    Abstract: This study focuses on the atmospheric dry deposition flux of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in the vicinity of the two municipal solid waste incinerators (MSWIs) located in southern Taiwan. PCDD/Fs in ambient air were taken and analyzed for seventeen 2,3,7,8-substituted PCDD/Fs during November 2004 and July 2005. Results show that the mean concentrations of PCDD/Fs in the ambient air near MSWI-GS and MSWI-GS were 0.090 and 0.097 pg I-TEQ/Nm3, respectively. Dry
    deposition fluxes of total PCDD/Fs were 18.0 and 23.5 pg I-TEQ/(m2 d) in the ambient air near MSWIGS and MSWI-GS, respectively, which were considerably higher than that measured in Guangzhou, China. Annual dry deposition fluxes of total PCDD/Fs in the ambient air near MSWI-GS and MSWIRW were 189 and 217 ng/(m2 year), respectively, which were also much higher than dry deposition of
    total PCDD/Fs to the Atlantic Ocean. The results of the present study strongly suggest that exposure to PCDD/Fs in this area should be reduced. In addition, parametric sensitivity shows that dry deposition flux of PCDD/Fs is most sensitive to dry deposition velocity of the particle-phase, followed by air temperature
    and concentration of total suspended particulate but least sensitive to dry deposition velocity of the gas-phase.
