos, le Béta-endosulfan, l’Etoenprox, le Furathiocarbe et le Carbendazime ont été quantifiés à des teneurs allant de 0,04 à 39,62 µg / Kg. Ces matières actives appartiennent à cinq familles de produits phytosanitaires à savoir les organochlorés, les organophosphorés, les carbamates, les Thiocarbamates et les pyréthrinoïdes de synthèse. Le rejet en permanence de ces résidus médicamenteux et phytosanitaires contamine le sol et constitue une menace pour l’homme et son environnement.
