The search for higher and higher agricultural yields leads to the use of chemical fertilizers and phytosanitary products. The abusive or repeated use of these agricultural inputs results in soil, surface water and groundwater pollution. With the development of this new form of agriculture, the input of heavy metals to the soil has increased. Research on the fate of these pollutants in the environment is important. It is within this framework that this study was undertaken to evaluate the level of pollution due to trace metals in soils in the cotton growing zone in southern Togo. Soil samples were taken in cotton fields during the dry season. The first analyses led to the determination of some physico-chemical characteristics of the soils including pH, granulometry as well as the cation exchange capacity (CEC). These first two parameters revealed that the soil was slightly acidic and essentially clayey in texture. Then, after mineralization of the soils, the solutions obtained were analyzed with an atomic absorption spectrophotometer (AAS). Twelve (12) metals (V, Cd, Hg, Na, Cr, Ni, Sn, Pb, As, Zn, Cu, Fe) were studied. The concentration of metal ions varies from 0.0038 mg/kg (for vanadium to 5647.31 mg/kg (for iron). The order of abundance for the elements is as follows: V< Ni < Cr < Cd < Na < Hg < Sn < As < Pb < Cu < Zn < Fe. The values found during the analyses compared to the French standards (0.7mg/kg for Cd and 60 mg/kg for Pb) shows that no investigation threshold is reached.
