In recent decades, anthropic interventions have altered the cycle of natural processes that occur on the Earth's surface, with impacts that configure the physical environment. The objective of the research was to identify and analyze geoindicators (geochemical) of anthropogenic environmental changes in the environmental compartments (water and sediments) of the Botas River basin. The methodology was based on the selection of five points in the longitudinal profile of the river and laboratory analysis (bed sediment, plain and water) to determine the trace elements: Cr, Cu, Ni, Cd, Pb and Zn. The results indicated water and sediment pollution by Cr, Cu, Pb and Zn elements, based on National Oceanic and Atmospheric Administration (NOAA) refer...
