The rice contamination to heavy metals and its associated health risks have been less addressed in the southeast of Iran. In the present study, in the mentioned region, we assessed the concentration of nine elements in rice, and the health risk related to the measured elements was determined using the data which were gathered by a questionnaire. For this purpose, 36 samples of the 12 most widely consumed rice brands were collected. Using ICP-MS, the concentrations of Ni, Cr, Hg, Sr, Mn, Fe, Se, Ba, and Zn were measured in the studied samples as 0.599 ± 0.124, 0.483 ± 0.28, 0.0157 ± 0.005, 0.85 ± 1.307, 11.5 ± 1.97, 178.46 ± 67.27, 0.212 ± 0.083, 0.845 ± 0.62, and 8.416 ± 1.611 mg/kg, respectively. We found that, regarding the other studies, the levels of Ni, Cr, Hg, Fe, and Ba were higher. Besides, using 258 distributed questionnaires among citizens, the daily rice consumption was determined to be 295.66 ± 171.005 g/person/ day. Based on this consumption rate and Monto Carlo uncertainty simulation, Fe (0.741 ± 0.54 mg/kg/day) and Se (8.95E-04 ± 6.33E-04 mg/kg/day) showed the highest and lowest daily intake, respectively. Also, using Hazard Quotient (HQ), the non-carcinogenic risk effects of the surveyed elements were estimated. The obtained results of HQ revealed that Fe (2.48) and Mn (1.06) could pose non-carcinogenic health risks to consumers. Moreover, the calculated hazard Index showed that the overall health risk of the surveyed elements is in an unsafe range.

在伊朗东南部，大米对重金属的污染及其相关的健康风险很少得到解决。在本研究中，在上述地区，我们评估了大米中九种元素的浓度，并使用问卷收集的数据确定了与测量元素相关的健康风险。为此，收集了 12 个消费最广泛的大米品牌的 36 个样本。使用 ICP-MS，所研究样品中 Ni、Cr、Hg、Sr、Mn、Fe、Se、Ba 和 Zn 的浓度为 0.599 ± 0.124、0.483 ± 0.28、0.0157 ± 0.005、0.85 ± 1.305、11分别为 ± 1.97、178.46 ± 67.27、0.212 ± 0.083、0.845 ± 0.62 和 8.416 ± 1.611 毫克/千克。我们发现，对于其他研究，Ni、Cr、Hg、Fe 和 Ba 的含量更高。除了，使用258份分发的公民问卷，确定每日大米消费量为295.66±171.005克/人/天。根据这一消耗率和 Monto Carlo 不确定性模拟，Fe (0.741 ± 0.54 mg/kg/day) 和 Se (8.95E-04 ± 6.33E-04 mg/kg/day) 分别显示出最高和最低的每日摄入量。此外，使用危险商数 (HQ)，估计了调查元素的非致癌风险影响。HQ 获得的结果表明，Fe (2.48) 和 Mn (1.06) 可能对消费者构成非致癌健康风险。而且，计算的危害指数表明，被调查元素的整体健康风险处于不安全范围内。54 毫克/公斤/天）和硒（8.95E-04 ± 6.33E-04 毫克/公斤/天）分别显示最高和最低的每日摄入量。此外，使用危险商数 (HQ)，估计了调查元素的非致癌风险影响。HQ 获得的结果表明，Fe (2.48) 和 Mn (1.06) 可能对消费者构成非致癌健康风险。而且，计算的危害指数表明，被调查元素的整体健康风险处于不安全范围内。54 毫克/公斤/天）和硒（8.95E-04 ± 6.33E-04 毫克/公斤/天）分别显示最高和最低的每日摄入量。此外，使用危险商数 (HQ)，估计了调查元素的非致癌风险影响。HQ 获得的结果表明，Fe (2.48) 和 Mn (1.06) 可能对消费者构成非致癌健康风险。而且，计算的危害指数表明，被调查元素的整体健康风险处于不安全范围内。
