Short summary
Short summary
Lake Toho is a small freshwater lake located in southern Benin. From February to June 2024, water quality was assessed using monitoring equipment. The results indicate high levels of nutrients that could cause ecological problems such as eutrophication and the disappearance of aquatic species. Market gardening and riverside agriculture are responsible for this pollution.
