This study was conducted to evaluate the concentration of potentially toxic elements (PTEs) such as arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) in fruit samples collected from Markazi Province, Iran. A probabilistic health risk assessment due to ingestion of PTEs through the consumption of these fruits was also conducted.
The concentration of PTEs in 90 samples of five types of fruits (n = 3) collected from six geographic regions in Markazi Province was measured. The potential health risk was evaluated using a Monte Carlo simulation model.
A significant difference was observed in the concentration of PTEs between fruits as well as soil and water samples collected from different regions in Markazi Province. The order of PTE concentration in the soil and water samples was as follows: Pb > As > Hg > Cd. Furthermore, the highest level of transfer factor for Cd and Hg correlated with the grape. The estimated daily intake for adults and children was lower than the recommended tolerable daily intake.
The population in Markazi Province, Iran, is not at considerable noncarcinogenic or carcinogenic risk due to the ingestion of PTEs through the consumption of the examined fruits.
本研究旨在评估伊朗马赞德兰省采集的水果样本中砷（As）、镉（Cd）、汞（Hg）和铅（Pb）等潜在有毒元素（PTEs）的浓度。还进行了基于摄入这些水果而导致 PTE 摄入的概率性健康风险评估。
测量了马赞德兰省六个地区采集的 90 份五种水果样本（n = 3）中的 PTE 浓度。使用蒙特卡罗模拟模型评估潜在健康风险。
马赞德兰省不同地区采集的水果以及土壤和水样中 PTE 浓度存在显著差异。土壤和水样中 PTE 浓度的顺序为：Pb > As > Hg > Cd。此外，与葡萄相比，Cd 和 Hg 的转移系数最高。成人和儿童的估计日摄入量低于推荐的可耐受日摄入量。
由于摄入了检测到的水果中的 PTEs，伊朗马赞德兰省的人群不存在因摄入 PTEs 而产生的显著非致癌或致癌风险。
