| 英文摘要 | The prevalence rate of Kaschin-Beck disease (KBD) in most parts of China is currently decreasing, but the disease is still active and severe on the Tibetan Plateau. Soil samples including the surface layer (0-20 cm) and the subsurface layer (20-40 cm) in the cultivated and natural soil profiles were collected, and the mechanical composite and total concentration of arsenic, cobalt, copper, iron, mercury, manganese, molybdenum, selenium, and zinc were determined. Concentrations of arsenic, iron, manganese, copper, and selenium in the surface soil were lower than those in the subsurface soil. The same was true of physical clay in the soil profiles. However, there were no significant differences between the different soil layers. The concentrations of selenium, molybdenum, and mercury were somewhat lower compared with the average concentrations of soils in China. Deficiencies of molybdenum and selenium both play a critical role in occurrence of KBD, but whether or not soil mercury at a low level contributes to KBD is still unclear. A correlation analysis of soil elements showed that there is a positive correlation between iron, cobalt, and manganese due to their similar chemical characteristics. Selenium concentrations in soil as well as the physical clay and iron descend with the deterioration of KBD, but mercury concentrations in soil ascend with the aggravation of the disease. The results show that selenium deficiencies greatly influence the disease, and a deficiency of molybdenum is likely another important factor in inducing KBD. Moreover, determining whether low levels of soil mercury contribute to KBD should be investigated in the future. |
