    The objective of this research was to evaluate the concentration of mercury and lead in Sarda chiliensis chiliensis ("bonito") and Scomber japonicus peruanus ("mackerel") sold at the Ventanilla fishing terminal. The study followed a non-experimental, descriptive, and cross-sectional design. A quantitative method was used to determine the concentration of mercury and lead in samples collected from the stalls at the Ventanilla fishing terminal. The samples were analyzed using the atomic absorption spectrophotometry method. The results were compared with the limits established by the Codex Alimentarius, SANIPES, and the European Union. The maximum and minimum lead concentrations in Sarda chiliensis chiliensis samples were 0.397 mg/kg and 0.0 mg/kg, respectively. For Scomber japonicus peruanus samples, the maximum and minimum lead concentrations were 0.369 mg/kg and 0.102 mg/kg, respectively. Regarding mercury, the maximum and minimum concentrations in Sarda chiliensis chiliensis samples were 0.558 mg/kg and 0.110 mg/kg, respectively, while for Scomber japonicus peruanus, the concentrations were 0.410 mg/kg and 0.058 mg/kg, respectively. Lead concentrations in Sarda chiliensis chiliensis samples exceeded permissible limits by 10% (n=1) and by 20% (n=2) in Scomber japonicus peruanus samples. Regarding mercury, no sample exceeded permissible limits. Conclusion: The samples of Sarda chiliensis chiliensis and Scomber japonicus peruanus sold at the Ventanilla fishing terminal contain concentrations of lead and mercury, with lead concentrations exceeding the maximum permissible limits.
