Levels of some anions in Sokoto-Rima river system in north in western Nigeria
The level of some anions in Sokoto-Rima River system at the fishing site of the Argungu International Fishing and Cultural Festival (AIFCF) were analyzed. Water samples were collected for twelve months and analyzed for anions. Data generated was analyzed using ANOVA. Statistical analysis of the data was based on the months, wet and dry seasons and five sub-seasons namely early rainy (June and July), flood season (August and September), early dry season (October-December), mid dry Season (January and February) and late dry season (March-May). Chloride, nitrate, phosphorus, sulphate and nitrite ions were within the standard for aquatic life (Vezeau, 1989). Considering the concentrations of above ions obtained in this work, the river water is safe for the aquatic life therein.
Key words: Sokoto-Rima River, anions, water, pollution status, Nigeria, AIFCF
