Title: Air pollution effects on food quality. 2nd annual progress report

Abstract

Progress is reported in studies to determine the effect of acute, toxic exposures of ozone to alfalfa, potato, and soybean plants. The objective has been to correlate the foliar response with alterations in quality of the edible portion of the plant viz. the leaf, tuber and seed of alfalfa, potato and soybean, respectively. In 1977 we (1) modified our fumigation facilities, (2) developed protocol for studies with alfalfa and potato, and (3) conducted studies on flavonoid status of alfalfa and a series of parameters of potato tubers. In 1978 we (1) conducted more indepth studies with alfalfa, (2) repeated the potato study, (3) began to develop protocol for measuring additional parameters of alfalfa and potato quality, and (4) developed protocol for cultivating and exposing soybean plants.

  • Preliminary results are reported from a study on the impact of acute foliar exposure to ozone on alfalfa foliage and potato tubers. Alfalfa plants exposed when seven weeks old to 0.20, 0.30, or 0.35 ppM ozone for two to three hours showed no detectable effects from the lowest concentration and slight to severe necrosis of the foliage at the larger concentrations. Potato tuber of two varieties showed only very slight effects on number of tubers produced per plant, total solids as determined by dry weight, and total glycoalkaloids following exposure of plants to 0.20 ppM ozone for 3 hr everymore » second week for up to 110 to 130 days.« less
  • This project studied the potential of ozone (O/sub 3/) or nitrogen dioxide (NO/sub 2/) to alter the quality of potato and alfalfa. Three studies are summarized.
  • The impact of ozone on the qualitative characteristics of potatoes, alfalfa and soybeans is discussed. The impact on yield, total solids, sugar status and tuber glycoalkaloid (TGA) content was measured. The effects of ozone on the leaves were also noted. Field trials were conducted as well as laboratory experiments. (DC)
  • Research in the development of a computer model to simulate and predict SO/sub 2/ injury to vegetation is reported. Laboratory experiments were devoted to studies on the effects of environmental variables on plant response to SO/sub 2/. A model structure was developed and will be implemented as laboratory data are analyzed. Preliminary results of experiments on the effects of light intensity, temperature, and SO/sub 2/ damage to river birch seedlings are reported. Data are presented on the effects of soil moisture stress on pinto bean plant response to SO/sub 2/. (JGB)
  • There is an increasing trend to locate fossil-fuel electric generating stations in rural areas. These stations emit large quantities of air pollutants capable of causing serious alterations to the surrounding environment. The major phytotoxic air pollutant emitted is sulfur dioxide (SO/sub 2/). The best way to predict the potential impact of new or expanded sources in rural areas would be to develop a computer model to simulate and predict SO/sub 2/ injury to vegetation. The proposed simulator would provide valuable input information for tasks such as site selection and compilation of environmental impact statements. Such a model would also providemore » data to management operators for the regulation of emissions. The model would also aid in our basic understanding of the complex interactions which influence plant susceptibility to air pollution. Input to the model would consist of biological and physical data and the output would include the probability of SO/sub 2/ injuring vegetation near existing or proposed sites. The model would be validated using a field situation. This report presents the results obtained during the first year of the project (August 1, 1977 to July 31, 1978).« less
