Pistachio is an important horticultural product and Iran is considered as a main pistachio producing country. Assessment of heavy metals in this export fruit is crucial for protecting public health against toxic heavy metals. The concentration of selected heavy metals in soil, water and five pistachio cultivars from four geographical regions of Iran were measured. Although none of the elements were detected in water irrigation, infield metal content in the soil had good correlation with that of pistachio. The highest amounts of Al, As, Co, Ni and Se were reported in samples collected from Sarakhs, Iran. Considering both cultivar and region effects on selected heavy metals concentration, Kaleghoochi cultivar from Sarakhs site showed the highest amount of Al, As, Ni and Se. The maximum concentration of Hg was found in Akbari cultivar collected from Damghan. In the Akbari and the Ahmad aghaei cultivars collected from Sarakhs and Damghan cultivation zones, respectively, the highest amount of Co were observed. Based on our results, the HI value for the consumers of Iranian pistachio was 0.066. It seems that the levels of heavy metals in these pistachio samples pose no risk to consumers.
开心果是一种重要的园艺产品，伊朗被视为主要的开心果生产国。评估这种出口水果中的重金属对于保护公众健康免受有毒重金属侵害至关重要。测定了伊朗四个地理区域土壤、水以及五个开心果品种中选定重金属的浓度。虽然在灌溉水中未检测到任何元素，但土壤中的田间金属含量与开心果中的金属含量具有良好的相关性。在从伊朗萨拉赫斯采集的样本中，铝、砷、钴、镍和硒的含量最高。考虑到品种和区域对选定重金属浓度的影响，来自萨拉赫斯地区的卡莱古奇品种的铝、砷、镍和硒含量最高。在从达姆甘采集的阿克巴里品种中发现汞的最高浓度。分别在从萨拉赫斯和达姆甘种植区采集的阿克巴里品种和艾哈迈德·阿加伊品种中，观察到钴的含量最高。根据我们的结果，伊朗开心果消费者的健康指数值为0.066。这些开心果样本中的重金属含量似乎对消费者没有风险。
