Abstract
Production of antioxidants was investigated in needles of fir (Abies alba Mill.) and spruce (Picea abies (L.) Karst) after exposure to low concentrations of SO2, O3, 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. SO2 was more potent than O3. Maximum increase of antioxidants was found in needles after exposure of trees to SO2 + O3.This publication has 11 references indexed in Scilit:
