Determination of Selected Heavy Metals In Seasonal River In Maru Town, Zamfara State, Nigeria.

Abstract

The presence of heavy metals in our environment has been of great concern because of their toxicity when their concentration is more than the permissible level. The main threats to human health from heavy metals are associated with exposure to Lead and Cadmium. These metals have been extensively studied and their effect on human health regularly monitored and reviewed by international bodies such as the WHO and USEPA. Total levels of Cd, Pb, Cu, Zn and Cr were determined in seasonal river in the eastern part of Maru using Flame Atomic Absorption Spectrophotometer (FAAS). The results of total metals concentration (ppm) in the river were 0.0211±0.0014, 0.177±0.0004, 0.0201±0.0031, 1.1367±0.0493 and 0.0058±0.0003 for Cd, Pb, Cu, Zn and Cr respectively. The study showed that the sample was contaminated with Zn when compared to others. The level of Cd and Pb were high when compared to their safety limit (0.01 and 0.10) by U.S.E.P.A.
