Considering the chromium (salt) industrial wasteland, the area of chromium鄄con鄄 taminated soil caused by the accumulation of chromium slag has reached 5 million square meters, and its direct utilization can result in health hazards to the public and threaten the environment. Therefore, it is of great practical significance to carry out research on eco鄄 nomic, efficient, and clean methods for chromium鄄contaminated soil remediation. In this paper, the origin and occurrence of the chro鄄 mium in soil, their extraction methods, and the research progress of chromium鄄contaminated soil in and outside China were reviewed. First, the occurrence of the chromium in soil was discussed. It is found that Cr exists predominantly in Cr(芋) and Cr(遇) oxidation states, whereby Cr(芋) is the more stable; under most prevailing environmental conditions Cr(遇) is rapidly reduced to Cr(芋). The methods of extracting chromium from soil were presented, including Tessier sequential extraction procedure and the European Commu鄄 nity Bureau of Reference(BCR) three鄄step sequential extraction procedure, and then the two continuous extraction methods were com鄄 pared and evaluated. Afterward, the remediation techniques of chromium鄄contaminated soil were systematically reviewed, including en鄄 gineering physical repair methods, dilution methods, immobilization and stabilization, chemical reduction, electrokinetics repair, and bioremediation. The advantages and disadvantages of the various remediation techniques were compared, summarized, and evaluated. The developments of chromium鄄contaminated soil remediation technologies in the future were also explored, including the clean remedi鄄 ation technologies, combination of several remediation technologies, and novel nano鄄remediation materials. Accordingly, suggestions for the remediation of different chromium鄄contaminated soils were presented, which can provide references for clean and efficient reme鄄 diation of chromium鄄contaminated soils
