    The purpose of the work was to determine the concentrations and risks of lead, mercury, and arsenic toxicity in drinking water for human consumption in the district of La Unión Leticia in 2023. For the analysis of the water, inductively coupled plasma mass spectrometry (ICP-MS) was used, and the development of a method to assess the health risks determined an average lead concentration of 0.00031 mg/L, with a minimum value of 0.00013 mg/L and a maximum value of 0.00013 mg/L. It was done, 0.00103 mg/L, not exceeding the permissible value according to the WHO and water quality standards. The mercury concentration was 0.00002 mg/L with a minimum value of 0.00001 mg/L and a maximum value of 0.00002 mg/L. In accordance with the WHO and water quality standards, it was finally determined The average arsenic concentration was determined to be 0.02745 mg/L, with a minimum of 0.022523 mg/L and a maximum of 0.03300 mg/L. This exceeds the regulatory and permitted limits for water quality and the WHO. This concentration was applied to the health risk assessment, resulting in a PI < 1. This indicates a risk of arsenic toxicity in the drinking water for human consumption in the district of La Unión Leticia in the year 2023.
