The effects of sulfur dioxide, cadmium and copper on some antioxidative enzymes were studied in Lemna. Superoxide dismutase activity was enhanced after treatment with each of these pollutants. The maximum increase in superoxide dismutase activity was observed after 24 hours of sulfur dioxide fumigation. Lemna exhibited a rapid response to environmental pollutants. In untreated Lemna, catalase was found to be the dominant antiperoxidative enzyme. Sulfur dioxide inhibited catalase activity, but enhanced the guaiacol peroxidase and ascorbate peroxidase activities. After the cadmium and copper treatments, activities of all three of these antiperoxidative enzymes were enhanced. |
