Abstract：In recent years,the issue of polycyclic aromatic hydrocarbons(PAHs)contaminating soils has become increasing-ly severe,with soils serving as the ultimate"sink"for PAHs.The application and development of various remediation tech-nologies have progressed continuously,each with its own advantages and limitations.However,the effectiveness of these remediation processes is often constrained by multiple factors.This review systematically summarizes the applications of four remediation technologies-physical,chemical,biological,and combined remediation-on PAH-contaminated soils of different textures.It provides an in-depth analysis of the advantages and disadvantages of each technology,as well as the impacts of soil texture and environmental factors on degradation efficiency.Among them,microbial remediation and its en-hanced remediation techniques are primary methods to remove PAHs from contaminated soils.Combined remediation can leverage the synergistic effect of each technology to improve the remediation effect of PAH-contaminated soil.Soil texture and physicochemical parameters significantly influence the remediation effectiveness.Optimizing parameters based on soil characteristics and selecting appropriate remediation technologies can promote the development and application of remedia-tion technologies.
