1. Inspection of dioxin and metal air pollutant from stationary pollution sources and examination of documentation
（1）We have completed the compliance inspection of 68 companies/85 stacks. Among these companies, 57/75 are in operations; 4/4 （Ener-Com Technology Co., Ltd. Datong plant, Taoyuan refinery of China Petroleum Corporation-M33, Environmental Analysis Laboratory EPA, Executive Yuan, R.O.C, and Great Bell Printing & Dyeing Co., Ltd.）have applied temporarily shut down; 3/3 （Dingsin Co., Ltd., Boyu plasma Co., Ltd., and Sun-ho fiber Co., Ltd.）shut down without advanced permit application; 4/4 （Alpha Beta Enterprise Co., Ltd., Chang-Hua fiber Co., Ltd., Chun Hsin Chi Co., Ltd., and Huang textile Co., Ltd.）are removed from control list. The companies in operation include 14 incinerators/19 stacks, 3 electric arc furnaces/3 stacks, 21 auxiliary fuel/26 stacks, 22 stationary pollution source /30 stacks listed in the 8th announcement.
（2）We have completed documentation examinations of 134 cases, including dioxin testing reports and dioxin testing plans. 53 of them were keyed into the stationary pollution source information management system and Taiwan toxic substance pollutant information management system. We have carried out 26 on-site inspections of dioxin sampling at controlled dioxin source. All accorded to regulation.
（3）We have completed the inspection and testing of stack dioxin from 12 companies, a total of 38 dioxin samplings and analyses were carried out. Three companies（Nan-Yang Dyeing & Finish Co., Ltd., Minchali Metal Industry Co., Ltd. and Ener-ComTechnology Co., Ltd.） violated the dioxin emission standard and was fined NT$ 450,000, NT$ 150,000, NT$ 450,000,and they all have completed improvements on due time; We also have completed the inspection and testing of stack metal from 3 companies, the metal conformed to dioxin emission standard.
（4）Dioxin testing data from 68 dioxin air pollutant from stationary pollution sources （219 cases） were collected. The estimated annual dioxin emission was 0.860 g-TEQ/year from incinerators, 0.285 g-TEQ/year from plants using auxiliary-fuel, 3.609 g-TEQ/year from electric arc furnaces, and 1.804 g-TEQ/year from stationary polluting sources. The Taoyuan County annual dioxin emission is 6.558 g-TEQ/year
（5）Control and reduction of dioxin emission source
We have carried out on-site consultation at AMIA Co., Ltd. on 12/28/2009, respectively. A report of recommending improvements based on the problems and deficiencies found on-site was provided to AMIA Co., Ltd., for reference. AMIA Co., Ltd. invited to air pollution control equipment manufacturers for equipment description, and will plan to addition of activated carbon injection systems and dust collection device before the original scrubber to help to reduce dioxin emissions.
（6） We use RFID on activated carbon management system and test the management system in HongCheng Technology Co., Ltd.. We also hold "RFID technology demonstration cum stationary pollution sources dioxin online reporting system Workshop" in the Taoyuan County Government on 12/10/2009.
2. Investigation of ambient air dioxin / PCBs
We have sampled 28 ambient air samples for dioxin testing. The dioxin toxic equivalency (TEQ) range in ambient air was 0.024 ~ 0.536 pg-TEQ/Nm3 in GuanYin industrial park, DaYuan industrial park and Gueishan industrial park. The average concentration of ambient air dioxin is 0.152 pg-TEQ/Nm3 in GuanYin industrial park; 0.225 pg-TEQ/Nm3 in DaYuan industrial park; 0.053 pg-TEQ/Nm3 in Gueishan industrial park. The concentration of ambient air dioxin in Gueishan industrial park is lower than what in GuanYin industrial park and DaYuan industrial park, the reason for only three dioxin emission sources in Gueishan industrial park.
In addition to ambient air dioxin , we also investigated ambient air PCBs. The PCBs toxic equivalency (TEQ) range in ambient air was 0.002 ~ 0.028 pg WHO TEQ/Nm3 in GuanYin industrial park, DaYuan industrial park and Gueishan industrial park. The average concentration of ambient air dioxin is 0.009 pg WHO TEQ/Nm3 in GuanYin industrial park; 0.012 pg WHO TEQ/Nm3 in DaYuan industrial park; 0.004 pg WHO TEQ/Nm3 in Gueishan industrial park. We can find that PCBs / dioxin toxicity equivalent to 5 ~ 20% in past studies, PCBs / dioxin in this plan was between 6 to 8%.
Multivariate statistical analysis reveals that the values in GuanYin industrial park might be related to waste burning and wood boiler; in DaYuan industrial park might be related to wood boiler, the dispersion of pollutants from MSWI electrostatic dust collector and waste burning; in Gueishan industrial park might be related to wood boiler
3. Investigation of ambient air heavy metals
We use PCA to analysis the concentration of ambient air heavy metals and the inspection and testing of stack metals in GuanYin industrial park and DaYuan industrial park, and the result reveals that the ambient air heavy metals of Guan-Yin elementary school in winter be related to Super Max Engineering Enterprise Co., Ltd.,; the ambient air PM10 heavy metals of Chao-Yin elementary school be related to Yung-Yuan Chemical Industry Co., Ltd..
4. Control and Investigation of industrial park and high pollution potential areas
We have investigatd 6 elementary school in GuanYin industrial park, DaYuan industrial park and Gueishan industrial park for VOCs, and found that Shu-Lin elementary school, Jian-Guo elementary school and Chao-Yin elementary school were effected by the pollutions from industrial park. We are sure that the pollutions are foul, and some of them are SF6, Freon 12 and Freon 22 etc.
