英文摘要	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 correlate with the chromite and lignite. Se, Cu, Co and Zn are mainly from geologic origin. The increase of As, Cr, Fe, Hg and Ni in the artificial channel reveals the influence of the soil leaching and groundwater discharge. The high content of Ca2+, Mg2+, Cl-, SO42- and HCO3- in the groundwater is resulted from the arid climate, artificial channel, limestone, dolomite and lignite. Cr, Fe, Ni and Hg in the groundwater primarily derive from the chromite and lignite, and Cd, Mn and Pb may be from the strata. Therefore, the factory synchronously makes the soil metals, EC, salinity and pH increase, and the salinization conversely influences the fate and transport of the metals.
