The concentrations of toxic metals in many ecosystems are reaching unprecedented levels. The aim of this research work was to assess heavy metals concentration in River Kaduna water in relation to seasonal variations. Twenty-four water samples were collected for the period of eight months between January and September, 2023 and were used to assessed the concentration of selected heavy metals in water samples. Samples were assessed using Atomic Absorption Spectrometer (AAS). The mean concentration of heavy metals in wet season water sample downstream are: Pb 0.0520 ± 0.0179ppm, Cd 0.0613 ± 0.0167ppm, Cr 0.8907 ± 0.1030ppm, Cu 0.7108 ± 0.2300ppm and Zn 1.5202± 0.2600ppm. The Dry season include; Pb with 0.0524 ±
0.0217ppm, Cd, 0.0703 ± 0.0042ppm, Cr, 0.9319 ± 0.1780ppm, Cu, 0.7271 ± 0.2675ppm and Zn, 17.1686 ±4.9498ppm. The result obtained shows that there was significant difference (P<0.05) between the mean concentration of heavy metals in wet and dry season at 5% level of significance only with Pb and Zn whilst Cd, Cr and Cu were not statistically significant. While the mean concentration of heavy metals in wet season water sampled midstream were; Pb 0.0500 ± 0.0186ppm, Cd 0.0490 ± 0.0186ppm, Cr 0.8367 ± 0.1630ppm, Cu 0.7287 ± 0.3203ppm and Zn
1.9674± 0.6148ppm. Dry season are: Pb 0.0524 ± 0.0217ppm, Cd 0.0515 ± 0.0142ppm, Cr 0.9667 ± 0.1420ppm, Cu 0.8270 ± 0.2675ppm and Zn 2.0723 ± 0.4310ppm. the result obtained shows that there was significant difference(P<0.05) between the mean concentration of heavy metals in wet and dry seasons.
