    The objective of this study was to determine the toxicological concentrations of cadmium, lead, and arsenic in agricultural soil and radish (Raphanus sativus) in the Huachipa-Nievería area of the Lurigancho-Chosica district, 2022. Methodology: The method used was hypothetical-deductive, with a quantitative approach. It was a basic, non-experimental, correlational, and cross-sectional study at a descriptive level. Five soil samples were collected according to the Agricultural Soil Sampling Manual from MINAM to conduct this study. The study area was 300 m², and radishes were collected from the same points. The analytical method was performed in a laboratory using an ICP-OES device to provide concentration values for cadmium, lead, and arsenic in soil and radish. Results: Statistical tests were performed: T-student tests for soil and radish. Soil: Cadmium concentrations were determined with p=0.00 < 0.05; lead concentrations, p=0.00 < 0.05; arsenic concentrations, p=0.003 < 0.05. Therefore, cadmium, lead, and arsenic exceed the ECA limits for soil. Radish: Cadmium concentrations, p=0.096 > 0.05; lead concentrations, p=0.025 < 0.05; arsenic concentrations, p=0.49 > 0.05. Thus, cadmium and arsenic do not exceed permissible limits, while lead exceeds the permissible limit set by the Codex Alimentarius. Conclusion: It was found that radishes had lead concentrations in the soil that exceeded the limits allowed by the Codex Alimentarius.
