    The objective of this research was to determine the concentration of lead and arsenic in candies—specifically chewing gums, hard candies, and soft drinks—using atomic absorption in Metropolitan Lima, 2021. The methodology followed a quantitative approach, applied type, and quasi-experimental design. The sample population consisted of 10 chewing gums, 10 hard candies, and 10 soft drinks, which were analyzed using atomic absorption spectrophotometry. Results: The average lead concentration in imported chewing gum was 0.0540 mg/kg, in imported hard candies 0.0520 mg/kg, and in imported soft drinks 0.0440 mg/L. For national products, the average lead concentration was 0.0480 mg/kg in chewing gum, 0.0340 mg/kg in hard candies, and 0.0460 mg/L in soft drinks. Regarding arsenic, the average concentration in imported chewing gum was 0.00380 mg/kg, in imported hard candies 0.00640 mg/kg, and in imported soft drinks 0.00180 mg/L. For national products, the average arsenic concentration was 0.00740 mg/kg in chewing gum, 0.00480 mg/kg in hard candies, and 0.00480 mg/L in soft drinks. Conclusion:The concentrations of lead and arsenic in the analyzed candies did not exceed the maximum permissible limits established by the Codex Alimentarius.
