The results showed that there was a significant amount of hexavalent chromium, which determined the plant at 9.2 mg / kg and the soil at 35 mg / kg, classified as hazardous, which has a negative impact on the environment. in place and on the one hand. Another major pollution phenomenon is the pollution of groundwater by this pollutant. The main source of this contamination is the effluent discharged by the tannery of the valley, which contributes negatively to the high degree of pollution without an effective mechanism to reduce this pollution. Dieses Problem erfordert ein sofortiges Eingreifen der Behörden zur Reduzierung des Gerbereiabfalls, um die Umwelt des Oued Mellah zu schützen.
