Levels of Some Cations in Sokoto: Rima River System in North Western Nigeria

Abstract

The levels of some cations in Sokoto- Rima River system at the fishing site for Argungu International Fishing and Cultural Festival (AIFCF) were analyzed. Water samples were collected for twelve months and analyzed for cations. Statistical analysis was based on months, wet and dry seasons and five sub-seasons (early rainy, flood, early dry, mid dry and late dry seasons). NH₄ and Fe ions concentrations were higher than the recommended water quality standards while Na, Ca, Mg and K ions were within recommended standards for aquatic life. The water of this river is therefore safe as far as Na, Ca, Mg and K ions are concern, however, unsafe with regard to NH₄ and Fe ions.
