Abstract:		"Soil pollution has become a global environmental concern. Thermal desorption is one of the methods commonly used to remediate contaminated soil. This method has received increasing attention for remediating contaminated sites due to its advantages, such as suitability to different types of contaminants, short treatment period, high efficiency, high safety, and capability to recycle soil and contaminants. This paper provides a comprehensive review of studies on thermal desorption. Introduction of the mechanism, classification, and cost of thermal desorption is presented. Factors affecting the performance of thermal desorption (heating temperature, heating time, heating rate, carrier gas, soil particle size, moisture content, initial concentration of contaminants, and additives) are reviewed. Thermal desorption produces off-gases, which are mostly organic compounds and may result in secondary pollution. Thus far, treatment methods for off-gas have not been systematically investigated. This paper also summarizes current methods for treatment of off-gas in the soil field and of volatile organic compounds in atmospheric and water pollution fields. Several feasible off-gas treatment methods are also comparatively analyzed, and the corresponding principles, advantages, disadvantages, and application ranges are discussed"
