PCDD/Fs (polychlorinated dibenzo-p-dioxins and dibenzofurans) have been extensively studied for many years owing to their acute toxicity and associated adverse health effects, since they had been found in the stack flue gas and fly ash of municipal solid waste incinerators (MSWIs) [Olie et al., 1977]. In the ambient air, researches associated PCDD/Fs and their subtopics had been reported in different countries [Shih et al., 2006; Raun et al., 2005; Im et al., 2004]. However, little of them were aimed at characterizing the differences of PCDD/F emissions among different type of environments. This study selected one industrialized area and two areas near the municipal solid waste incineration plants, primarily attempted to compare the PCDD/F concentrations in the ambient air of different area. Then, the effect of biomass combustion on the PCDD/F concentration in the ambient air was evaluated.
