Assessment of Oued Seybouse Pollution by Anionic Surfactants and their Ecotoxicological Effects on the Freshwater Crusta

This study was conducted to assess both biological and chemical pollution of Oued Seybouse (Guelma). To achieve that, indicator bacteria of faecal pollution were isolated and counted and physico-chemical parameters of such watershed including anionic surfactants were measured. Also, acute toxicity of sodium dodecyl sulphate (as an ionic surfactant) was tested on Daphnia magna.
