On Standards of Selenium Enriched Agricultural Products and Selenium-rich Soil in China

硒是人和动物生命活动必需的微量元素,缺硒可影响人体健康并导致诸多疾病。通过富硒农产品补硒是一种简单而有效的方法。本文从硒对人体的健康功效、居民硒的摄入量状况、土壤硒分布与作物硒吸收特征、富硒土壤研究现状、富硒农产品标准、富硒农产品中硒摄入量安全性评估等方面,进行了系统研究,阐述了研制富硒土壤分类标准的必要性。

Selenium (Se)is an essential trace element for humans and animals.Selenium deficiency can affect human health and lead to many diseases.It is a simple and effective way to supplement Se by eating Se enriched agricultural products. This paper systematically studied the effects of Se on human health,the daily Se intake by residents,the distribution of Se in soil and the characteristics of Se uptake by crops,the researches of Se-rich soils,the standards of Se-enriched agricultural products, and the safety assessment of Se intake from Se-enriched agricultural products.The necessity of developing the classification standard of selenium-rich soil was also described in this paper.
