Determinación De Metales Pesados en Las Aguas Del Río Ananea Debido a La Actividad Minera Aurífera, Puno-Perú

Abstract: Los metales pesados se encuentran entre los contaminantes ambientales más tóxicos de los últimos tiempos, debido a su permanencia y tendencia a acumularse en los organismos acuáticos. El objetivo de este trabajo fue determinar los niveles de Arsénico, Cadmio, Cobre, Cromo, Mercurio, Plomo y Zinc del río Ananea. Se programaron tres campañas de muestreo, realizados en los meses de marzo, junio y agosto (período de estiaje). Las concentraciones de los metales pesados se determinaron por espectrometría de absorció… Show more

“…Heavy metal ions found in mine tailings, such as cadmium, copper, chromium, lead, and mercury ions, are toxic to organisms even at low concentrations [ 9 ]. However, certain microorganisms, such as bacteria and yeasts isolated from areas contaminated by heavy metals, have great potential for adaptation to these metal ions via various resistance mechanisms, such as activation of the redox antioxidant system (AORS) to reduce reactive oxygen species (ROS) and chelation of metal ions by phytochelatins via glutathione (GSH) and metallothionein (MT) [ 10 , 11 , 12 ].…”

“…[ 22 ] have pointed out that the presence of metals in the Suches River in the Puno Region is due to discharges generated by typical mining activities, as well as the mineralogical composition and natural weathering of rocks in the area, which negatively impact water quality. Similarly [ 23 ], found the same in various rivers in the Puno Region, and heavy metals such as Cu, Zn, Pb, Cd, As, and Hg were found in the water of the inner bay of the city of Puno[ 24 ]. [ 25 ]; reported high concentrations of heavy metals in the Puno Region that exceed the maximum permissible limit (MPL).…”
