Abstract: The intensity of the current demand for water resources makes its management process necessary. In this sense, the emergence of the development of studies and programs aimed at biomonitoring for their protection is understood, threatened by the environmental impacts resulting from urbanization. This work aims to analyze the technical feasibility of environmental biomonitoring in the urban area of the Cascavel river basin, through the occurrence, concentration and correlation of heavy metals Zinc (Zn), Magnesium (Mg), Manganese (Mn), Chromium (Cr), Nickel (Ni) and Lead (Pb) in the Egeria Densa aquatic macrophyte, sediment and water, using the Atomic Absorption Spectrometry - EAA. In addition, to verify possible polluting sources of heavy metals at the collection points and the surrounding area and to obtain specific physicochemical parameters of water in the proposed study area. Six strategic points were defined for the collection of aquatic macrophytes, sediment and water samples with different geomorphological characteristics and for land use. Six samples were collected between December 2020 and May 2021. The parameters for water and sediment are within normal levels, the values found in the plant samples indicate contamination levels for Zn, Mn and Mg, in addition to Pb. The anthropogenic sources of heavy metals in the study area come from industrial solid waste, being more evident at the northernmost points downstream; and urban areas at the points chosen upstream. The methodology used was efficient to quantify the toxicity levels in the proposed analysis elements.
