Abstract

Over the last decade, the consumption of tea and herbal tea has gained more and more popularity across the globe, but the potential presence of chemical contaminants (e.g. pesticides, trace elements, synthetic drugs) may raise health concerns. This study analysed selected teas available in Belgian retail stores and performed a risk assessment for these samples. No chemical adulteration could be detected in dry tea material. More than 38% of the dry leaves samples contained at least one pesticide exceeding the maximal residue level (MRL) set by the EU. However, further risk assessment, based on the values of pesticide residues and the toxic trace elements encountered in the brew, demonstrate that the consumption of these teas will not give rise to health concerns. Nonetheless, attention should be given to the leaching potential of nickel from teas and the presence of arsenic in brews from algae containing teas.

比利时零售商店出售的茶叶样品中的农药、微量元素和药物以及急性和慢性接触的相关风险。

在过去十年中，茶和凉茶的消费在全球越来越受欢迎，但潜在的化学污染物(如农药、微量元素、合成药物)可能会引起健康问题。本研究分析了比利时零售商店中所选的茶叶，并对这些样品进行了风险评估。干茶原料中未检出化学掺假。超过38%的干叶样品中含有至少一种农药超过欧盟规定的最大残留水平。然而，进一步的风险评估，基于在冲泡中遇到的农药残留和有毒微量元素的值，表明这些茶的消费不会引起健康问题。尽管如此，应该注意从茶叶中浸出镍的可能性，以及从含有藻类的茶叶中酿造的茶中存在砷。

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.
