Title 大型垃圾焚化廠周界空氣、植物及土壤中戴奧辛含量調查計畫
Abstract 基隆廠大氣、植物及土壤PCDD/Fs總I-TEQ平均濃度分別為0.0293 pg I-TEQ/Nm3、1.34與0.875 ng I-TEQ/kg。藉由四季大氣PCDD/Fs濃度之等位軌跡圖顯示，位於基隆廠上、下風處採樣點其濃度變化與風瑰圖並無明顯關係。由上可知顯示基隆廠試運轉階段對周界環境PCDD/Fs之影響並不顯著。利澤廠大氣、植物及土壤PCDD/Fs總I-TEQ濃度平均濃度分別為0.0649 pg I-TEQ/Nm3、1.75 與0.779 ng I-TEQ/kg。藉由四季周界大氣採樣點所得濃度之等位軌跡圖與風瑰圖顯示，由於各季盛行風向不同，但大氣PCDD/Fs高濃度之分佈一致，可知利澤廠試運轉階段對周界大氣PCDD/Fs之影響並不顯著。岡山廠大氣、植物及土壤PCDD/Fs總I-TEQ平均濃度分別為0.0792 pg I-TEQ/Nm3、3.91 與1.67 ng I-TEQ/kg。崁頂廠大氣、植物及土壤PCDD/Fs總I-TEQ平均濃度分別為0.0630 pg I-TEQ/Nm3、2.07 與0.988 ng I-TEQ/kg。將焚化廠各採樣點周界大氣與岡山廠、崁頂廠及其他固定污染源及移動污染源煙道廢氣PCDD/Fs特徵剖面進行主要成分分析，結果顯示周界大氣PCDD/Fs與各焚化廠無明顯關聯性。
EngTitle Investigation on dioxin level of ambient air, vegetation and soil nearby large-scale municipal solid waste incinerators
EngAbstract The mean PCDD/F concentrations in ambient air nearby Keelung, Lize, Gangshan and Kanding municipal solid waste incinerators (MSWIs) are 0.0293, 0.0649, 0.0792 and 0.0630 pg I-TEQ/Nm3, respectively. The mean PCDD/F contents in Ficus leaves nearby these three MSWIs are 1.34, 1.75, 3.91 and 2.07 pg I-TEQ/g, respectively. The mean PCDD/F contents in soil nearby these three MSWIs are 0.875, 0.779, 1.67 and 0.988 pg I-TEQ/g, respectively. 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 MSWIs on nearby ambient air, vegetation and soil is not obvious, however, some sampling sites which are around by other stationary emission sources are found with elevated PCDD/F level.After four year’s operation, the dioxin level of ambient air, vegetation and soil nearby Gangshan and Kanding MSWI still maintain in the same level. By analyses with the t test, there is no significant difference on the dioxin level after four year’s operation.
