    Currently, evaluating metal levels in fish is a topic of national and global public health interest. Since a large number of metals contaminate rivers, lakes, and seas, it is important to determine if these products comply with the maximum permissible limits for mercury and arsenic established by the National Fisheries Health Service (SANIPES) of Peru, and thus evaluate if there is a risk to the consuming population. Methods: To determine mercury, a mercury hollow-cathode lamp was used at a wavelength of 253.70 nm via a graphite furnace. For arsenic determination, an arsenic hollow-cathode lamp was used at a wavelength of 193.70 nm via a hydride generator. Result: No values were found to exceed the maximum permissible limits for mercury and arsenic. Conclusion: The pejerrey (Odontesthes regia) sold at the Ancón fishing terminal is suitable for optimal human consumption.

    Principio de permisibilidad del Códex Alimentarius de arsénico y mercurio en “jurel” (Trachurus murphyi) y “bonito” (Sarda Chiliensis) comercializados en el terminal pesquero de Ventanilla, Lima-2024

    Heavy metals are considered a serious global problem, generated primarily by human activities, where fish are indicators of arsenic and mercury contamination; these values are regulated by the Codex Alimentarius to ensure safe consumption. Therefore, the objective of the study was to determine the permissibility of arsenic and mercury in horse mackerel (Trachurus murphyi) and bonito (Sarda chiliensis) sold at the Ventanilla fishing terminal, Lima-2024. The methodology was a descriptive, non-experimental, cross-sectional study, where 10 samples of “jurel” and 10 of “bonito” from the Ventanilla fishing terminal were worked with. These samples were analyzed to quantify total arsenic and mercury using the atomic absorption technique. The results indicated that the mercury concentrations in “jurel” and “bonito” were 16,722 +- 2.206 and 15,44 +- 2.229 ug/kg, respectively; and the arsenic concentrations in “jurel” and “bonito” were 57,837 +- 20.005 and 59,808 +- 15,713 ug/kg, respectively. In conclusion, the arsenic and mercury values in “jurel” and “bonito” fish were within the maximum permissible limits established by the Codex Alimentarius.
