The mean PCDD/F concentration in ambient air nearby Wooz municipal solid waste incinerator (MSWIs) is 0.142 pg I-TEQ/Nm3. The mean PCDD/F content in Ficus leaves nearby this MSWI is 5.07 ng I-TEQ/kg. The mean PCDD/F content in soil nearby this MSWI is 1.60 ng I-TEQ/kg. By comparing the PCDD/F concentration of maximum ground concentration sampling sites, upwind sampling sites and downwind sampling sites, the distribution of the PCDD/F concentration isopleths in the atmosphere and the result of PCA, the PCDD/F influence from MSWI on nearby ambient air, vegetation and soil is not obvious, however, some sampling sites which are around by other stationary emission sources or mobile source are found with elevated PCDD/F level. From the above result, the influence of PCDD/F emission from Wooz MSWI on surrounding environment is not obvious.
