Physico-Chemical Assessment of the Water Quality of the Yopougon Bay, (Lagune Ebrie, Cote D'ivoire)

Abstract

The study focuses on the analysis of the physicochemical parameters of the bay of Yopougon. A first series of data was measured in situ at a fixed station in the bay where a sensor was installed. Another comes from an analysis of the water sample. This work was carried out as part of the monitoring of RNO water (national observation network). Its objective is to evaluate the characteristics of the physico-chemical chemical parameters (pH, temperature, conductivity, TDS, dissolved oxygen, ORP, TSS) of the Yopougon bay and of the nutrient salts (ammonium, nitrite and phosphate). The study was conducted on the surface and in the bay's water column. The curves obtained show a variation in the physico-chemical parameters from the surface to the depth of the bay. The concentrations of the parameters are above normal. The waters of Yopougon Bay are warm, alkaline. They are impacted by discharges from agro-industrial companies and wastewater. This water could be very harmful to use and therefore unsuitable for human consumption.
