Evaluación de la concentración de metales pesados en las aguas superficiales del río chacapalca para fines de riego. Rev. Bol. Quim [online]. 2023, vol.40, n.4, pp.1-8.

Evaluation of the concentration of heavy metals in the surface waters of the Chacapalca river for irrigation purposes. The concentration of heavy metals was evaluated as possible contaminants in the bed and channel of the Chacapalca River, until its drainage into Lake Titicaca. Concentrations above the norm negatively impact surrounding populations, affecting various human activities. Two geographical sampling points of surface waters were defined, RChac1 and RChac2 according to the sampling protocol. The monitoring was carried out in two periods from 2017 to 2018, to evaluate the seasonal variation of the most notable parameters with the highest concentration determined analytically in situ. The results obtained demonstrated that there are no high concentrations of cadmium, lead and mercury in the two aforementioned study points. However, the point RCac1 can be considered as a critical point.
