In the recent years, there has been a growing interest in monitoring heavy metal contamination of spices/herbs. Spices and herbs are sources of many bioactive compounds that can improve the tastes of food as well as influence digestion and metabolism processes. In the present study, the levels of some essential and toxic elements such as iron (Fe), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), lead (Pb), and cadmium (Cd), present in common spices/herbs that were purchased from the local market in Saudi Arabia, were analyzed by atomic absorption spectroscopy after digestion with nitric acid/hydrogen peroxide mixture. Samples from the following spices/herbs were used: turmeric, cloves, black pepper, red pepper, cumin, legume, cinnamon, abazir, white pepper, ginger, and coriander. The concentration ranges for the studied elements were found as 48.8-231, 4.7-19.4, 2.5-10.5, below detection level (BDL)-1.0, 8.8-490, 1.0-2.6, and BDL-3.7 µg g(-1) for Fe, Zn, Cu, Cr, Mn, Ni, and Pb, respectively, while Cd and Co levels were below the detection limit. Consumers of these spices/herbs would not be exposed to any risk associated with the daily intake of 10 g of spices per day as far as metals Fe, Zn, Cu, Cr, Mn, Ni, and Pb are concerned.
近年来，人们对监测香料/草本植物中的重金属污染越来越感兴趣。香料和草本植物是许多生物活性化合物的来源，这些化合物可以改善食物的味道，并影响消化和新陈代谢过程。在本研究中，采用硝酸/过氧化氢混合液消解后，用原子吸收光谱法分析了从沙特阿拉伯当地市场购买的常见香料/草本植物中一些必需元素和有毒元素的含量，如铁（Fe）、锌（Zn）、铜（Cu）、铬（Cr）、锰（Mn）、钴（Co）、镍（Ni）、铅（Pb）和镉（Cd）。使用了以下香料/草本植物的样品：姜黄、丁香、黑胡椒、红辣椒、孜然、豆类、肉桂、阿巴齐尔、白胡椒、姜和香菜。研究发现，所研究元素的浓度范围分别为：铁48.8 - 231、锌4.7 - 19.4、铜2.5 - 10.5、铬低于检测限（BDL）- 1.0、锰8.8 - 490、镍1.0 - 2.6、铅BDL - 3.7 μg g(-1)，而镉和钴的含量低于检测限。就铁、锌、铜、铬、锰、镍和铅等金属而言，这些香料/草本植物的消费者每天摄入10克香料不会面临任何与之相关的风险。
