Determination of Organic Pollution Indicators in Lukaya River, Kinshasa, Democratic Republic of Congo.
This study was conducted under the ecological conditions of Kinshasa. It analyzes the waters of Lukaya river and its tributaries in the section crossing the town of Kinshasa; from the point of water catchment by the Régideso station upstream of the tributary Bumuna. The physico-chemical and chemical analysis were done in order to measure the concentrations of parameters indicators of organic pollution in Lukaya River and its tributaries in order to calculate the organic pollution index and evaluate the contribution of pollutants to the tributaries. The results revealed that the waters of the Lukaya River and its tributaries are weakly mineralized. The electrical conductivity of waters varies with the inflow of tributaries. Minocongo's poultry activities tend to increase the pH and nitrate concentrations of waters. Organic pollution index indicates zero pollution of the River’s waters and its tributaries.
