Production of antioxidants was investigated in needles of fir (Abies alba Mill.) and spruce (Picea abies (L.) Karst) after exposure to low concentrations of SO(2), O(3), and a combination of both pollutants. Glutathione reacted most sensitively to pollutants followed by vitamin E and vitamin C. In spruce needles, the overall increase of antioxidants after exposure to air pollutants was lower than in needles of fir. SO(2) was more potent than O(3). Maximum increase of antioxidants was found in needles after exposure of trees to SO(2) + O(3).
研究了低浓度 SO2、O3 及其混合污染物暴露后，冷杉（Abies alba Mill.）和云杉（Picea abies（L.）Karst）针叶中的抗氧化剂的产生情况。谷胱甘肽对污染物的反应最敏感，其次是维生素 E 和维生素 C。在云杉针叶中，暴露于空气污染物后抗氧化剂的总体增加量低于冷杉针叶。SO2 的作用强于 O3。在树木暴露于 SO2+O3 后，针叶中的抗氧化剂增加最多。
