Abstract

The study was conducted from May 2022 to March 2023 on the Comoe and Iringou rivers in Comoe National Park. Its aim was to assess the physico-chemical parameters and ecological stress levels of these rivers. The results show that both rivers have fewer ecological pollution parameters, with average pH values close to neutral (6.8 to 7.3). The average dissolved oxygen recorded in these streams over the two seasons indicates a level of oxygenation favorable to aquatic life. The assessment of the level of ecological pollution reveals moderate pollution at the sites studied, with the exception of Kafolo and the Ecological Research Center. Principal component analysis shows two categories of stations on the Comoe River: Kafolo station is characterized by high electrical conductivity and total dissolved solids, and the Ecological Research Center and Ganse stations by high pH and temperature. On the other hand, the stations on the Comoe River contrast with those on the Iringou River, with higher values for physico-chemical parameters.

 

Key words: Comoe National Park, Comoe and Iringou rivers, physico-chemical parameter, spatio-temporal, ecological pollution.
