Roadside trees that have been chronically influenced by air pollutants need to build up their resistance and develop a tolerance. Antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. For comparative studies, plant samples of spindle tree, Euonymus japonica, were collected from a clean control area (Kijang) and an industrial area (Onsan) which is one of the heavily polluted areas in Korea. The leaves were irradiated with 0, 50 and 100 Gy of gamma rays from a 60Co isotopic source, and evaluated for the level of superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), and lipid peroxidation (LPO). In this study, air pollution-stressed plants showed better adaptation to ionizing radiation (IR) stress. The plant from Onsan exposed to 50 and 100 Gy of IR didn't show any changes of antioxidant enzymes (SOD, CAT and GR) and the LPO due to their enhanced antioxidant capacity than those grown in Kijang. Until 6 hours after irradiation, the samples from Kijang showed apparent increase in the enzymes activities and the level of LPO. These biochemical differences after irradiation between plants which were adapted to their own air environment can be applied to the plant bioassay as an environmental monitoring technique.
