Trace Heavy 'Metals In Fish And Sediments Or Some Rivers Around Industrial Areas Of The Kaduna River Basin

ABSTRACT

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 flam e atomic

absorption spectrophotometry. The HN03 - I-1202 digestion.... s ystem was used

to digest the fish sample far trace m etals det ermination. 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 .iO. l and

Zn = 1. 5 .i0.9. 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. Thl!rl!l()re all the

metals determined exhibited no discemable- elevation in concentration.
