A mutagenic effect of ozone on germ cells was suggested by the study of Brinkman et in which female mice exposed to ozone at 0.1-0.2 ppm, 7 h/day, 5 days/week, for 3 weeks before birth, demonstrated a fourfold increase in neonatal mortality. A further report of this study noted increased blepharophimosis and jaw anomalies and a decrease in litter size. An artificial oxidant smog mixture derived from irradiated auto exhaust has also been reported to cause an increase in neonatal mortality in mice. ... 

Certain other types of evidence of plant response are also scarce. We know little about the response by the various crop species to mixtures of air pollutants or to two or more pollutants acting on the plants at different times. Feder et al. (7) report differences in sensitivity of petunia varieties to ozone, sulfur dioxide, PAN, nitrogen dioxide, and irradiated auto exhaust. There seemed, in addition, to be a correlated response to the different gases such that a variety relatively sensitive to one was relatively sensitive to one or more of the others.

Investigations of the potential biol< c actions of a complex photochemical reaction mixture, produced by irradiating mixtures of air and auto exhaust under laboratory conditions that simulated real driving patterns and solar irradiation, were first conducted in the laboratories of the Division of Air Pollution, U.S. Department of Health, Education, and Welfare The effects of both nonirradiated... 

As mentioned previously, decreased voluntary running activity of mice was one of the most sensitive indexes of an effect of ambient photochemical oxidant air pollution or simulated oxidant smog that was produced in the laboratory by irradiating diluted auto-exhaust gases. Whether this effect of the mixtures was due only to ozone or to some other oxidant is not certain. It is plausible to conclude that ozone was the... 

Before ozone - and PAN were identified as specific phytotoxic components of the photochemical complex, researchers used a number of artificial chemical reaction systems to simulate the ambient photochemical-oxidant situation. These efforts involved a number of irradiated and nonirradiated reaction systems unsaturated hydrocarbon-ozone mixtures, unsaturated hydrocarbon-NOx mixtures, and dilute auto exhaust). Most research before 1960 involved one or more of these reaction systems. This research has been well reviewed " - 451.459.488.505 extenslvely covered here. Although the... 

Similar effects were observed with sunlight-irradiated, diluted auto exhaust, which contains NOx (NOx = NO + N02) and a variety of hydrocarbons (HC)... 

Hydrogen peroxide was determined in laboratory irradiated systems, in irradiated air samples containing auto exhaust collected at the entrance of the Lincoln Tunnel, and in ambient air samples at Hoboken, N. J., and...
