Abstract

Los relaves mineros, es una de las más peligrosas formas de contaminación generadas porla explotación minera básicamente en las cabeceras de cuencas, y que afectan principalmente alos recursos hídricos y agrícolas; por lo que en la presente investigación se trata de cuantificar laabsorción de los metales pesados Pb y Cd por el rabo de zorro Lolimun multiflorum L. (Poaceae),utilizando suelos contaminados por material de relave que contienen metales pesados, provenientesde la zona de Samne, La Libertad, Perú. Para determinar la concentración de los metales pesadosPb y Cd, se utilizó la metodología de la espectrofotometría de absorción atómica. Los resultadosencontrados, indican que los valores de la concentración de los metales pesados absorbidos Pb y Cd,siguieron la siguiente tendencia: Pb > Cd

Abstract

Pollution produced by the mining industry, which are stored in systems known as relaveras, as well as direct dumping into rivers and subsequent use of water resources in agriculture, is one of the most dangerous forms of affecting water and agricultural ecosystems ; So the present research tries to quantify the amount of Cu, Cd, Pb and As absorbed by the root, stem and leaves of the Helianthus annus L. (Asteraceae) sunflower using soils contaminated by tailings material from the Samne area. Absorption of the heavy metals copper, cadmium, lead and arsenic present in agricultural soil samples containing 25, 50, 75 and 100% of tailings absorbed by sunflower was determined; Following the methodology proposed by Aquino et al. 1989. The results showed that the bioconcentration values of the heavy metals Cu, Cd, Pb and As followed the following trend: Cu> As> Pb> Cd and that the bioremediation effect was higher for the copper heavy metal; As well as drastic saturation occurred at the level of cadmium and lead metals, and that the root was the organ of the plant with the greatest power of phytoremediation.

Abstract

Pollution generated by the mining and metallurgical industry is one of the most dangerous forms of pollution that mainly affects the headwaters of basins, and that negatively impacts on water and agricultural resources; Therefore, in this research, the absorption of heavy metals Pb, As and Cd by corn (Zea mays L.) and beet (Beta vulgaris L.) is quantified, using soils contaminated by mining tailings that contain heavy metals, from the Samne area, La Libertad, Peru. To determine the concentration of the heavy metals Pb, As and Cd, the methodology of atomic absorption spectrophotometry was used. The results found indicate that the maximum concentration values of heavy metals were determined in the beet with values of 432,95 mg/ kg for Pb, 3,89 mg/ kg for as and 13,88 mg/ kg for Cd in the root organ; following the absorption trend: Pb > Cd > As, with Pb having the highest absorption level at 65, 95 and 125 days of experimentation.
