摘要：

The levels of Co, Cr, Cu, Fe, Pb and Zn were determined simultaneously in several brands of bottled and canned beer, by inductively coupled argon plasma atomic emission spectrometry, with previous mineralization with conc. HNO3/H2O2 (30%). The results showed the good quality of the beers with respect to their metal contents. An alternative digestion method, with conc. HNO3 and O3, was also studied.
