| Popis: | 93 The mean PCDD/Fs concentration in 8 ambient air samples in the vicinity of PI municipal solid waste incinerator (MSWI) is 0.069 pg-I-TEQ/Nm3. Compared with ambient air concentration of Japan regulation level (0.6 pg-I-TEQ/Nm3), the ambient air concentration of the PI incinerator is lower than Japanese regulation level. The mean PCDD/Fs composition in vegetation and soil samples in the vicinity of PI MSWI is 2.259 and 1.007 ng-I-TEQ/kg-d.w., respectively. In this study, even the soil from site C, which has the highest PCDD/Fs level, can still be freely utilized (based on the German regulation value). According to the homologue profile of ambient air samples, most sites had profiles similar to those of PI MSWI or mobile sources. By comparing the PCDD/Fs concentration (composition) of maximum ground concentration sampling sites, upwind and downwind sampling sites, it is concluded that the emission of PCDD/Fs from the PI MSWI to its surrounding environment is not significant. |
