摘要 通过对(?)施花被高硒地区近50种样品分析表明,各种样品硒含量明显高于对照地区的同类样品,以玉米、黄豆、叶类蔬菜含硒量较高。高硒石煤的风化、雨淋,尤其是人们的开采和使用是造成环境富硒的主要因素。植物硒通过富硒土壤而富集,从而进入人们的食物链。 Enshi district was first recognized as se-leniferous area in china,where selenosis out-break among humans and animals once oc-curred.In order to determine the effects of en-vironmental selenium on the food chain,an in-vestigation has been carried out in selenium-rich area and non-seleniferous area with no se-lenosis history.Analysis of over 50 sampleshave demostrated that the selenium content infoods in seleniferous area was remarkabletyhigher than that in non-seleniferous area(p<0.01),but with wide variance,showing a sig-nificant correlation between the environmentalselenium and foods.The stony coal had high-est selenium content in environment,amongfoods selenium level in maize,soy-bean andgreen vegetables stood high.This area hastherefore been classified as se-excessive eco-logical landscape.Se was brought to environ-ment mainly through excavation and utiliza-tion,weathering and rain-drenching of selenif-erous stony coal,and was thus accumulationand enriched in plant foods,and was thentransferred the food chain for human con-sumption.Keshan Diseases and Kaschin-Beokdisease have been identified in 15 provincesand districts,development of Se-rich foods inseleniferous area and supply of these foodproducts to Se-poor areas might be helpful inthe control of these diseases.
