Caracterización ambiental del Arroyo Sarandí. Una interpolación espacial
description The Sarandi stream traverses along areas of dense population and industrial settlements. During his path receives numerous industrial discharges, that have little or no treatment. Because of these continuous discharges of effluents from industries in surrounding areas, the Sarandi stream has various heavy metals such as chromium, zinc, copper, lead and nickel. Depending on its concentration, these metals have harmful effects on health and the ecosystem. In this context, to determine the current environmental status of Sarandi stream, 17 sediment samples were taken at three sites over a period of 8 months. The sampling sites were located equidistantly at the intersection of the stream with Heredia, La Blanqueada and Sargento Ponce streets. The samples were analyzed by atomic absorption for detection of chromium, zinc, copper, lead and nickel in the Environmental Laboratory of the Municipality of Avellaneda. Obtained values were analyzed in a GIS environment to assess their spatial distribution, interpolating the obtained values by IDW (Inverse Distance Weighted). Through this technique, thematic maps were rendered with the distribution of heavy metals in the section of stream analyzed, including predictions of concentrations of these metals in areas where the stream is tubed. The results indicate that the highest concentrations of metals are in the section between Heredia and La Blanqueada streets, varying the pattern of distribution of concentrations between La Blanqueada and the stream mouth. Chromium is the metal that has higher average concentration in sediments. Also high zinc concentration values were obtained throughout the course of the stream, but copper, nickel and lead has a lower concentrations.
