As a result of the European Single Use Plastic Directive and as part of the transition to a circular economy, plastic food contact materials (FCMs) are being replaced, often by renewable plant-based materials. This research aimed to identify which chemical substances are present in plant-based materials. In 2022 a total of 28 samples of the latter materials from the Dutch market were analysed for 313 active substances from plant protection products, 47 per- and polyfluoralkyl substances (PFASs) and 27 heavy metals and other elements. Ten samples contained plant protection products that are not authorised in the EU. Most materials contained PFASs at trace or even high levels. Three out of four investigated sugar cane materials contained 6:2 fluorotelomer alcohol at levels up to 1.7 mg/kg. High contents of aluminium, manganese, iron, zinc, and barium were found. Other heavy metals, such as arsenic, lead and mercury were found in relatively low contents. A broad GC-MS screening was performed, which revealed the presence of plant extractable, plasticisers, antioxidants and hydrocarbons, which were not all authorised for FCMs, but may be present as non-intentionally added substances.
由于欧洲一次性塑料指令的实施，以及向循环经济转型的一部分，塑料食品接触材料（FCM）正在被替代，通常是由可再生的植物基材料替代。本研究旨在确定植物基材料中存在哪些化学物质。2022 年，对来自荷兰市场的 28 种此类材料进行了分析，共检测出 313 种来自植物保护产品、47 种全氟和多氟烷基物质（PFAS）以及 27 种重金属和其他元素的活性物质。10 种样品含有欧盟未授权的植物保护产品。大多数材料含有痕量甚至高水平的 PFAS。在 4 种被调查的甘蔗材料中，有 3 种含有高达 1.7mg/kg 的 6:2 氟调聚醇。还发现了大量的铝、锰、铁、锌和钡。其他重金属，如砷、铅和汞的含量相对较低。进行了广泛的 GC-MS 筛选，结果表明存在植物可萃取物、增塑剂、抗氧化剂和碳氢化合物，这些物质都没有被授权用于 FCM，但可能作为非故意添加物质存在。
