台化停工後,彰化的天空真的不一樣了。
環保團體-台灣健康空氣行動聯盟今(14)日公布環保署空氣品質監測站所測得的資料
,發現台化停工前後,彰化及南台中空氣品質出現顯著改善,以距離台化3 公里的
彰化空品站,SO2和PM2.5濃度降低最明顯,其中SO2降低38%,PM2.5減少47%。
SO2降低38%,PM2.5減少47%
台灣健康空氣行動聯盟執行長楊澤民博士表示,台化停工後,彰化空氣品質出現改善
,這與台化停止燃煤發電,大量減少硫氧化物和粒狀物一定有關,但有多少影響尚待
進一步觀察研究。

台化燃煤發電停止,工廠也跟著停工,在台化停工後,過去日夜然燒的三支煙囪不再
日夜冒煙,這對於彰化人來說是半個世紀以來難得的景象,因為過去只要一入秋,彰
化的天空就灰灰暗暗,陽光不容易露臉,但是這幾天許多住在彰化的民眾都明顯的感
受到彰化的空氣變好,天空跟過去不一樣,彰化八卦山的天空變藍了。
其實民眾的感受最真實,因為根據環保署公佈的數據,確實也顯示出彰化的空氣品質
改善了。
台灣健康空氣行動聯盟執行長楊澤民博士表示,有夥伴根據環保署的監測資料,比較
台化停工前後,距離台化3 公里的彰化空品測站空氣污染物濃度的變化,由於台化燃
煤鍋爐在10/7上午全數停機,因此以10/8-10/12這五天的平均值跟9月工作日的平均
值比較,發現SO2和PM2.5濃度有明顯降低。
根據彰化空品測站所監測到數據,10/8-10/12這五天的平均值跟9月工作日的平均值
比較發現到SO2降低38%,PM2.5減少47%。

一河之隔的台中西屯空氣也變好
由於近日中部地區空品都還不錯,為釐清是否為大氣環境的影響,環保團體也統計選
取中部幾個測站來做比較,發現苗栗、豐原、西屯、二林、新港的SO2和PM2.5也有下
降,但以西屯站和彰化站的降幅最大,SO2降幅高於其他測站三成以上,PM2.5的降幅
則略多一成。
楊澤民認為,這極有可能是因為少了台化這個固定污染源所致,但目前尚無法如此定
論,需要更長時間的觀察,以及更多監測數據佐證。
主婦聯盟台中分會會長張明純表示,彰化市跟台中僅一河之隔,夏天吹南風時,台化
的污染就會飄到台中,甚至烏日、大肚還能聞到台化的臭味,現在台化終於停工,彰
化市區少了大污染源,沒想到不只彰化測站的空品變好,居然連距離台化11公里的西
屯站也變好了,這正說明了中彰真是脣齒相依,中部空品區是互相影響。
