Abstract

Tea is one of the most common drinks, consumed for its pleasant flavour and several medicinal values. The present study aimed to determine the levels of trace elements in tea products marketed in the Saharan region of Ouargla, Algeria and to evaluate the health risks associated with its regular consumption in adults and infants. To this aim, 78 tea samples were analysed by Inductively Coupled Plasma - Mass Spectrometry. Tea samples appeared to be contaminated by lead (0.73 ± 0.08 µg g^-1) and aluminium (0.22 ± 0.02 µg g^-1). Cadmium, arsenic, mercury, cobalt, manganese, nickel, chromium, zinc and copper were also detected. General linear model analysis indicated that black tea samples were the most contaminated. Tea samples packed in tea bags were the most contaminated with arsenic, aluminium and manganese. The hazard index was 0.28 and 1.33 for adults and for infants, respectively, indicating adverse non-carcinogenic effects in infants.

阿尔及利亚瓦尔格拉茶叶中的微量元素及健康风险评估。

茶是最常见的饮品之一，因其风味宜人和多种药用价值而被人们饮用。本研究旨在确定阿尔及利亚瓦尔格拉撒哈拉地区市场上销售的茶叶产品中的微量元素水平，并评估成人和婴儿经常饮用茶叶对健康造成的风险。为此，采用电感耦合等离子体质谱法对 78 个茶叶样本进行了分析。茶叶样本似乎受到了铅（0.73 ± 0.08 µg g-1）和铝（0.22 ± 0.02 µg g-1）的污染。此外，还检测到镉、砷、汞、钴、锰、镍、铬、锌和铜。一般线性模型分析表明，红茶样品受污染最严重。用茶叶袋包装的茶叶样本受砷、铝和锰的污染最严重。成人和婴儿的危害指数分别为 0.28 和 1.33，表明对婴儿有不利的非致癌影响。

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.
