Abstract

This study aimed to determine 9,10-anthraquinone (AQ) levels in Indonesian tea products from different manufacturers and assess the AQ's associated health risks. AQ levels increased significantly during withering and drying stages, using pinewood as a heat source. Generally, black tea was highly contaminated by AQ followed by green tea, oolong tea, and white tea. Out of a total of 116 samples from manufacturers using wood pellets as a heat source, 13% (15/116) of samples were contaminated with AQ exceeding the EU maximum residue level (MRL), and after accounting for measurement uncertainty, this value decreased to only 2% (2/116) that were deemed non-compliant. In contrast, 88% (57/65) and 50% (7/14) of tea samples were contaminated with AQ exceeding the EU MRL when manufacturers used pinewood and palm kernel shells as heat sources, respectively. However, based on our estimation, the risk level due to AQ exposure from Indonesian tea is still manageable, as indicated by calculating incremental lifetime cancer risk, <10⁻⁶ across all conditions studied (age group, type of tea, and heat source).

期刊介绍： Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs. The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following: -Adverse physiological/biochemical, or pathological changes induced by specific defined substances -New techniques for assessing potential toxicity, including molecular biology -Mechanisms underlying toxic phenomena -Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability. Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
