Abstract

Seasonal variation in heavy metal distribution of major dams in Ekiti State was carried out. Of all the metal examined, iron was found to be the most abundant metal for both seasons for the two years with an average value of 6.48 and 4.80m/100g (2001) and 6.51 and 3.62 mg/100g (2002) for dry and wet season respectively, the average metal concentration increased yearly. The concentration of most of the metals appears higher in the dry season than those recorded for the wet season. The values of the metals are below the standard limits of world health organization.
