HEAVY METAL CONCENTRATION IN SEDIMENTS, PRAWN AND FISH FROM THE ISAKA RIVER | Journal of Global....

The heavy metal concentrations in sediments, prawns, and fish (SP&F) from the Isaka River were determined in this study. Bundu, Ibeto, Macoba, and Union-Dicon were the four river stations where samples were taken. Vanadium, Chromium, Nickel, Copper, Barium, Cadmium, Arsenic, Mercury, and Lead were measured using an atomic absorption spectrophotometer. The following are the outcomes: In Bundu, SP&F, and Ibeto, Vanadium concentrations were 0.640.02, 1.440.02, and 3.942.16 mg/kg, respectively; in Ibeto, concentrations were 0.710.01, 4.793.19, and 8.061.28 mg/kg, respectively. For SP&F, Macoba showed concentrations of 0.850.02, 1.820.06, and 6.971.53 mg/kg, whereas Union-Dicon had values of 0.680.13, 1.660.02, and 7.061.19. Bundu's chromium concentrations in the SP&F were 3.110.00, 3.010.66, and 119.7420.20 mg/kg, whereas Ibeto's were 2.370.38, 3.540.75 mg/kg. 160.707.46 mg/kg and 160.707.46 mg/kg, respectively. Macoba had concentrations of 4.190.04, 4.960.59, and 143.604.72 mg/kg in SP&F, whereas Union-Dicon had concentrations of 3.850.03, 7.111.99, and 162.0613.09 mg/kg. Nickel concentrations in Bundu SP&F were 1.710.11, 5.62.36 and 29.7013.14 mg/kg, respectively, whereas Ibeto were 1.540.02, 4.620.47, and 55.7623.36 mg/kg. SP&F values in Macoba and Union-Dicon were 2.140.03, 6.721.22, and 57.484.72 mg/kg, respectively, and 1.580.04, 7.212.24, and 44.504.51 mg/kg. Copper concentrations in SP&F in Bundu, Ibeto, Macoba, and Union-Dicon were 3.200.06, 4.290.07, and 178.013.74, 4.2410.39, 7.341.50, and 230.9497.6, 4.541.23, 8.590.77, and 196.952.13 mg/kg, respectively. Bundu had concentrations of 1.510.27, 3.580.30, and 70.267.21 mg/kg in SP&F, Ibeto had values of 1.980.15, 3.340.18, and 69.912.30 mg/kg, and Macoba had concentrations of 2.490.31, 4.040.91, and SP&F concentrations were 2.790.11, 4.980.45, and 63.8713.60 mg/kg in Union-Dicon and Union-Dicon, respectively. Cadmium, arsenic, mercury, and lead were all found to be below the detection limit. The river is contaminated with heavy metals, according to the study, making the marine seafood obtained from it dangerous for human consumption.
