To understand the origin of metals in the topsoil, surface and ground water in arid area, field investigation and statistics were used in a chromium contaminated site in northwest China. The strong positive correlations among the soil EC, salinity and pH are attributed to the extensive evaporation and leaching of the chromite, lignite, limestone and dolomite. The scarce precipitation is responsible for the accumulation of metals in the topsoil. The soil salinization influences the metal mobility. Cr, Fe, Ni, As, Hg, V and Sb in the topsoil corr...
