| Abstract: | The horizontal and verticle distribution of various forms of selenium in Dianshan Lake sediment have been studied. Discussion on natural environmental factors and distribution characteristics of selenium species in sediment were presented. It was found that they were mainly in the forms of element, organic and sulfide bounded, which accounted for 33%-57% of total selenium. The distribution of selenium species was related to the environmental factors. |
