Previous research has reported that the lung development of animals exposed to oxidant gases early in life might be impaired, or that developing lungs might be more susceptible than adult lungs to inhaled toxicants. Dr. Mauderly and colleagues at the Lovelace Biomedical and Environmental Research Institute examined the age-related differences in the physiological responses of rats to inhaled automotive emissions. The younger group was exposed during gestation and through the age of six months, while the older group was exposed between the age of six and twelve months.

Dr. Drechsler-Parks and colleagues at the Institute of Environmental Stress sought to examine the effects of nitrogen dioxide, ozone, and peroxyacetyl nitrate on metabolic and pulmonary function. Because it is possible that two or more pollutants could interact in ambient air and cause effects that could not be predicted from the effects observed with the individual pollutants, the investigators examined varying levels of different pollutants in 32 non-smoking men and women (8 men and 8 women 18-26 years of age and 8 men and 8 women 51-76 years of age).

Acute hemolytic anemia is associated with a deficiency in glucose 6-phosphate dehydrogenase (G6PD), an X-linked inheritable characteristic. Hemolytic anemia is thought to be caused by a depletion of glutathione and other reducing compounds in red blood cells. Dr. Amoruso and colleagues sought to experimentally test the Calabrese hypothesis, which suggests that G6PD-deficient individuals may be at an increased risk of hemolysis during exposure to low levels of oxidants such as ozone.
