Abstract One hundred and twenty female mice fed diets containing various levels of vitamin E were continuously exposed to 0.5 ppM, 1.0 ppM nitrogen dioxide (NO2), and filtered air for 17 months. Blood, lung, and liver tissues were assayed for glutathione peroxidase (GSH-peroxidase) activity. Exposure to 0.5 ppM NO2 did not affect blood and lung GSH-peroxidase activity; 1.0 ppM NO2 exposure however, caused suppression of the enzyme. A combination of vitamin E deficiency and 1.0 ppM NO2 exposure resulted in the lowest GSH-peroxidase activities in the blood and lung. High levels of vitamin E in the diet resulted in elevated GSH-peroxidase in the blood and lung. Liver GSH-peroxidase activity was unaffected by either dietary vitamin E or NO2 exposure.
