Abstract:The present study aimed to assess the physico-chemical quality of wastewater(s) in order to better control the flow of various pollutants generated by the industries from the industrial zone of Cotonou. Water samples were collected in triplicate in each collector and analyzed for their nutrient and metal content (Cu2+, Fe2+, Cd2+, Al3+ and Pb2+) and chemical oxygen demand (COD) and a five-day biochemical oxygen demand (BOD5) were carried out by spectrophotometry. The results revealed highly mineralized waters,… Show more
