 ABSTRACT

Cr, As, Zn, Cd and Pb in the bottom sediments from 11 sites of six bays at Ebrié lagoon in Abidjan area were analyzed. The ranges of the concentration in the sediments are as follows: (mg/kg) : Zn (245.73) > C r (138.34) > Pb (59.33) > As (19.25 > Cd (7.85). Potential contamination of the bays was assessed by Igeo and pollution load index (PLI) whether the concentration observed represent background or contaminated levels. Based on the results, it can be concluded that the bays are highly polluted for the studied metals. To evaluate the sediment quality, the index like a threshold effect concentration (TEC) and a probable effect concentration (PEC) were used. Results show that sediments have toxic effects on organisms, relatively to Cr, Zn, Cd and Pb concentrations, without the concentration of As witch seems to have no toxic effect.
