摘要

為瞭解桃園沿海農業區受空氣中氟化物污染情形，於1994～1996年在林口發電廠、觀音工業區及觀音鄉廣興工廠鄰近地區，分別設立監測站，利用盆栽種植指標植物唐菖蒲，並放置HP-19型氟化物偵測儀，進行氟化物氣體污染監測，結果在林口發電廠西南方，唐菖蒲葉尖呈棕褐色枯乾，其葉枯長度較對照區長，葉片氟含量亦較高。其中1996年葉尖枯乾長度與葉片氟、鈉含量皆呈明顯正相關，顯示此地區唐菖蒲的受害，除硫之外，可能與空氣中含氟化物、鹽沫等隨東北季風長期吹襲有關。觀音工業區西南方鄰近空氣，約10%之時間 測得含氟量達0.1～0.5ppb，而唐菖蒲葉尖呈褐色枯乾，受害葉枯長度與葉片中氟含量成正比，且與工業區之距離呈負相關，顯示此處唐菖蒲葉尖受害，係受工業區排放含氟化物及其他氣體污染所致。廣興工廠鄰近唐菖蒲葉脈間呈白色塊斑枯乾，與氟化物為害徵狀相同，氟含量最高達55ppm以上，顯示此處唐菖蒲葉片受害與工廠排放含氟廢氣污染有關。

In order to understand the air pollution of fluoride in agricultural area along the Taoyuan west coasts, several monitor stations were set up near by Linkow power plant, Kwang-yin and Goang-shing industrial parks, Potted gladiolus and HP-19 model fluoride detector were equiped for monitoring the air pollution of fluoride during 1994-1996. At the southwestern of Linkow power plant, the tip leaves of gladiolus were scorched with brown color. Higher fluoride content and longer scorched leaves of gladiolus were found at monitor station than at the control station. The length of scorched leaves of gladiolus was positively correlated with the contents fluoride and sodium in 1996. These showed that the damage of leaves might caused by the fluoride and salt mist carried by northeastern monsoon and was not simply due to sulfur only. Near by southwestern region of Kwang-yin industrial parks, the fluoride contents in the air were measured about 0.1 to 0.5 ppb around 10% of test duration, thus tip leaves of gladiolus were resulted in scorched with brown color. The leaves of tip leaves scorch was positively correlated with the fluoride contents and negatively correlated with the distance from the industrial park. The damage of leaves of gladiolus in Goang-shing industrial park was similar to that of Kwang-yin industrial park, and its maximum fluoride content was over 55 ppm. These showed that the scorched leaves of gladiolus in both industrial parks were correlated with the fluoride waste air emitted from factories in the industrial park.
