The contents of selenium in soil samples from Guizhou Province, which cover an area of 17.6×104 km2, have been determined. The arithmetic mean value of 947 samples is 0.39 mg/kg, the medium value is 0.30 mg/kg and the contents of selenium vary from 0.06 to 1.29 mg/kg in soils developed on the basement rocks, which are controlled by the basement rocks themselves.
