Investigation on Dioxin Level of Flue Gas, Ambient Air, Vegetation and Soil Nearby Large-Scale MSWI in Taiwan

Abstract:

We set up information about Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F) level in flue gas, ambient air, banyan leaves and soil nearby Muzha MSWI, located in the north of Taiwan. Total PCDD/F I-TEQ concentrations in flue gas are 0.0995, 0.0711ng I-TEQ/Nm3, respectively, in spring, autumn, all below the emission limit regulated by Taiwan EPA, 0.1ng I-TEQ/Nm3 . The mean PCDD/F concentrations in ambient air nearby Muzha MSWIs are 0.0283, 0.0357, 0.0391 and 0.05638pg I-TEQ/Nm3, respectively at four seasons. The mean PCDD/F concentrations in banyan leaves nearby are 3.86, 0.873ng I-TEQ/kg, respectively in spring, autumn. The mean PCDD/F concentrations in soil nearby are 1.733, 2.061ng I-TEQ/kg, respectively in spring, autumn, much lower than the emission limit in soil regulated by Taiwan EPA, 1000ng I-TEQ/kg. By comparing the PCDD/F concentration of sample at upwind and downwind sampling sites, the PCDD/F influence from Muzha MSWI on nearby ambient air, vegetation and soil is not obvious.
