The annual emissions and emission factors of stationary sources were used to update and establish the emission inventory of dioxin and heavy metals. The achievements of this project are described as below: 1.The mean total PCDD/Fs concentrations of stationary sources A, B, C, D, and E were 0.085, 0.018, 0.158, 0.071 and 0.025 ng I-TEQ/Nm3, respectively. All of them are lower than the regulation limit of Taiwan EPA and previous emission levels of factory. 2.The concentrations of Pb, Cd and Hg of secondary aluminum smelter B were all below the detection limit. The mean Pb concentrations of large scale MSWI E were 0.0728 mg/Nm3; those of Cd and Hg were below the detection limit. 3.For waste-liquid incinerator A, the most abundant congeners were OCDD and 1,2,3,4,6,7,8-HpCDD.

All of them are lower than the regulation limit of Taiwan EPA (1000 ng I-TEQ/kg). 6.The annual PCDD/Fs emissions in Pingtung County were obtained as 0.164 g I-TEQ/yr. The major PCDD/Fs emission sources were incinerator (36.8%), secondary aluminum smelter (61.8%), and crematorium (1.4%). 7.The PCDD/Fs emission of waste-liquid incinerator A, secondary aluminum smelter C, and large scale MSWI E were estimated in this project. Waste-liquid incinerator A needs to analyze chlorine composition of feedstock, and to control a stable operating condition. Secondary aluminum smelter C needs to estimate and adjust the equipment for reducing the PCDD/Fs production. Large scale MSWI E needs to make efforts in the management of bottom ashes and the treatment of soil. 8.This project reviewed current controlling policies and reducing targets for PCDD/Fs and heavy metals by Taiwan EPA. According to the controlling policies of EPA, this project further reported a managed method of PCDD/Fs and heavy metals for Pingtung County. According to previous results of the PCDD/Fs emissions in Pingtung County, the PCDD/Fs emissions in 2002, 2007, and 2010 were 2.2, 0.6, 0.164 g I-TEQ/yr, respectively. The results indicated that Pingtung County has a significant achievement for reducing PCDD/Fs emission. However, there are need to give an education and management strategy for open burning.
