Abstract:

 Pollution by trace metals (TME) is a current problem that concerns the scientific community concerned with maintaining the environment at a level of quality conducive to human health and well-being. The objective of this study is to evaluate the level of contamination of the sediments of Taabo Lake by cadmium, mercury, lead and chromium. To do this, 15 sediment samples were collected in three (3) sampling campaigns, from five (5) stations. Analyses by the Varian flame atomic absorption spectrometric (AAS) method for chromium, lead and cadmium and, the cold vapor atomic absorption spectrometric (CV-AAS) method for mercury focused on the fine fractions of the sediments (φ < 63 μm). Geoaccumulation index (Igeo) and Contamination factor (FC) were determined for establishing the level of contamination of sediments by metallic trace.The results show that the concentrations of cadmium (2.494 ppm), mercury (0.685 ppm) and lead (17.850 ppm) in the sediments of Taabo Lake are higher than in the earth's crust. Chromium, on the other hand, at 6.980 ppm, is lower than the earth's crust. The geoaccumulation index (Igeo) and the contamination factor (CF) revealed sediments highly contaminated by cadmium and mercury. Lead contamination of sediments is said to be moderate. However, low or no chromium contamination of sediments was found. [.
