(1)因應環保署「特殊性工業區緩衝地帶及空氣品質監測設施設置標準」(以下簡稱「特殊性工業區設置標準」)規定，雲林六輕工業區設有10個測站，其中包括有害空氣污染物監測；本項工作收集民國106年至107年特殊性工業區HAPs物種監測資料並參考美國聯邦環保署環境大氣有害空氣污染物年報之篩選原則，針對34項標的HAPs物種(26項VOCs、7項重金屬及戴奧辛)解析重要HAPs。解析結果顯示，雲林縣特殊性工業區環境大氣苯、乙苯、砷、鎳、鎘及鉛為篩選所得之重要物種。比較重要HAPs物種濃度與國外環境濃度參考值(世界衛生組織、歐盟執委會、澳洲國家環境保護局、日本環境省以及美國德州環境品質委員會(TCEQ))，苯及砷濃度值與國外參考值較為接近，其餘物種濃度皆遠低於國外訂定之環境參考值。 (2)於分析環保署固定污染源有害空氣污染物策略與法規研訂情形之工作，環保署管制策略以技術基準為主、健康風險為輔之管制主軸方向；並因應空氣污染防制法修正發布，已公告「第一批固定污染源有害空氣污染物種類及排放限值」、「固定污染源有害空氣污染物健康風險評估作業方式」、「應設置空氣污染防制專責單位或人員及健康風險評估專責人員之公私場所」，以及修正發布「環境保護專責及技術人員訓練管理辦法」與「空氣污染防制專責單位或人員設置及管理辦法」，亦預告固定污染源有害空氣污染物排放標準(草案)。同時，計畫亦完成環保署排放量申報及許可制度納入有害空氣污染物之做法解析，提供環保局後續研擬因應策略參考。氯乙烯及聚氯乙烯製造業管制及排放標準法規符合度則顯示台灣塑膠工業(股)公司麥寮廠氯乙烯製程(M11)及聚氯乙烯製程(M71及M72)等3製程已完成或執行改善作業。 (3)由分析民國105年至107年之空氣污染防制費有害揮發性有機物排放資料顯示，雲林縣歷年排放量皆以製程排放貢獻最大，佔排放總量比例達85%以上；排放量大之物種包括甲苯、二甲苯、苯、苯乙烯、二氯甲烷等，佔排放量之95%以上。以毒性排放權重評估物種重要性顯示，三氯甲烷、1,2-二氯乙烷、苯、二甲苯、三氯乙烯為較重要物種。以8項重要物種彙整優先納管排放源，含最多重要物種數量之公私場所為台塑石化(股)公司麥寮一廠，有6項於此工廠有排放，其次為台灣化學纖維(股)公司麥寮廠(純對苯二甲酸廠)，排放5項重要物種，為建議可優先調查之排放源。以可得之環保署固定污染源許可資料庫分析可能受有害空氣污染物法規管制影響之產業，篩出32家/61個製程為應設置健康風險評估專責人員之行業別/製程對象，並列出5項訂有管道排放限值之HAPs物種於雲林縣可能之固定污染源，其中戴奧辛約20家、鎘及其化合物為3家、三氯乙烯有10家、氯乙烯1家、鉛及其化合物為74家。 (4)VOCs連續監測工作自完成北方位點(許厝寮漁港直銷中心)與宿舍站(海豐宿舍)架設後進行監測，至12月31日共計完成67站日監測結果，北方位點與宿舍站共計進行2次測站修復性維護，總有效數據筆數達97.5%；移動監測作業於12月21日完成5站次共計10次移動監測。 (5)整體固定站監測結果，漁市站所有測項的平均濃度皆低於1.0 ppb以下。宿舍站所有測項的平均濃度也都在5.1 ppb以下，而乙苯、間與對二甲苯、鄰二甲苯和苯乙烯在12月10日有一筆高值事件，此外丙烯、異戊烷和苯具有較高的背景濃度。 (6)整體移動監測監測結果，蚊港聚落以丙烯和甲苯為主；新興國小於監測期間有一筆高值事件，tVOC達384.0 ppb；豐安國小監測期間高值集中於凌晨，主要物種為丙烯、丙酮、1,2-二氯乙烷和甲苯；崙豐國小除了丙烯、丙酮和甲苯外，其餘測項平均濃度皆低於1.0 ppb；海豐分校除了丙酮和苯，其餘測項平均濃度皆低於0.1 ppb。

(1) The ambient hazardous air pollutant (HAP) monitoring data from Mai-Liao special industrial park were collected, included 26 Volatile organic compounds, 7 heavy metals, and dioxins. Analysis method was followed US EPA’s National Monitoring Programs. The results showed that the benzene, ethylbenzene, arsenic, nickel, cadmium and lead are the important HAP species in ambient air in Yunlin. Comparison of the important HAPs species concentration with reference ambient air concentration were also conducted in this study. The reference concentrations are including the air quality guideline from World Health Organization, the air quality target or limit value from European Commission, the national environment protection measure standard from Australia National Environment Protection Council, and the environmental standard or guideline from Japanese Ministry of the Environment, and the long-term health air monitoring comparison values from Texas Environmental Quality Commission. The ambient concentrations of benzene and arsenic are relatively close to those reference values, and the concentration of other four species is far lower than those reference values. (2) In analyzing the HAPs control strategy and regulations of stationary sources that established by Taiwan Environmental Protection Agency (Taiwan EPA), showed that the strategy is technology-based and supplemented by health-risk based. Five regulations which were related with HAP control have established by Taiwan EPA under the authority of Air Pollutant Control Act, those regulations are “List of hazardous air pollutants and emission limits of the first batch of stationary sources”, “Health risk assessment process of hazardous air pollutants from stationary sources”, “List of public and private places which should be set up for air pollution prevention units or personnel and health risk assessment personnel”, “Environmental protection prevention units or personnel training and management ” , and “ Air pollution prevention unit or personnel management”. A draft emission standards for HAP from stationary sources was also announced. The emission reporting and permit system to incorporate HAPs were also analysis in this project. The compliance of Vinyl chloride and polyvinyl chloride manufacturing control and emission standards shows that the 3 processes, i.e., one vinyl chloride process (M11) and two polyvinyl chloride process (M71 and M72) of the Taiwan Plastics Industry Co., Ltd, have been completed or implemented the improve work. (3) According to the analysis of the data on the emission of 13 VOCs from the air pollution fee from 2016 to 2018, the major source are process emissions which accounting for more than 85% of the total emissions. Toluene, xylene, benzene, styrene, and methylene chloride are the species with large emission, they accounting for more than 95% of emissions. In the view of toxicity-emission weighting, chloroform, 1,2-dichloroethane, benzene, xylene, and trichloro-ethylene are the more important species. Six important HAPs are emitted from Formosa Petrochemical Corporation Mai-Liao No. 1 Plant, followed by Taiwan Chemical Fiber Company Mai-Liao plant emits 5 important species, those two plants are the source of emissions that can be investigated as a priority. Using the available permit database of stationary source to analyze industries that may be affected by the HAP regulations, 32 companies and 61 processes were screened out as the public and private plants which should be set up for air pollution prevention units or personnel and health risk assessment personnel. The public and private plants that may subjected to the regulation of emission limits are also listed, the number of plants are 20 for dioxins, 3 for cadmium and its compounds, 10 for trichloroethylene, 1 for vinyl chloride, and 74 for lead and compounds. (4) The continuous monitoring work of VOCs has been completed since the establishment of the northern site (Xucuoliao Port Direct Sales Center) and the dormitory station (Haifeng Dormitory). The total of 67 station-day monitoring results has been completed as of December 31, and the total of the northern site and the dormitory station Carried out two times of remedial maintenance of the station, the total number of valid data reached 97.5%; The mobile monitoring operation completed a total of 10 mobile monitorings at 5 stations on December 21. (5) As a result of the overall fixed station monitoring results, the average concentration of all items at the fish market station is below 1.0 ppb. The average concentration of all compounds in the dormitory station was also below 5.1 ppb, while Ethylbenzene, m, p-Xylene, o-Xylene and Styrene had a high-value event on December 10, in addition Propene, Isopentane and Benzene had higher background concentration. (6) According to the overall mobile monitoring results, the Wengang settlements are dominated by Propene and Toluene; Xinxing Elementary School had a high-value event during the monitoring period, tVOC reached 384.0 ppb; During the monitoring period of Fengan Elementary School, the high values were concentrated in the early morning hours. The main species were Propene, Acetone, 1,2-Dichloroethane and Toluene; Except for Propene, Acetone, and Toluene, the average concentration of all other test items in Lunfeng Elementary School is less than 1.0 ppb; In addition to Acetone and Benzene, the average concentration of other test items at Haifeng Branch is less than 0.1 ppb.
