Abstract
The study was conducted to determine the contamination of seven heavy
metals namely (Mn, Cu, Zn, Pb, Cr, Hg and Fe) in dam water used for
irrigation and fishery in five communities (Atimpoku, Akuse, Small London,
Kpong and Akosombo (control) ) located along downstream of the Volta
Lake and its health impacts on the inhabitants of Manya Krobo District of the
Eastern Region in Ghana. This dam is a major source of drinking water for
Akuse province population. A total of 100 water samples were collected from
five different sites along the dam. The samples were analyzed for heavy
metals using microwave-assisted acid digestion (Milestone ETOS 900) and
Atomic Absorption Spectrometer (Varian AA 240FS). The maximum and
minimum concentrations of Fe, Mn, Cu, Zn, Pb, Cr and Hg in the water were
(0.453 – 0.0.224), (0.012 – 0.002), (0.004 – 0.003), (0.009 - 0.001), (0.101 –
0.053), (0.006 – 0.003) and (0.001) mg/L respectively. There were no
significant differences (p>0.05) in heavy metal concentration between the
various sites and the control. The mean concentrations of Mn, Cu, Zn, Cr and
Hg were found to be within the WHO, Water Pollution Control Legislation
(WPCL), Criterion of Irrigation Water (CIW) and US EPA permissible limits
while Pb and Fe levels recorded were slightly higher
