Abstract:

This research was conducted to determine the concentrations of heavy metals and proximate composition of different cereals (maize, millet, and rice). Two different samples each sold in two different markets (Ogbete and Gariki) in Enugu, were used for this work, using atomic, absorption spectrophotometer.
The heavy metal screening of the cereal samples showed the presence of arsenic in the range of 0.456ppm-0.955ppm but was not detected in sample E and f which are the two different rice I purchased from Ogbete market, then mercury in the range of 0.024ppm-0.124ppm, lead in the range of 0.554ppm-1.083ppm, cadmium in the range of 0.087ppm-0.565ppm, copper in the range of 0.050ppm-0.245ppm and zinc in the range of 1.448ppm-66.954ppm which is the highest and is discussed.
The result of proximate composition analysis indicated ash: 1.0%-19.0%, moisture: 8.6%-12.6%, fat: 0.2%-20.0%
