Polycyclic aromatic hydrocarbons (PAHs) are toxic, carcinogenic compounds formed during food processing at high temperatures. This study analysed 16 priority PAHs in 31 commercial chip samples (18 corn and 13 potato) and evaluated dietary exposure and associated health risks. Most PAHs were detected, and benzo[a]pyrene, recognized as the most carcinogenic and a key marker of contamination, was showed the highest concentrations (1.07 +/- 0.78 & micro;g/kg in corn and 1.08 +/- 0.55 & micro;g/kg in potato). Total PAHs (E4, E8, E16) were consistently higher in potato chips, with average concentrations of 1.59, 2.63 and 4.27 & micro;g/kg, respectively. Chronic daily intake (CDI) and hazard index (HI) were below safety limits, and incremental lifetime cancer risk (ILCR) was acceptable under low and moderate consumption. Margin of exposure (MOE) values remained above 10,000 in all cases, indicating no significant carcinogenic concern. However, ILCR exceeded 1.0 & times; 10-5 at 100 g/day, highlighting consumption as a key risk factor. Thus, optimising frying conditions could further reduce exposure.
