Lead (Pb), cadmium (Cd), arsenic (As), chromium (Cr), and nickel (Ni) are poisonous, widely distributed, persistent, and transferable to crops, posing potential health risks. This study aims to assess the potential health risks of those elements in rice collected from North-Central Vietnam: Thanh Hoa, Nghe An, and Ha Tinh provinces. Element analysis was performed on rice harvested in November 2020 by ICP-MS. The estimated daily intake (EDI), target hazard quotient (THQ), non-carcinogenic hazard index (HI), and target carcinogenic risk (TR) were used to assess potential health risks for different population groups. The highest element levels (mg kg dry weight) were observed for Cr (0.30 ± 0.11), As (0.17 ± 0.025) and for Pb (0.24 ± 0.013) in Thanh Hoa, and for Cd (0.088 ± 0.015) in Ha Tinh. Strong links were observed between geological formations, mining activities and Cr in rice (Thanh Hoa), or industrial activities and Ni accumulation in rice (Hung Nguyen and Ky Anh districts). Children had greater EDIs than adults, with As having a higher EDI than RfD. Rice THQs indicated a risk trend: Thanh Hoa > Ha Tinh > Nghe An, with As being a significant contributor to HIs. Cr and Cd were significant risk factors and HIs in female children were 1.5 times higher than in other groups. Based on TR values for Ni and Pb, a potential carcinogenic risk to rice eaters was observed, particularly Ni. The data revealed a significant human health risk (both non-carcinogenic and carcinogenic) connected with rice consumption. Therefore, crops and foods from North-Central Vietnam should be strictly regulated.
铅(Pb)、镉(Cd)、砷(As)、铬(Cr)和镍(Ni)是有毒的,广泛分布,持久存在且可转移到农作物中,对健康构成潜在风险。本研究旨在评估越南北中部清化省、义安省和河静省采集的大米中这些元素的潜在健康风险。2020 年 11 月,采用 ICP-MS 对收获的大米进行元素分析。采用估计日摄入量(EDI)、目标危害系数(THQ)、非致癌危害指数(HI)和目标致癌风险(TR)评估不同人群的潜在健康风险。Cr(0.30±0.11)、As(0.17±0.025)和 Pb(0.24±0.013)的元素水平最高的是清化省,Cd(0.088±0.015)的元素水平最高的是河静省。在清化,地质构造、采矿活动与 Cr 之间存在很强的联系,或者在Hung Nguyen 和 Ky Anh 区,工业活动与 Ni 在大米中的积累之间存在很强的联系。儿童的 EDI 大于成人,As 的 EDI 高于 RfD。大米 THQ 表明存在风险趋势:清化>河静>义安,As 是 HI 的重要贡献者。Cr 和 Cd 是显著的风险因素,女童的 HI 比其他组高 1.5 倍。基于 Ni 和 Pb 的 TR 值,观察到食用大米的潜在致癌风险,尤其是 Ni。数据显示,与食用大米有关的健康风险(包括非致癌和致癌风险)很大。因此,越南北中部的作物和食品应受到严格监管。
