Caractérisation bactériologique des eaux résiduaires brutes de la ville de Cotonou (Bénin)

Abstract: RESUME Objectif : La présente étude vise à évaluer la pollution fécale des eaux usées de Cotonou, ville la plus peuplée du Bénin. Méthodologie et Résultats : Trois stations correspondant au point de rejet de trois collecteurs ont été échantillonnées durant une période de 11 mois allant de Janvier à Novembre 2013. La température, le pH, la conductivité électrique et la teneur en oxygène dissous ont été mesurés in situ. Le dénombrement des bactéries indicatrices de contamination fécale a été réalisé par la métho… Show more

“…It should be noted that the loads of these indicators are higher than the values set (10 3 CFU/ 100 ml) by WHO guidelines for the safe discharge of wastewater into the environment [16]. A similar finding has been made by other authors in Africa by (Aboulouafa; El Addouli; Adjahouinou; El Ouali; Coulibaly) [15,17,18,19,20].…”

“…Due to urban development and strong population growth in the study region, the Nokoué Lagoon faces substantial anthropogenic pressure (Dovonou et al, 2011;Zandagba et al 2016), evident in elevated levels of pollutants including heavy metals, pesticides and fecal bacteria (Lalèyè et al, 1997;Ogutu -Ohwayo et al 1997;Aina et al, 2012a;2012b;Adjahouinou et al, 2012Adjahouinou et al, , 2014Yehouenou, 2013). The fate of these pollutants, which are notably associated with wastewater discharge or rainwater runoff from the shores, remains a major concern, given that their concentrations are prone to being elevated in specific locations.…”
