Milk, dairy and cereal products are the main contributors to total chromium (Cr) dietary exposure in France (up to 42% for children), but there have been no assessments regarding dietary exposure to Cr(VI) or Cr(III) to date. To assess dietary exposure, total chromium and Cr(VI) were determined in 68 different brands and origins of milk, dairy and cereal products. Cr(VI) was not detected in these samples despite the very high sensitivity of the method used. It was therefore assumed that total chromium is only present in the Cr(III) form. Total chromium levels were quantified in 58% of milk and dairy products and 76% of cereal products. The highest mean levels were found in breakfast cereals and cheese (269 and 25 µg Cr /kg fresh weight, respectively). The findings pointed out that the dietary exposure levels of Cr(III) and Cr(VI) were well below the health-based guidance values.
牛奶、乳制品和谷物产品是法国总铬（Cr）膳食暴露的主要来源（儿童最高可达 42%），但迄今为止，尚未对 Cr(VI)或 Cr(III)的膳食暴露进行评估。为了评估膳食暴露，对 68 种不同品牌和来源的牛奶、乳制品和谷物产品中的总铬和 Cr(VI)进行了测定。尽管使用的方法非常灵敏，但这些样品中均未检测到 Cr(VI)。因此，假设总铬仅以 Cr(III)的形式存在。在 58%的牛奶和乳制品以及 76%的谷物产品中定量了总铬的含量。在早餐麦片和奶酪中发现了最高的平均水平（分别为 269 和 25 µg Cr/kg 鲜重）。研究结果表明，Cr(III)和 Cr(VI)的膳食暴露水平远低于基于健康的指导值。
