The present study aimed to determine the level of Lead (Pb) concentration in three critical components in the Hualgayoc River basin, Cajamarca department: water, forage, and bovine milk. The determination will be carried out using the AOAC 972.25 method (Codex general method) - Atomic Absorption Spectrophotometry, Type II. Permissible concentration limits for Lead (Pb) were established as follows: ≤ 0,05 mg/L for animal drinking water, ≤ 0,02 mg/kg for milk, and < 30 ppm for forage. The results of the water samples varied by season. During the dry season, they were <0,001 ppm (mg/L), and during the rainy season, the results of the samples at points 2 to 6 did not exceed the maximum permissible limit of 0,05 mg/L. However, the sample taken at point 1 exceeded the maximum permissible limit for the presence of lead in water for pasture irrigation and livestock feeding by 0,005 mg/L. Similarly, the results obtained for milk samples taken in both the dry and rainy seasons did not exceed the maximum permissible limit of 0,02 mg/kg. Finally, the results of forage samples collected during the dry season at points 1, 2, 3, and 6 were below the permissible limit, while at points 4 and 5, the lead concentration was 401,10 mg/kg and 305,70 mg/kg, respectively, exceeding the permissible limit of 30 mg/kg for forage intended for animal consumption. During the rainy season, no presence of lead (Pb) was detected in the 6 samples.
