The paper discusses current mechanistic theories relating to the formation of polychlorinated dibenzodioxin and polychlorinated dibenzofuran (PCDD/F) and how these theories relate to coal combustion, diesel vehicles, and open burning practices that may be of interest for the Asia-Pacific region. Co-firing coal with waste combustion has been shown to significantly decrease PCDD/F formation, likley by affecting the catalytic activity of the fly ash. On-road sampling results for diesel trucks have shown that modern, electronically controlled vehicles are likely a minor source of PCDD/F, although older vehicles remain a virtually uncharacterized and potentially significant source. Recent results from open burning of municipal waste have shown that PCDD/F emission factors are at least 14 orders of magnitude higher than modern waste combustors.
