Geochemical characteristics of selenium-rich soil in Beibu Gulf coastal economic zone of Guangxi
摘要
Abstract
Based on geochemical investigation of soil in the study area, the authors studied characteristics of selenium distribution, sources and physical⁃chemical properties of soil in the Beibu Gulf coastal economic zone of Guangxi. The results show that the total se⁃lenium content in surface soil is from 0.06×10-6 to 0.90×10-6, with the average value of 0.44×10-6. The total selenium content in deep soil is from 0.07×10-6 to 0.92×10-6, with the average value of 0.44×10-6. The total selenium content in the surface soil to a certain ex⁃tent has inherited the selenium from the parent materials. The correlation analysis indicates that the total selenium content in soil has a significant positive correlation with carbon, organic carbon, aluminum oxide and total iron oxide, indicating that organic carbon, iron and manganese oxides in the soil and the weathering and leaching extent play important roles in the geochemical behaviors of selenium. The ecological quality of the study area is excellent with the potential of developing selenium⁃rich agricultural products.关键词
