Abstract

Water Resources daily suffer with insertion of organic and inorganic contaminants. Among the inorganic sources of pollution, contamination with metals are worrying because some metals are presented toxic even in small amounts, causing bioaccumulation and biomagnification in the food chain. The present research aimed to evaluate the levels of metals and physical-chemical parameters in the Marreco and Panambi rivers, whose fountains are located in the urban area of Toledo -PR, in order to evaluate the possible impacts caused to these water sources. In order to do this, monthly determinations were performed on the metal content (Cu, Zn, Fe, Mn, Cd, Pb and Cr), as well as determinations on the physico-chemical parameters (turbidity, pH and total dissolved solids) in 5 points sample of two tributaries with urban springs of Toledo, PR. The results were compared with the maximum limits established by CONAMA 357/05 for Class 2 fresh waters. The results showed that Cd and Pb had concentrations above the allowed, indicating insertion and environmental contamination possibly by agricultural and urban activities nearby. In addition, values obtained for the turbidity are also in disagreement with the legislation, fact related to the sections being studied in urban perimeter, exposed to external influences from the most varied types of anthropic activities.
