Abstract

In this study, a method has been used to prepare and evaluate the content of some metals in samples of eye shadow. The samples were manufactured in different countries (Brazil, China and USA). The sample preparation was performed using dilute nitric acid and a hot block. The Pb content was measured using graphite furnace atomic absorption spectrometry (GFAAS), and the quantification of Cd, Co, Cr, Cu and Ni was performed using inductively coupled plasma optical emission spectrometry (ICP OES). Chemometric tools were used for multivariate optimisation and to perform an exploratory analysis according to the metal concentration levels. Some samples presented metal concentrations above the values indicated by the FDA (USA) and ANVISA (Brazil). (AU)
