Abstract: This study aimed to compare the efficiency of C18 and Activated Charcoal (AC) for extracting pesticide residues (glyphosate, butachlor, lambda-cyhalothrin, and paraquat dichloride) from river Mada in Nigeria during the rainy and dry seasons. Solid phase columns were packed with 0.1 g of each adsorbent material, and water samples were taken from five different points along the river during each season. Pesticide residues were extracted using the two adsorbents, and elution was done using n-hexane, acetonitrile, and acetone. The eluents were analyzed using UV-visible spectrometry. Glyphosate levels were found to be significantly higher (at P
