摘　　要：The research progress on the mechanisms of formation and degradation of polychlorinated dibenzo-p-dioxins ( PCDDs ) and dibenzofurans ( PCDFs ) is reviewed. The primary sources of PCDD/Fs are chemical, thermal, photochemical and enzymatic reactions. Most of the thermal sources result in emissions into air. The studies on the photodegradation and biodegradation offer promise for destruction of PCDD/Fs in environment.The research progress on the mechanisms of formation and degradation of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) is reviewed.
