Lipid peroxidation: A phytotoxic consequence of air pollutants

Abstract

Spruce and fir, both 10 years of age, were exposed to purified air, ozone (0.14 mg/m/sup 3/ air), SO/sub 2/ (0.03 mg/m/sup 3/ air), or a combination of both gases in open top chambers. With age, a combination of both gases significantly increased the content of the antioxidants vitamin E and C and glutathione in needles of fir and spruce when compared to the control treated with purified air. The increase was stronger in needles of fir than in needles of spruce. Further, the increase was already found in the youngest needles of fir. Compared to the control, no significant higher amount of antioxidants was observed when trees were exposed to ozone alone. Moreover, ozone exposure was less effective than SO/sub 2/ exposure. Combination of both air pollutants induced synergistic effects. In field studies (location: Schwarzwald, Kaelbelescheuer/Haldenhof), needles of spruce also showed an increase in the vitamin E content dependent on the extent of damage. This increase was partly accompanied by a higher amount of vitamin C and an increased degree of lipid peroxidation, measured as ethane production. Our results from open top experiments are consistent with our previous data investigating natural aging in higher plants. Therefore we suggest that  More>>

Our results from open top experiments are consistent with our previous data investigating natural aging in higher plants. Therefore we suggest that by the phytotoxic action of air pollutants, such as SO/sub 2/ and SO/sub 2/ + ozone, age-related peroxidative processes are accelerated. Further, both vitamin E and glutathione are specific indicators of these processes. By now, no direct and significant correlation between field studies and studies with open tops has been found.}
