Evaluation of total suspended load (CST) and metals in the basin of Pinhalzinho II stream in Umuarama - PR

To evaluate the anthropogenic influence on water quality in the basin of the Pinhalzinho IIstream in the northwest Umuarama Paranaense, we sought in this work, to determine the total suspendedload (CST) and the concentrations of metals: Cu, Mn, Fe, Ni, Cr, Pb, Cd, Se and Zn in the waters. For this purpose we selected four sampling points in the basin. Water samples were collected seasonally in order to analyze all the seasons, due to different weather conditions. Partial results show higher Fe and Mn, which lie above the values allowed by the CONAMA Resolution 357/2005. The total suspended load is mainly composed of organic matter.
