Abstract: Lead was determined directly in wine by flow injection hydride-generation AAS and in beer and cider with prior online microwave oven treatment. Other alcoholic beverages were first microwave digested with HNO3 at 120°C for 90 min. Lead hydride was generated in HNO3/H2O2 medium using NaBH4 and was carried by Ar to the atomization cell where it was heated by an acetylene-air flame (no details given of temperature). The Pb line at 217.0 nm was monitored. The detection limit was 10^-12 µg/l Pb and the RSD were 4-8% (n = 10). The concentrations of Pb in 70 wines and 64 other beverages are reported and discussed.
