More Book Details

Description of the Book:

Aqueous water and sediment samples from six (6) sampling points of lake Chad area were collected and analyzed for sulphates, phosphate and nitrate levels. Determinations were conducted by titrimetry, Brucine and Ammonium molybdo âvandate methods, respectively. The samples were ashed and digested by standard methods before final analysis. Results show variation in concentration of ions with respect to season and location. Higher Sulphate concentration (2620 + 5.65μg/g) was observed in Wulgo (wet season); while highest Phosphate of 1325+8.00) μg/s (dry season); and higher Nitrates of (3151+ 44.75μg/g) was equally observed in Dan Baure in dry season. The variation was statistically significant (P<0.05). Thus, Dan Baure sediments was found to have higher deposition of Phosphate and Nitrate which might be due to high fishing and agricultural activities over long period of time as evident by the high population of fishing and farming in the area
