An accurate and reproducible method for direct determination of vanadium (V) in wine using graphite furnace atomic absorption spectrometry (GFAAS) is described. This method gave results insignificantly different from those obtained using dry mineralization of wine samples, with a detection limit of 42 pg. A total of 68 wine samples from different regions of France and California were analysed. Vanadium levels ranged from 7.0 to 90.0 micrograms/l in red and from 6.6 to 43.9 micrograms/l in white wines. The method was also adapted to the determination of vanadium levels in 12 grape samples from different varieties after acid mineralization. Vanadium content varied from 2 to 17 micrograms/kg for white and from 5 to 11 micrograms/kg for red varieties. Our data indicate that wine storage conditions may increase vanadium content. The contribution of wine consumption to daily vanadium dietary intake of the French population was estimated to be 11 micrograms/day per individual.
描述了一种使用石墨炉原子吸收光谱法（GFAAS）直接测定葡萄酒中钒（V）的准确且可重复的方法。该方法所得结果与使用葡萄酒样品干灰化法获得的结果无显著差异，检测限为42皮克。对来自法国和加利福尼亚不同地区的68个葡萄酒样品进行了分析。红葡萄酒中钒含量范围为7.0至90.0微克/升，白葡萄酒中为6.6至43.9微克/升。该方法还适用于酸消解后对12个不同品种葡萄样品中钒含量的测定。白葡萄品种的钒含量为2至17微克/千克，红葡萄品种为5至11微克/千克。我们的数据表明，葡萄酒的储存条件可能会增加钒含量。据估计，法国人群通过饮用葡萄酒摄入的钒对每日膳食钒摄入量的贡献为每人每天11微克。
