QUANTITATIVE ASSESSMENT OF THE CONCENTRATION OF POTASSIUM BROMATE AND SOME SOME HEAVY METALS IN SELECTED BREAD SAMPLES PRODUCED WITHIN KADUNA METROPOLIS, NIGERIA
This study evaluates the concentration of potassium bromate (KBrO₃) and selected heavy metals (Pb, Cd, Cr, Ni) in bread samples obtained from Kaduna Metropolis, Nigeria. Twenty samples were randomly collected from industrial and small-scale bakeries across four local government areas. Potassium bromate was analyzed using UV-Visible spectrophotometry, while heavy metals were determined using Atomic Absorption Spectrometry (AAS). Results showed potassium bromate concentrations ranging from 0.015 to 0.030 mg/kg (mean: …
