    Heavy metals are among the most widespread environmental contaminants worldwide, with Peru being one of the countries affected due to its extensive mining sector. Currently, Peru lacks regulations regarding permissible limits of these toxic substances in food. The present study aimed to determine the concentration of cadmium and lead in the egg white and yolk of quail eggs (Coturnix coturnix) sold in the busiest markets of the San Martin de Porres district. A total of twenty quail eggs were sampled, and both the egg white and yolk were analyzed together using Graphite Furnace Atomic Absorption Spectroscopy. The results were then compared with the Mexican Official Standard NOM-159-SSA1-1996 for cadmium (0.05 mg/kg) and the MERCOSUR Technical Regulation for lead (0.1 mg/kg). The results for cadmium ranged from 0.04 mg/kg to 0.14 mg/kg, with a mean of 0.083 mg/kg, where 7 samples (35%) were below the maximum permissible limits, and 13 samples (65%) exceeded the maximum allowable values. Regarding lead, the values ranged from 0.08 mg/kg to 0.26 mg/kg, with a mean of 0.150 mg/kg, where 2 samples (10%) were below the maximum permissible limits, and 18 samples (90%) exceeded the maximum allowable values. In conclusion, the levels of cadmium and lead in quail eggs exceed the maximum permissible limits established by the aforementioned standards.
