Resumo
From validation studies, it was possible to estimate a measurement uncertainty of
several elements such as Al, Ba, Ca, Cu, Cr, Cd, Fe, Mg, Mn, Ni and K in water samples from
Guarapiranga Dam. These elements were analyzed by optical emission spectrometry with
inductively coupled plasma (ICP-OES). The value of relative estimated uncertainties were
between 3% and 15%. The greatest uncertainty contributions were analytical curve, and the
recovery method, which were related with elements concentrations and the equipment response.
Water samples analyzed were compared with CONAMA Resolution #357/2005.
