Abstract

The objective of this study is to assess the level of pollution of the river. Nine physicochemical parameters were measured at nine stations between March and October 2016, during periods of flood recession and flooding of the Ouémé River. The methods used are those recommended by the French Association of Normalization (AFNOR).The data were subjected to a univariate descriptive statistical analysis and Principal Component Analysis (PCA). The Leclercq Organic pollution index was used to assess the level of organic pollution. The values of measured parameters indicate a trend to organic pollution on all stations.
