The level of Cd, Co, Cu, Mn, Ni, Pb and Zn in fish and sediments of Rivers within the Kaduna South Jndustrial Zone were determined by flame atomic absorption spectrophotometry. The HN03 - I-1202 digestion .. .. system was used to digest the fish sample far trace m etals determination. Tire HN03 - H202 digestion method gave good recoveries which vCiries within 80-95% for Cd, 85-97% for Co, 81-99% for Cu, 79-97% for Mn, 81-93% for Ni, 87- 98% for Pb Clnd 77 - 98% for Zn in a fish smnple. The Clverage concentration of m etals in the fish samples were Cd = 0.3 + 0.1 , Co = 0.48±0.0 1, Cu = 3.9+0. 3, Mn = 6. 5 ±0.1, Ni = 4.9+0.1, Pb = 0.3 .i_O. l and Zn = 1. 5 .i_0.9. The order of these concentrations in the fish is Mn>Ni> Cu> Zn> Co> Pb> Cd. The mean meLt! levels in the sediment sample collected from the same locations were Cd = 1.5 +0.1 , Co = 6.6+ 0.3, Cu = 9. 5 + 1.4. M11 = 32.0 + I O.l, Ni = 10.0 + 1.4, Pb = 18.4 +9.1 and Zn = 12.5 +4.3. The concentration order in the scuiment su1nple is Mn > Pb > Zn > Ni > Cu > Co > Cd. 1. comparison or tltc metal levels iu this stuuy area to other region of Africa und the world shows that the levels in this study area are low compunxi to the level or Jllclals rronl other study :trl!llS.
