摘要
从硒的生物学作用和防治疾病等方面剖析了硒与人体健康的关系 ;从元素地球化学、生物地球化学和化学地理等方面探讨了我国缺硒区的形成、分布和等级的划分 ;从环境地球化学物质场和元素生物地球化学营养链等方面 ,阐明了作物、禽畜和人体缺硒的原因、危害及其人体补硒的途径和方法 ,提出了在缺硒区运用元素生物地球化学营养链营养结构模式的原理、和技术方法 ,从土壤中获取富硒有机食品 ,供居民食用 ,是进行食物补硒、提高人体摄硒量。
This article analyzes the relationship between selenium and Human's health from the aspect of biological function of selenium ,the prevention of diseases and etc. It discusses,from the aspect of element geochemistry, biological geochemistry and chemical geography, the formation of the selenium -shortage areas, their distribution, and grades.From the aspects of environmental chemistry and the element biological chemistry nutrition chain, it states the reason and cause of lack of selenium around the agricultural products, livestock, domestic birds and humans and gives the approaches and methodology of obtaining selenium, meanwhile it is the essential measure of acquiring rich-selenium organic food from the soil by using the theory, technique and methods of the element biological geochemistry nutritious chain and nutrition circulation structural formats for people to improve the immune systems.
