Abstract

Highlights: We assessed concentrations of Se and other elements in KBD area and KBD village. Low concentrations of Mo, Se, U, Rb and Cs were found in soil of KBD area. Low concentrations of most trace elements including Se were found in wheat of KBD area. Low concentrations of Sr, Li and Mo were found in wheat of KBD village. Deficiencies of minerals in staple food is the main environmental characteristic of KBD area. Abstract: 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.
