This project is management and assistance of dioxin emission and supported the investigation of environmental pollution cases in 2008.

英文摘要 Project Execution Organization: National Tsing Hua University Principal Investigator: Yong-Chien Ling Project Period: 2008-5-6 ~ 2009-5-5 Project Funding: NT$ 10,200,000 1. Control of dioxin air pollutant from stationary pollution sources Inspection and testing: We have completed the inspection and testing of stack dioxin from 12 companies, including YuHong Technology Co., HongCheng Technology Co., (twice), Ener-Com Technology Co., YuenFoongYu Paper Mfg. Co.,Ltd. TaoYuan Mill, Super Mas Engineering Enterprise Co., Ltd., King Shine Co., Ltd,Funeral Affairs Administration of Jungli City Taoyuan County, Sino-Prosperity Iron &Steel Co., Ltd., Yung-Yuan Steel Co., Ltd., Guo-Cheng Industrial Co., Ltd. TaoYuan 1st Mill, Hsin-Yung Enterprise Co., Ltd. A total of 38 dioxin samplings and analyses were carried out. Three companies (YuHong Technology Co., HongCheng Technology Co., and Ener-ComTechnology Co.) violated the dioxin emission standard and was fined NT$ 900,000, NT$ 300,000, NT$ 300,000, respectively. They all have completed improvements on due time. The dioxin measured after improvements conformed to dioxin emission standard. Inspection of compliance: We have completed the compliance inspection of 75 companies/96 stacks (113 cases). Among these companies, 56/72 are in operations;3/3 (Chiuan-Fu Printing & Dyeing Co., Ltd., GODA Technology Co., Ltd,Guo-Cheng Industrial Co., Ltd. TaoYuan 1st Mill) are at testing stage; 3/3 (Shang-Ho Fiber Co., Ltd., Alpha Beta Enterprise Co., Ltd., Ting-Sin Tech. Industrial Co., Ltd.)shut down without advanced permit application; 2/2 (Environmental Analysis Laboratory of Taiwan’s EPA, Ho-Chiun Fiber Co., Ltd.) have applied temporarily shut down; 14/16 are removed from control list. The companies in operation include 18 incinerators/23 stacks, 3 electric arc furnaces/3 stacks, 22 auxiliary fuel/26 stacks, 20 stationary pollution source /26 stacks listed in the 8th announcement. The sampling platform at 2 companies (Far Eastern Textile Ltd. Kuanyin Textile Plant, Sunflower Co., Ltd. firstly regulated in year 2008) did not conform to regulation. Most of the non-conformed cases are non-conformed sampling platform (13 cases) followed by exceeding the periodic sampling and testing date (5 cases).Examination of documentation: We have completed documentation examinations of 173 cases, including dioxin testing reports and dioxin testing plans. 61 of them were keyed into the stationary pollution source information management system and Taiwan toxic substance pollutant information management system. We have carried out 37 on-site inspections of dioxin sampling at controlled dioxin source. All accorded to regulation.The estimation of annual dioxin emission: Dioxin testing data from 18 incinerators, 12 copper secondary smelting, 2 aluminum secondary smelting, 2 other metal secondary smelting, 3 iron smelting electric arc furnace, 4 steam-electricity co-generation electricity power plant using coal-fired boiler, and 22 plants with industrial waste as auxiliary fuel were collected. The estimated annual dioxin emission was 0.059 g-TEQ/year from large-sized incinerators, 0.090 g-TEQ/year from medium-sized incinerator, 0.391 g-TEQ/year from small-sized incinerator, 0.271 g-TEQ/year from plants using auxiliary-fuel, 5.538 g-TEQ/year from electric arc furnaces, and 2.121 g-TEQ/year from stationary polluting sources. The Taoyuan County annual dioxin emission is 8.47 g-TEQ/year 2. Control and reduction of dioxin emission source We have carried out on-site consultation at Yi-Tzeng Co., Ltd and TungHo Steel Enterprise Co., Ltd on 10/20/2008, 2/26/2009, and 3/7/2009, respectively. A report of recommending improvements based on the problems and deficiencies found on-site was provided to r Yi-Tzeng Co., Ltd and TungHo Steel Enterprise Co., Ltd.respectively, for reference. 3. Investigation of ambient air dioxin We have sampled 24 ambient air samples for dioxin testing. The average dioxin toxic equivalency (TEQ) in ambient air was 0.220, 0.070, 0.200, and 0.231pg-TEQ/Nm3 in DaYuan industrial park; 0.068, 0.472, 0.172, and 0.069 pg-TEQ/Nm3 in GuanYin industrial park; 0.032 and 0.104 pg-TEQ/Nm3 in dense inhabitant area;0.013 and 0.067 pg-TEQ/Nm3 in intersection area between Taipei County and Taiyuan County; 0.011 and 0.023 pg-TEQ/Nm3 in rural area. The 2nd seasonal measured value at GuanYin elementary school is higher than the Japan standard (0.6 pg-TEQ/Nm3) of ambient air dioxin. Multivariate statistical analysis reveals that the abnormal values might be related to waste burning.The dioxin exposure dosage from ambient air for adult residents living in DaYuan and GuanYin township is between 0.011~0.286 pg-TEQ/kg b.w./day; whereas those living in dense inhabitant area is between 0.007~0.057 pg-TEQ/kg b.w./day. These values are lower than the calculated tolerable dioxin intake value (0.2 pg-TEQ/kg b.w./day) and lie in the acceptable range. 4. Investigation of ambient air heavy metals We have sampled 24, 12, and 12 ambient air TSP, PM10 and PM2.5 samples, respectively, for heavy metals testing. The average heavy metals concentration in ambient air TSP, PM10 and PM2.5 was 0.370g/Nm3, 0.0066 g/Nm3, and 0.0051g/Nm3 respectively in GuanYin township; 0.320g/Nm3, 0.0037 g/Nm3, and0.0035g/Nm3 respectively in DaYuan township; 0.261g/Nm3, 0.0017 g/Nm3PM10, and 0.0012g/Nm3 in dense inhabitant area; 0.192g/Nm3 (TSP) in intersection area between Taipei County and Taoyuan County; 0.188 g/Nm3, 0.0024g/Nm3, and 0.0014g/Nm3 in rural area. These values are lower than control and recommended values. The order of concentration in TSP, PM10 and PM2.5 from high to low is ChaoInn elementary school, ShuLin elementary school, Taoyuan elementary school, and YiSheng elementary school.The highest Cr6+ concentration was found in DongSing junior high school locating at dense inhabitant area. Lowest Cr6+ concentration was found in YiSheng elementary school locating at rural area. 5. Investigation of indoor air quality(IAQ) We have completed the investigation of IAQ in 12 sites/23 samplings and the testing of non-ionized radiation in 12 sites/19 samplings. All measured values do not exceed the Taiwan EPA’s environmental recommended value (6.25 T) and WHO’s standard for nearing electric capable facility (20 T). The frequency of non-conformed IAQ items from high to low is ozone, bacteria, and carbon dioxide.Three sites (Min-Sheng Healthcare/Ching-Kuo campus, Metro Walk shopping center, and Taoyuan international airport) were designated as demonstrating sites for IAQ improvement. The testing results after the completion of improvement works indicated that each site showed significant improvement. Ozone remained the only non-conformed item. 6. Investigation for supporting environmental protection cases We have completed the sampling and testing of volatile hazardous organic compounds in 22 sites. An investigation to identify unknown volatile organic compounds (VOCs) in the administrative department of Taoyuan County Government was carried out on 06/27/2008. An investigation to identify VOCs in ambient air of CPC Co., Refining Business Div., was carried out on 4/11/2008. An investigation to identify VOCs in traffic arteries of Taoyuan County was carried out on 01/05/2009.An investigation to identify VOCs in the stack and plant of Regiant Industrial Co.,Ltd., Shu-Lin elementary school, and surrounding ambient air was carried out on 3/10/2009. An investigation to identify VOCs in the neighboring area of DaYuan industrial park and GuanYin industrial park was carried out on 3/10/2009. In addition,we have completed the emergency sampling and testing of various pollutants in 14 sites. 7. Achievements announcement We have organized the Taoyuan County IAQ Achievements Conference. The project achievements, entitled “Investigation and improvement of current indoor air quality at different kinds of place”, “A study of emission factor from stationary pollution sources”, and “The detection and distribution of ambient air heavy metals in TSP, PM10 and PM2.5 “were presented at 2009 Environmental Analytical Chemistry Conference. It was also presented, entitled “The distribution and source investigation of PBDEs in indoor environment”, at the Fifth Environmental Hormones and Persistent Organic Pollutants Conference and was awarded the best research paper.
