The Individual

The oxidant air pollutants, ozone and peroxyacetyl nitrate, are produced in the atmosphere through the interaction of light with nitrogen oxides and gaseous hydrocarbons. These oxidants are phytotoxicants and are known to deleteriously affect plant growth, physiology, and biochemistry. In many instances they induce changes which lead to the death of cells, tissues, organs, and frequently the entire plant. The most obvious damage and biochemical changes are generally observed with leaves.Electron microscopic examination of leaves from bean (Phaseolus vulgaris L.) tobacco (Nicotiana tabacum L.) and cotton (Gossipyum hirsutum L.) fumigated for .5 to 2 hours with 0.3 -1 ppm of the individual oxidants revealed that changes in the ultrastructure of the cells occurred in a sequential fashion with time following the fumigation period. Although occasional cells showed severe damage immediately after fumigation, the most obvious change was an enhanced clarity of the cell membranes.

Five processes controlling the production of soot from gaseous hydrocarbons are distinguished: gas reactions producing radical fragments on which nucleation may begin; nucleation; coagulation; growth; and oxidation. A fundamental model capable of taking into account all these processes is described. The model is applied to the conditions of a practical rocket engine, in which production of soot in the exhaust jet is governed by the rate of pyrolysis of methane in the chamber. Predictions made for these conditions agree with experimental results. The rate controlling processes and key intermediate species are identified.
