摘要: 近年,对东北山地丘陵的棕色森林土、黑土地区以及西北黄土高原的环境地球化学与克山病关系的报导较多。这些地区的共同特点是土壤中的腐殖质含量较高,而水溶性硒的含量较低。本文将通过对腐殖质含量极低的高原砂地环境地球化学特点与克山病关系的论述,补充说明低硒环境是克山病的一个重要相关因子。

Abstract: The plateau sandy soil of Keshiketengqi (it is called Keqi for short) is situated in the sheep farm of HaolukuBudengshan.It is a long and narrow regionwhich is 100 km across from east to west and 60 km from north to south.According to previous record,“Keshan Disease”and “KasehimBeck Disease” have occurredmany times in this localitsy the nearer 100 years.These diseases are the immediateharm to the people’s health in body and heart.It is possible that these diseases andthe characteristics of the local environmental geochemistry are closely related,The characteristics of environmental geochemistry in Keqi plateau sandy soilare rich of silicon and poor in many trace elements,particularly the water solubleselenium.The deficiency of water soluble selenium necessarily leads to low seleniumcirculation in soilplantanlmalhuman body system.Water soluble selenium content of grassland soil is around 0.8 ppb;that of cultivated soil is around 0.65 ppbthe average of selenium content in grain and forage grass is around 7 ppb and6 ppb respectively;that in sheep wool is around 25 ppb.The circulation oflow selenium is interrelated with“Keshan Disease”and “White Muscle Disease”in this locality.These circumstances probably are important to the inducement ofsuch diseases in this locality.Through supplying selenium to the residents and domestic animals of thislocality,the selenium level in bodies are raised year by year.Selenium plays animportant role in the prevention and cureness of “Keshan Disease” and “WhiteMuscle Disease”.
