Abstract

A non-targeted convenience survey was conducted in 2021 to estimate the range of total arsenic (As), cadmium (Cd), total mercury (Hg) and lead (Pb) concentrations in ready-to-eat baby foods. Four hundred samples were purchased both online and in brick-and-mortar retail. Samples included both organic and non-organic products, packaged in glass or plastic jars and foil or plastic pouches. Samples were analysed by acid assisted microwave digestion and ICP-MS with an emphasis on ultra-low detection limits. Limits of quantification were 2.26, 1.31, 0.72, and 3.14 µg/kg (ppb) for As, Cd, Hg and Pb, respectively. The median concentrations of As, Cd, Hg, and Pb in tested products were 2.60, 1.81, 0.09, and 1.38 µg/kg, respectively. Foods containing rice were more likely to contain arsenic. Foods with leafy greens, such as spinach and kale, were more likely to contain cadmium and foods with root vegetables had the highest concentrations of lead.

2021年美国即食婴儿食品中有毒元素的调查。

2021年进行了一项非目标便利调查，以估计即食婴儿食品中总砷(As)、镉(Cd)、总汞(Hg)和铅(Pb)的浓度范围。网上和实体零售店共购买了400个样品。样品包括有机和非有机产品，包装在玻璃或塑料罐和铝箔或塑料袋中。采用酸助微波消解法和ICP-MS对样品进行分析，并强调超低检出限。As、Cd、Hg和Pb的定量限分别为2.26、1.31、0.72和3.14µg/kg (ppb)。测试产品中砷、镉、汞和铅的中位数浓度分别为2.60、1.81、0.09和1.38µg/kg。含有大米的食物更有可能含有砷。含有绿叶蔬菜的食物，如菠菜和羽衣甘蓝，更有可能含有镉，而含有根茎类蔬菜的食物中铅的浓度最高。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
