Abstract


The bay of M’Badon is the receptacle of wastewater of various origins, leaching water from plantations and leachate from the Akouédo landfill. All these inputs are likely to pollute this aquatic environment, which is used by the population for fishing and market gardening. The objective of this study is to determine the quality of the water and surface sediments in the bay. To achieve this, a sampling campaign allowed the collection of a total of sixty-six samples, twelve of leachate, twenty-seven of bay water and twenty-seven of surface sediments. Parameters such as COD, BOD5, NO3-, NO2-, NH4+, SO4-, PO43-, Na+, K+ and Ca2+ were measured by the methods of the French Agency of Standardization and trace metal elements (Zn, Cu, Ni, Cr) were measured by atomic absorption spectrometry. The average values of COD (1306.25 mg O2L-1), BOD5 (575.85 mgO2L-1), NO3- (92.92 mgL-1) and PO43- (128.74 mgL-1) of the Akouédo landfill leachates are well above Ivorian standards. The waters of the bay are turbid, with an average TSS concentration of 65.13 mgL-1. They have a high load of organic and mineral oxidizable matter, with average COD and BOD5 values of 160.70 mgO2L-1 and 64.04 mgO2L-1 respectively. Their mineralization is due to the combination of two processes, one natural and the other anthropogenic. The average NH4+ concentration (0.22 mgL-1) is higher than the French guide value. The sediments of stations B1, B4 and B5 are polluted by Zn and Cu, and the sediments of all stations are polluted by Mo. M'Badon Bay is polluted by anthropogenic activities.
