Antimony migration from polyethylene terephthalate (PET) containers into aqueous (distilled water, 3% acetic acid, 10% and 20% ethanol) and fatty food simulants (vegetable oil), as well as into vinegar, was studied. Test conditions were according to the recent European Regulation 10/2011 (EU, 2011). Sb migration was assayed by ICP-MS and HG-AFS. The results showed that Sb migration values ranged from 0.5 to 1.2μg Sb/l, which are far below the maximum permissible migration value for Sb, 40μg Sb/kg, (EU, Regulation 10/2011). Parameters as temperature and bottle re-use influence were studied. To assess toxicity, antimony speciation was performed by HPLC-ICP-MS and HG-AFS. While Sb(V) was the only species detected in aqueous simulants, an additional species (Sb-acetate complex) was measured in wine vinegar. Unlike most of the studies reported in the literature, migration tests were based on the application of the EU directive, which enables comparison and harmonisation of results.
研究了聚对苯二甲酸乙二醇酯（PET）容器中锑向水性（蒸馏水、3%乙酸、10%和 20%乙醇）和脂肪性食品模拟物（植物油）以及醋中的迁移情况。测试条件符合最近的欧洲法规 10/2011（EU，2011）。通过 ICP-MS 和 HG-AFS 测定 Sb 的迁移量。结果表明，Sb 的迁移值范围为 0.5 至 1.2μg Sb/l，远低于 Sb 的最大允许迁移值 40μg Sb/kg（EU，法规 10/2011）。研究了温度和瓶子重复使用等参数的影响。为了评估毒性，采用 HPLC-ICP-MS 和 HG-AFS 对 Sb 进行了形态分析。尽管 Sb(V)是在水性模拟物中检测到的唯一物种，但在葡萄酒醋中还测量到了另一种物种（Sb-醋酸盐络合物）。与文献中报道的大多数研究不同，迁移测试基于欧盟指令的应用，这使得结果可以进行比较和协调。
