“…There are many kinds of remediation technologies for POPs-contaminated sites, including gas phase extraction [25,26,27,28,29], soil leaching [30,31,32,33], vitrification [34,35], chemical oxidation [36,37,38,39], incineration method [40,41,42,43], cement kiln co-disposal method [44,45,46,47], thermal desorption [48,49,50], and bioremediation [51,52,53]. The principle is either to increase the usability of contaminated soil through physical and chemical methods, or to degrade the contaminating chemicals through chemical or biological methods.…”
