Physicochemical characterization and presence of heavy metals in the trout farming area of Lake Titicaca, Peru

<p>Certain areas of Lake Titicaca exhibit signs contamination from urban drainage, mining tailings, and waste trout cage farming. The objective this study was to determine the physicochemical conditions water concentration heavy metals in sediments a (<em>Oncorhynchus mykiss</em>) farming area Puno Bay, Titicaca. Water samples were collected at depths 1, 5, 10, 15 meters surface, as well bottom lake. Additionally, taken 500 breeding area, where no activities took place. carried out over period 10 months. Some physical-chemical measurements situ using multiparametric device, while others IMARPE’s laboratory. results indicate that quality does not exceed tolerance limits recommended by Environmental Quality Standards - ECA Peru. pH 8.79 dissolved oxygen 6.81. (Hg, Cd, Pb, Zn, Cu) found within permissible compared ISQG Canada Standard. However, As, 41 mg kg<sup>-1</sup>, exceeded limit. Uncontrolled trends production volumes could compromise sustainability.</p>
