Abstract

Background

The health risk of Se has gained significant attention. Previous studies mainly focused on the health risk of total Se in high-Se area. Less attention has been paid to the health risk of organic selenium in areas with varying selenium levels.

Methods

A total number of 109 crop samples (edible parts) were collected in Langao County, Shannxi Province, China from 2018 to 2020, including 42 corn, 18 rice, 9 sweet potato, 25 potato, 12 radish, and 3 eggplant samples. The hydride generation atomic fluorescence spectrometry (HG-AFS) method was used to determine the total and organic Se contents.

Result and conclusion

(1) Corn (2.82 mg/kg), rice (0.44 mg/kg), potato (6.56 mg/kg), and eggplant (0.77 mg/kg) in high-Se area, as well as sweet potato (1.07 mg/kg) and radish (4.28 mg/kg) in medium-Se area, exhibited the highest total Se content among all crops in this county, and 5–328 times higher than the values of Se-enriched standard (2) The average daily intake of total/organic Se of residents in high-Se area reached 676/449 μg/day, which was 1–4 times higher than levels observed in medium-Se area (419/257 μg/day) and low-Se area (196/128 μg/day). The organic Se daily intakes from dietary combinations of rice + radish and rice + eggplant in high-Se area lower than 400 μg/day, which could be safely consumed. The organic Se daily intakes from dietary combinations of sweet potato + radish and sweet + eggplant in medium-Se area higher than 400 μg/day, which could not be safely consumed. The total / organic Se daily intakes of all dietary combinations in low-Se area lower than 400 μg/day, which could be safely consumed. (3) The health risk associated with crops might be overestimated due to the higher non-carcinogenic risk attributed to total Se compared to organic Se. The present study demonstrated that daily intake and health risk of total and organic Se in crops across areas with different Se levels varied significantly.

不同硒水平地区农作物总硒和有机硒的估计日摄入量和健康风险评估

背景 Se 对健康的危害已引起人们的极大关注。以往的研究主要集中在高硒地区总硒的健康风险上。方法2018-2020年在陕西省岚皋县共采集农作物样品（可食部分）109份，其中玉米42份、水稻18份、甘薯9份、马铃薯25份、萝卜12份、茄子3份。结果与结论（1）高Se区玉米（2.82 mg/kg）、水稻（0.44 mg/kg）、马铃薯（6.56 mg/kg）、茄子（0.77 mg/kg），中Se区红薯（1.07 mg/kg）、萝卜（4.高Se地区居民日均总/有机Se摄入量达676/449微克/天，是中Se地区（419/257微克/天）和低Se地区（196/128微克/天）的1-4倍。在高Se地区，大米+萝卜和大米+茄子膳食组合的有机硒日摄入量低于400微克/天，可以放心食用。中Se地区红薯+萝卜和红薯+茄子膳食组合的有机Se日摄入量高于400微克/天，不能安全食用。低Se地区所有膳食组合的总Se/有机Se日摄入量低于400微克/天，可以安全食用。(3）与农作物相关的健康风险可能被高估，因为与有机硒相比，总硒的非致癌风险更高。本研究表明，在不同硒水平的地区，农作物中总硒和有机硒的日摄入量和健康风险存在显著差异。

期刊介绍： The journal provides the reader with a thorough description of theoretical and applied aspects of trace elements in medicine and biology and is devoted to the advancement of scientific knowledge about trace elements and trace element species. Trace elements play essential roles in the maintenance of physiological processes. During the last decades there has been a great deal of scientific investigation about the function and binding of trace elements. The Journal of Trace Elements in Medicine and Biology focuses on the description and dissemination of scientific results concerning the role of trace elements with respect to their mode of action in health and disease and nutritional importance. Progress in the knowledge of the biological role of trace elements depends, however, on advances in trace elements chemistry. Thus the Journal of Trace Elements in Medicine and Biology will include only those papers that base their results on proven analytical methods. Also, we only publish those articles in which the quality assurance regarding the execution of experiments and achievement of results is guaranteed.
