Abstract: Selenium(Se) is an important biosis element,and its content in environment directly affects the health and safety of human beings,animals and plants.Based on the latest research advances at home and abroad,this paper set forth the biogeochemical cycling of Se in environment,including the characteristics of Se biogeochemical cycling,the concentration distribution,forms and availability of soil Se,the species distribution of Se in atmosphere and water,and the Se in plant and its absorption.The adjustment of low and high Se in environment and its differentiation cause was discussed,such as parent material type,climate character,weathering and leaching,gaseous volatilization,soil texture,and soil fertility exhaustion.Related hotspot problems and research frontiers of Se in environment were reviewed.
