中文摘要 | 為瞭解台灣西北部沿海地區農業環境的空氣污染情形,於1991-1993年在林口電廠、觀音工業區及東華合成纖維廠附近農田,分別設立監測點,利用盆栽方式栽植敏感的指標植物如唐菖蒲、番石榴,進行空氣污染監測。監測結果,林口電廠西南南方唐菖蒲葉片焦桔長度與葉片中含硫量有明顯的相關性存在,唯西南西方則無相關性存在,顯示此處空氣污染對唐菖蒲的危害除硫外,尚受東北季風吹襲的影響;觀音工業區西南方唐菖蒲受害葉枯長度,與工業區距離呈反比,與空氣中硫含量無關,可能係受東北風挾帶工業區排放之其他污染物影響所致;東華合成纖維廠西南方唐菖蒲受害分佈成帶狀,可能與工廠排放廢氣有關,唯葉片中含硫量並未隨葉枯程度增加。 |
英文摘要 | During the period of 1991-1993, five monitoring points were set up in the fields near Linkow Power Plant, Kwang- Yin Industrial Park and Tung- Hua Textile Plant separately to assess the air pollution in agricultural areas of North-western Taiwan. Potted gladiolus and guava plants were used as indicator plants Subjected to open air pollution. The injury degree of plants wene deter-mined by measuring the leaf length of damaged portion. The degree of injury was related to the sulphur contents of leaves, at the monitoring point in south-southwest of Linkow Power Plant, but not west-south west. The results showed that the leaf injury of gladiolus plant was not only caused by air pollution of sulphur dioxide polluted air, but also affected by northeast monsoon. At the monitoring point in the southwest of Kwangyin Industrial Park, the leaf injury of gladiolus was related inversely to the distance from the industrial park, but not related to the sulphur contents of air 'The injury might be caused by some other pollutants from the industrial park carried by northeast monsoon. At the monitoring point in the southwest of Tung- Hwa Textial Plant, the long bleached lesion was observed on plants, probably due to the waste gases emitted from the plant, however, no relationship between the leaf injury and sulphur contents of leaves was recognized. |
