Abstract: The data of Cr and As in the sampls of agricultural purplish soils and yellow earth assume formal distribution. Differences of Cr content were signific cant while a nhose of As were not, However, the contents of Cr and As varied in different parent materials. The different data would be arranged in the following order; shale purplish soil> sandstone purplish soil; flood deposit yellow earth> lime concretion yellow earth> old fluviogenie yellow earth. Heavier soil texture caused greater content levels of Cr aud As. The contents of Cr and As in the surface horione and sudsoil were almost in the same amounts. The variable range of background values would be expressed as x ±2δ.
