This paper gives introduction of structure,property and hazard of dioxins and of the generation route,mechanisms of PCDD/Fs formation including heterogeneous catalytic synthesis from precursors and De novo synthesis and main influening factors on formation of PCDD/Fs in municipal solid waste incineration.

A mixed culture of Acidihiobacillus ferrooxidans and Acidihiobacillus thiooxidans was used to leach heavy metals from MSWI fly ash (municipal solid waste incineration fly ash) to render them nonhazardous.
