Given the widespread appeal of baked goods globally, including in Bangladesh, an experimental investigation was carried out to quantify food contaminants due to the conjecture that they can be carcinogenic and their ingestion through diet may have health implications. The potential adverse effects of acrylamide and potassium bromate especially their possible carcinogenicity in human through dietary exposure necessitate their monitoring. In total, one hundred seven samples were collected from different locations within Dhaka city and various districts of Bangladeshconsisting of 39 bread, 13 burger bun, 33 cake, 10 pizza and 12 naan samples. The analysis also highlighted heavy metal contamination of baked goods as a concern to food safety. The bromate concentration of the samples was determined utilizing the spectrophotometric approach, whilst the heavy metal (Pb, Cu, Zn) concentration in the digested samples were profiled using flame atomic absorption spectrophotometer. The study reports the analysis of acrylamide levels in selected samples by using gas chromatograph equipped with electron capture detector. The amount of bromate varied considerably in the ranges from0.660±0.012- 5.53±0.242, 0.860±0.003-1.69±0.003, 0.839±0.005-6.182±0.010,0.922±0.007-4.356±0.012 and 0.639±0.006-5.370±0.022 μg/g in the bread, burger bun,cake, pizza and naan samples, respectively. The recoveries from the samples spiked with bromate at low levels satisfactorily ranged from 85-108%. Acrylamide concentrations in thirty-six different samples were found to be ranged from 0.96-2998.7 µg/ kg which is very alarming. The recoveries of acrylamide in samples ranged between 62.0-83.1%. The amounts of heavy metals in the samples varied from 4.97-9.36, 1.15-4.68 and 7.32-12.92 mg/kg for lead, copper and zinc, respectively. An extremely high concentration of lead above the permissible level was discovered. The moisture and ash content of the samples were found to be 11.93-49.34 and 0.62-2.64%, respectively. The bread samples were found to contain the carcinogens potassium bromate, acrylamide and trace metal levels that could threaten the health of Bangladeshi population over prolonged regular consumption.
