屏東縣固定污染源排放戴奧辛與重金屬檢測與環境介質調查計畫

中文摘要 本計畫調查一座大型焚化爐(A)、一座中小型焚化爐(B)與一座預熱爐(C)，以了解其戴奧辛與重金屬的排放情形。研究發現此三污染源之戴奧辛的排放濃度分別為0.0950、0.121與 0.0125 ng I-TEQ/Nm3，均符合法規。其戴奧辛年排放量依序分別為排放量分別為0.788、4.14與0.121 μg I-TEQ /Y。另外大型垃圾焚化爐煙道廢氣中鉛總濃度平均為0.0448 mg/Nm3，鎘總濃度平均為0.00554 mg/Nm3，汞總濃度平均為0.00640 mg/Nm3；年排放量分別為88.5、12.6與10.9 kg /Y。中小型廢棄物焚化爐煙道廢氣中重金屬之鉛總濃度平均為1.27 mg/Nm3，鎘總濃度平均為0.0178 mg/Nm3，汞總濃度均為ND；年排放量分別為109、1.53與NA kg /Y。預熱爐煙道廢氣中重金屬鉛總濃度平均為0.464 mg/Nm3，鎘總濃度平均為0.0603 mg/Nm3，汞總濃度平均為0.0024 mg/Nm3；年排放量分別為24.8、3.22與0.192 kg /Y。此外,大型垃圾焚化爐周界大氣、土壤與植物採樣點總I-TEQ平均濃度分別為0.0427 pg I-TEQ/Nm3、8.48與1.31 ng I-TEQ/kg，而其周界大氣、土壤與植物上下風處採樣點之特徵剖面皆相似，分別以OCDD所占比例最高。

Investigation on dioxin and heavy metal emissions from stationary sources and in the environmental media in Pingtung County

英文摘要 One large scale municipal solid waste incinerator (A), one middle/small incinerators (B) and one smelting plant (C) were investigated in this study. Experimental results showed that PCDD/F concentrations of A, B, and C were 0.0950, 0.121, and 0.0125ng I-TEQ/Nm3, and their annual PCDD/F emissions were 0.788, 4.14, and 0.121 μg I-TEQ, respectively. All of them are lower than the regulation limit of Taiwan EPA. The metal levels were also observed in this study. The mean contents of Pb, Cd, and Hg of A were 0.0448, 0.00554, and 0.00640 mg/Nm3, respectively, and their annual emissions were 88.5, 12.6, and 10.9 kg/Y, respectively. The mean metal content and the annual emission of Pb, Cd, and Hg of B were 1.27, 0.0178, and ND mg/Nm3, and 109, 1.53, and NA kg/Y, respectively. The mean metal content and the annual emission of Pb, Cd, and Hg of C were 0.464, 0.0603, and 0.00240 mg/Nm3, and 24.8, 3.22, and 0.192 kg/Y, respectively. Moreover, the mean PCDD/Fs level in ambient air, soil, and vegetation nearby the large scale municipal solid waste incinerator were 0.0427 pg I-TEQ/Nm3, 8.48, and 1.31 ng I-TEQ/kg, respectively.
