Comparative analysis of some heavy metals in local and parboiled rice in Bauchi state, North Eastern, Nigeria

Abstract

Comparative determination of some heavy metals (Cu, Zn, Cr, Pb & Mn) in local and parboiled rice, the present study aim at determining the comparison between some heavy metals in local and parboiled rice obtained from five samples at rice. the level of selected metals (Cu, Zn, Cr, Pb & Mn) were determined by atomic absorption spectrophotometry in the rice sample collected from various market located within Bauchi metropolis. The geometric mean concentration of Cu, Zn, Cr, Pb & Mn in rice sample were 0.302mg/l, 0.326mg/l, 0.074mg/lm, 0.214mg/l & 0.044 respectively, Cu & Zn content in parboiled rice were much higher than local rice sample examined in this work.
