| Abstract | Atmospheric particulate matter (PM) is a pollutant composed by various metals, that when accumulated in the respiratory system may cause serious health problems. Methods IO-3.1 (metal extraction in PM) and IO-3.4 [metal determination by inductively coupled plasma optical emission spectrometry (ICP-OES)] are the recommended by the United State Environmental Protection Agency. With the intent to evaluate the performance of the method developed in our laboratory for the extraction of metal in PM with HNO3 p.a. bidistilled and determination by ICP-OES of Al, Ca, Cd, Cu, Cr, Fe, K, Mg, Mn, Na, Ni, Pb, Ti, V and Zn, validation was executed according to the criteria established by the INMETRO determining the parameters: selectivity, linearity, precision, accuracy, robustness, limits of detection and quantification, as well as the comparison of the efficiency and precision with IO-3.1 method. The results show that our method meets all validation criteria established by the INMETRO; furthermore, it shows to be equivalent to IO-3.1 method. |
