Inorganic arsenic is a chronic exposure carcinogen. Analysis of UK baby rice revealed a median inorganic arsenic content (n=17) of 0.11 mg/kg. By plotting inorganic arsenic against total arsenic, it was found that inorganic concentrations increased linearly up to 0.25 mg/kg total arsenic, then plateaued at 0.16 mg/kg at higher total arsenic concentrations. Inorganic arsenic intake by babies (4-12 months) was considered with respect to current dietary ingestion regulations. It was found that 35% of the baby rice samples analysed would be illegal for sale in China which has regulatory limit of 0.15 mg/kg inorganic arsenic. EU and US food regulations on arsenic are non-existent. When baby inorganic arsenic intake from rice was considered, median consumption (expressed as microg/kg/d) was higher than drinking water maximum exposures predicted for adults in these regions when water intake was expressed on a bodyweight basis.
无机砷是一种慢性暴露致癌物。对英国婴儿米粉的分析显示，17份样本中无机砷含量的中位数为0.11毫克/千克。通过绘制无机砷与总砷的关系图发现，无机砷浓度在总砷含量达到0.25毫克/千克之前呈线性增加，然后在总砷含量较高时稳定在0.16毫克/千克。根据当前的膳食摄入规定，对4至12个月大婴儿的无机砷摄入量进行了评估。结果发现，所分析的婴儿米粉样本中有35%在中国销售是违法的，因为中国对无机砷的监管限值为0.15毫克/千克。欧盟和美国没有关于砷的食品法规。当考虑婴儿从米粉中摄入的无机砷时，以体重为基础计算水摄入量时，婴儿无机砷的中位数摄入量（以微克/千克/天表示）高于这些地区预测的成年人饮用水最大暴露量。
