This study reports results of total arsenic (As) and various As species in 75 samples of cereals and cereal products bought on the Belgian market. In addition to rice, the samples were wheat, pasta, bread and some breakfast cereals. The inorganic species arsenite (As) and arsenate (As), and the organic As compounds dimethyl arsinate (DMA) and monomethyl arsonate (MA) were the only As species detected. Mean As was 0.150 ± 0.089 mg kg in rice and 0.012 ± 0.008 mg kg in the non-rice cereals. The inorganic arsenic fraction (As = As + As) dominated in all samples and was in the range 55%-100%. Significantly higher As and As concentrations were observed in white rice and brown rice compared to Basmati rice. Within the group of non-rice cereals bread and pasta showed significantly lower concentrations compared to wheat. All 30 rice samples were conform to the European maximum limits for As, laid down in Commission Regulation (EU) 2015/1006. Although regulatory limits certainly can help to protect consumer health, our results suggest that the currently fixed European maximum levels are, in Belgium, not expected to have any impact on the human exposure to As, which is a known carcinogenic substance.
本研究报告了在比利时市场购买的 75 份谷物和谷物制品中总砷（As）和各种 As 形态的结果。除了大米，这些样本还包括小麦、意大利面、面包和一些早餐麦片。检测到的无机砷形态有亚砷酸盐（As）和砷酸盐（As），以及有机 As 化合物二甲砷酸（DMA）和一甲基砷酸（MA）。大米中的平均 As 含量为 0.150 ± 0.089mg/kg，非大米谷物中的平均 As 含量为 0.012 ± 0.008mg/kg。所有样品中均以无机砷为主（As = As + As），其范围为 55%-100%。与 Basmati 大米相比，白米和糙米中的 As 和 As 浓度明显更高。在非大米谷物组中，与小麦相比，面包和意大利面的浓度明显更低。所有 30 份大米样品均符合欧盟委员会法规（EU）2015/1006 规定的 As 最大限量。虽然监管限制肯定有助于保护消费者健康，但我们的研究结果表明，目前在比利时设定的欧洲最大水平预计不会对人体暴露于 As 产生任何影响，As 是一种已知的致癌物质。
