台東廠大氣、植物及土壤PCDD/Fs總I-TEQ平均濃度分別為0.0233 pg I-TEQ/Nm3、1.37與0.892 ng I-TEQ/kg。藉由濃度之等位軌跡圖發現大氣總PCDD/Fs濃度變化與台東廠並無明顯關係，另從PCDD/Fs特徵剖面進行階層集群分析，推測台東廠周界大氣應是受到蒸氣鍋爐程序及移動性污染的影響。由上可知台東廠試運轉階段所排放之PCDD/Fs對周界環境之影響並不顯著。林內廠大氣、植物及土壤PCDD/Fs總I-TEQ濃度平均濃度分別為0.0879 pg I-TEQ/Nm3、1.79 與2.50 ng I-TEQ/kg。從PCDD/Fs特徵剖面進行主要成分分析結果顯示整個林內廠周界大氣的特徵剖面較靠近露天農廢燃燒。樹林廠大氣、植物及土壤PCDD/Fs總I-TEQ平均濃度分別為0.120 pg I-TEQ/Nm3、4.61 與4.00 ng I-TEQ/kg。從PCDD/Fs特徵剖面進行主要成分分析之結果，推測三多國小、柑園國小及鶯歌國中受到其他固定污染源之影響，由上可知樹林廠對於周界大氣PCDD/Fs影響輕微。

The mean PCDD/F concentrations in ambient air nearby Shulin, Linnei and Taidong municipal solid waste incinerators (MSWIs) are 0.120, 0.0879 and 0.0233 pg I-TEQ/Nm3, respectively. The mean PCDD/F contents in Ficus leaves nearby these three MSWIs are 4.61、1.79 and 1.37 pg I-TEQ/g, respectively. The mean PCDD/F contents in soil nearby these three MSWIs are 4.00, 2.50 and 0.892 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 Shulin 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.
