In order to find out the environmental geochemical characteristics of KBD affected area, KBD and non-KBD villages in KBD Counties, Weibei KBD area, Shaanxi Province, China were studied. Contents of Se and other elements in soil, wheat, maize and drinking water were analyzed. The results show that soil of Weibei KBD area is deficient in trace elements comparing with BSC and non-KBD area. Wheat of Weibei KBD area is deficient both in major elements and trace elements comparing with REC. Wheat of KBD village is especially deficient in Cr, Co, Se, Mo and Mg. Contents of Sr, Li and Mo in wheat of KBD village are significantly lower than nearby non-KBD village, but the average Se content is slightly higher. The deficiency of trace elements, especially Se, Sr, Li and Mo in staple food and trace elements in soil, is the main characteristic for the environment of KBD area.
为了查明克山病（KBD）病区、病村与非病区、非病村环境地球化学特征，对陕西省渭北 KBD 地区的病村、病区及非病村进行了调查，分析了土壤、粮食（小麦、玉米）、饮水等环境介质中硒及其他元素的含量。结果表明，渭北 KBD 地区土壤与 BSC 和非病区比较，微量元素亏缺。渭北 KBD 地区粮食作物中常量元素和微量元素均亏缺，与 REC 比较，小麦中 Cr、Co、Se、Mo、Mg 等元素亏缺严重。KBD 村小麦中 Sr、Li、Mo 含量显著低于临近非病村，而平均 Se 含量稍高。主食微量元素，尤其是 Se、Sr、Li、Mo 亏缺，土壤微量元素亏缺是病区环境的主要特征。
