Remediation Technologies Applied in Polluted Soils:New Perspectives in This Field
There are millions of contaminated areas in the world that need to be remediated so that they can be reused without risk to health.This article presents the main remediation techniques applied to soils,sediments,and groundwater.These technologies can be classified as five processes,i.e.physical,chemical,biological,thermal,and combined.This article also offers a method for choosing the best technique to remediate a place,called sustainable remediation.An evaluation of the toxicity of remediation techniques is presented.Finally,a summary of remediation practice in China is discussed,and the main challenges of future remediation research are presented.The following concluding observations can be reached: the development of a software for the selection of soil remediation technologies can be very helpful to professionals in the field.However,it is important to note that each remediation technology has its own characteristics,limitations,advantages and disadvantages,and no universal method can satisfy all needs.
