dc.description.abstract The presence high levels of potassium bromate in bread is very undesirable considering its deleterious effects and heavy metals also are implicated in carcinogenesis, mutagenesis and teratogens . In our study standard curve of potassium bromate and heavy metals ( nickel , iron and copper ) the strategy showed good linearity regression (R2 = 0.99 ). linearity of the strategy was performed during a range 1- 5 ppm of KBO3 and therefore the method showed good linearity regression (R2 = 0.97) with y=0.157x , 10 – 50 ppm of Cu (R2 = 0.99 ), with y = 0.001 x , 1- 5 ppm of Ni, with y = 0.018 x and (R2 = 0.99 ) , 1-5 ppm of Fe with y= 0 . 59 x and (R2 = 0.99 ) and Which is showing good linearity, precision, accuracy and sensitivity, which might be used for determination heavy metals . The quantity of potassium bromate bread samples ranged from 0.38 to 13.72 ppm and therefore the amount of Ni in bread ranged from 0.66 to 2. 7 ppm the quantity of Cu ranged from 5 to 41 ppm and the quantity of Fe 0.003 ppm to 0.03 ppm en_US
