The purpose of this work is to present the results of the metal monitoring in Igapó Lakes, in the city of Londrina, as well as to evaluate the potential of a portable EDXRF system for the determination of total metal concentration in water, as an alternative analytical methodology, compared to AAS. Considering all the sampling points, it was possible to quantify by EDXRF, the following range of concentrations, in mg L?¹, for Ca (0.043 – 0.021), Ti (0.137 – 0.014), Mn (0.052 – 0.008), Fe (1.046 – 0.035), Ni (0.012 – 0.010), Cu (0.010 – 0.007) and Zn (0.070 – 0.007). AAS and EDXRF results were complementary, generating relevant conclusions about the analysis.
