In recent years, a great intensification in the use of various elements especially in modern technology can be observed. However, the anthropogenic activities, including industrialisation, urbanisation or intensive agriculture, have led to the release of many of the elements into the environment. The consequence of the accumulation of the elements both in soil and water systems is their presence in the food chain. Inhalation and consumption of the contaminated food and beverages have been indicated as the main pathways of the exposure to many elements. Due to the fact, that tea is considered the second most popular beverage worldwide and its consumption is constantly increasing, it is crucial to evaluate the safety of the product, especially for toxic elements contamination. Thus, the aim of the project was to evaluate the contamination levels of rare earth elements (REEs) including lanthanides, scandium (Sc) and yttrium (Y) and also antimony (Sb), barium (Ba), boron (B), lithium (Li), tellurium (Te), thallium (Tl) and vanadium (V) in teas. Subsequently, the risk assessment was carried out. Additionally, the Fellowship provided hands-on training on the evaluation of applications of new biocides and participation in the science-based advises given to the Danish Food and Veterinary Administration, Danish Environment Protection Agency and Danish Medical Agency.
近年来，可以观察到各种元素的使用强度大幅增加，尤其是在现代技术中。然而，包括工业化、城市化或集约化农业在内的人类活动导致许多元素释放到环境中。这些元素在土壤和水系统中积累的结果是它们存在于食物链中。吸入以及食用受污染的食品和饮料被认为是接触许多元素的主要途径。鉴于茶被认为是全球第二大最受欢迎的饮品且其消费量在不断增加，评估该产品的安全性至关重要，尤其是对于有毒元素污染。因此，该项目的目的是评估茶叶中稀土元素（REEs）的污染水平，包括镧系元素、钪（Sc）和钇（Y），以及锑（Sb）、钡（Ba）、硼（B）、锂（Li）、碲（Te）、铊（Tl）和钒（V）。随后，进行了风险评估。此外，该奖学金提供了关于评估新型生物杀灭剂应用的实践培训，并参与了向丹麦食品和兽医管理局、丹麦环境保护局和丹麦医疗局提供的基于科学的建议。
