Determinar la distribución geoespacial de metales pesados con aplicación ambiental de los sedimentos fluviales del rio Puyango Sector Santa Rufina

Abstract

Abstract: The present investigative work of end of graduation has the purpose of determining the environmental contamination by mining existing in the Puyango River, Santa Rufina Sector. For the development of our objectives, certain research phases were determined, such as the field, which consisted of searching for a method for the extraction of sediment samples,a laboratory stage in which we worked with the samples obtained, partially disintegrating them through acid digestion and subjecting them to a measurement of heavy metals (atomic absorption method) and a geostatistical analysis of the results obtained by the AA. These parameters obtained determined mostly high environmental contamination by the following metals: Zinc (Zn), Lead (Pb), Copper (Cu) and a slight contamination of Cadmium (Cd), with no evidence of contamination by Mercury (Hg). These analyses establish whether the explored area shows such contamination by mining tailings or are products of natural leaching, in addition to presenting data of anomalies or outlier in the sediment extraction points.
