The intake of trace elements (TEs) through the consumption of vegetables is a subject of great concern. This study intends to evaluate human health risks associated with consumption of vegetables grown near the Ventanas copper smelter (Valparaiso region, Central Chile). Experimental plots were established in the proximity of the smelter and in a control area. Leafy vegetables (lettuce, chard, and cabbage) and root vegetables (potato, carrot, and beetroot) were grown on the experimental plots. Daily intake of elements was estimated based on consumption habits. A hazard quotient (HQ) was calculated as a ratio between the daily intake and the reference dose that represents the maximum safe TE intake. Generally, concentrations of TEs in the edible tissues of vegetables were higher in the exposure area than in the control area. The most significant difference was for leafy vegetables, with arsenic (As) being the main TE of concern. Lettuce was also the vegetable of concern due to its relatively high consumption rate and a relatively high concentration of TEs in the plant tissue. In this study, we obtained an HQ value of ~ 0.6 for inorganic As considering vegetable consumption pathway, for the age group of 1–5 years old. Likewise, our previous study reported a similar HQ value of ~ 0.6 for inorganic As considering incidental soil and dust ingestion pathway, for the same age group. Importantly, HQ value surpasses 1.0 for inorganic As considering both exposure pathways. Thus, there is a health risk associated with soil As for inhabitants of Puchuncavi Valley.

食用智利中部铜冶炼厂附近种植的蔬菜的人类健康风险评估

通过食用蔬菜摄入微量元素 (TE) 是一个备受关注的问题。本研究旨在评估与食用在 Ventanas 铜冶炼厂(瓦尔帕莱索地区,智利中部)附近种植的蔬菜有关的人类健康风险。在冶炼厂附近和控制区建立了试验区。叶类蔬菜(生菜、甜菜和卷心菜)和块根类蔬菜(马铃薯、胡萝卜和甜菜根)种植在试验地块上。元素的每日摄入量是根据消费习惯估算的。风险商 (HQ) 计算为每日摄入量与代表最大安全 TE 摄入量的参考剂量之间的比率。一般来说,暴露区蔬菜可食用组织中TEs的浓度高于对照区。最显着的差异是叶类蔬菜,砷 (As) 是主要关注的 TE。生菜也是值得关注的蔬菜,因为其消耗率相对较高,并且植物组织中的 TE 浓度相对较高。在本研究中,考虑到蔬菜消费途径,对于 1-5 岁年龄段的无机 As,我们获得了约 0.6 的 HQ 值。同样,我们之前的研究报告了相同年龄组的无机 As 的类似 HQ 值约为 0.6,考虑到偶然的土壤和灰尘摄入途径。重要的是,考虑到两种暴露途径,无机 As 的 HQ 值超过 1.0。因此,对于普春卡维山谷的居民而言,土壤存在健康风险。生菜也是值得关注的蔬菜,因为其消耗率相对较高,并且植物组织中的 TE 浓度相对较高。在本研究中,考虑到蔬菜消费途径,对于 1-5 岁年龄段的无机 As,我们获得了约 0.6 的 HQ 值。同样,我们之前的研究报告了相同年龄组的无机 As 的类似 HQ 值约为 0.6,考虑到偶然的土壤和灰尘摄入途径。重要的是,考虑到两种暴露途径,无机 As 的 HQ 值超过 1.0。因此,对于普春卡维山谷的居民而言,土壤存在健康风险。生菜也是值得关注的蔬菜,因为其消耗率相对较高,并且植物组织中的 TE 浓度相对较高。在本研究中,考虑到蔬菜消费途径,对于 1-5 岁年龄段的无机 As,我们获得了约 0.6 的 HQ 值。同样,我们之前的研究报告了相同年龄组的无机 As 的类似 HQ 值约为 0.6,考虑到偶然的土壤和灰尘摄入途径。重要的是,考虑到两种暴露途径,无机 As 的 HQ 值超过 1.0。因此,对于普春卡维山谷的居民而言,土壤存在健康风险。1-5岁年龄段。同样,我们之前的研究报告了相同年龄组的无机 As 的类似 HQ 值约为 0.6,考虑到偶然的土壤和灰尘摄入途径。重要的是,考虑到两种暴露途径,无机 As 的 HQ 值超过 1.0。因此,对于普春卡维山谷的居民而言,土壤存在健康风险。1-5岁年龄段。同样,我们之前的研究报告了相同年龄组的无机 As 的类似 HQ 值约为 0.6,考虑到偶然的土壤和灰尘摄入途径。重要的是,考虑到两种暴露途径,无机 As 的 HQ 值超过 1.0。因此,对于普春卡维山谷的居民而言,土壤存在健康风险。
