#境外與中鋼
每次中國塵霾會吹入台灣時,環保署常會開記者會提醒民眾防範。以今年境外影響較大之
2017/12/05來看,的確環保署之預報相當準確,也值得嘉許。
但我事後之分析,以汚染最嚴重之高屏地區,如小港站。在境外影響最嚴重之12/05而言
,影響雖達16 ug/m3,佔比也不到三成,為28%,略高於中鋼対小港之影響。但這星期之
其他六天,中鋼対小港之影響皆遠大於境外的影響。而其他幾天高雄之汚染也相當嚴重,
每天PM2.5皆超過空氣品質標準35 ug/m3,而中鋼之影響平均達11 ug/m3,而同期境外之
影響平均為7 ug/m3。
環保署真的不用常開記者會強調境外之影響。反而應好好強調境內之影響及改善之道。以
12/05而言,我的分析対PM2.5之汚染佔比,工廠佔比最高達56%,交通含船舶16%,溢散源
為10%,而境外為28%。
工廠中全台前二十大以外之中小工廠影響佔14ug/m3,佔25%。這些中小工廠多燃燒重油,
成本已高過使用天然氣作燃料,應該優先來改進。
而前二十工廠在12/05対PM2.5之影響佔比達31%。而這前二十大工廠,多是國營事業如中
鋼、台電、中油及中龍。及民間的台塑集團及水泥業者。國營事業真的要深自檢討,是否
有任何改進之空間。而民間之部分可能只有靠大幅調高空汚費約100倍,才能產生經濟誘
因,促其改善。
交通汚染源之部分的確主要是老舊柴油車及船舶汚染,老舊柴油車部分,也從增加汽油每
公升之空汚費0.2元,柴油0.4元之空汚費來補助加速淘汰。船舶汚染主要就看我們是否能
仿效歐洲要求船舶必需改用天然氣為燃料,才允許進港。
溢散源部份看到環保局貼出幾乎每日都在加強掃洗街,相信已控制到非常好的狀況了。
我一直相信,讓高屏可以常見初冬藍是可能的,但除了高雄要努力外,上風處台灣西部所
有縣市都要努力,才有可能。方案也都清楚,只要如上面建議,3年內一定可以讓高屏民
眾常見初冬藍。
