Abstract

Dimethoate is an insecticide used to protect different types of crops. In this work, the adsorption of pure and commercial dimethoate in an agricultural soil from Granada (southeastern Spain) were studied using batch experiments. The amount of pure and commercial dimethoate retained was 4.47 and 18.2 μg/g respectively. This result shows the weak adsorption of dimethoate by the soil, which is an indication of water pollution risk, but, the presence of organic additives decreases this risk.
