Hashim et al.
Abstract
The objective of the research was to ascertain the cadmium levels in water, sediments, and the catfish species (Clarias anguillaris) collected at River Benue in Mayo Renawo, Taraba State, Nigeria. The river is exposed to high input of agricultural run-off, waste dumping, bathing, washing, market waste. In this study Cadmium (Cd) was seasonally determined in wet and dry seasons. Analysis of the concentrations of the Cadmium was carried out using spectroscopy. This study revealed that Cd has the lowest value of the concentration in Munci and Mabaka stations with an equal value of (0.02 ± 0.00) in fish during dry season and increase progressively in Mahanga station with ( 0.03 ± 0.01). Cd was not detected in all the whole stations in wet season. In water it indicated that station 1 with 0.09± 0.02 has the highest concentration in both dry and wet and lowest in station 2 in wet with 0.01 ± 0.00 but not detected in station 2 in wet. In sediment it revealed that the concentration was high in dry season with highest in station Munci and Mahanga with equal concentration of 0.04 ± 0.02 but differ in Mahanga station with 0.03 ± 0.01 while wet season has the lowest concentration in station 3 with 0.01 ± 0.003 and with 0.01 ± 0.01 in station 2 while station 1 with 0.02 ± 0.003 with a seasonal variation of 0.04 in dry and 0.02 in wet. The following recommendation is noteworthy: As opposed to being disposed of haphazardly, all solid waste should be recycled.
