Preexposure to ozone blocks the antigen-induced late asthmatic response of the canine peripheral airways
Turner, CR; Kleeberger, SR; Spannhake, EW
1,989
The influence of exposure of the airways to ozone on acute allergic responsiveness has been investigated in several species. Little is known, however, about the effect of this environmental pollutant on the late asthmatic response (LAR) in animals in which it is exhibited. The purpose of this study was to evaluate this...

1,989
In Shenandoah National Park, O3 monitoring data were characterized and attempts were made to relate O3 concentration levels to visible foliar injury observed for five plant species surveyed. Foliar injury for three species increased with elevation. The 24-h monthly mean O3 concentrations tended to increase with elevati...

Lung function and chronic exposure to air pollution: a cross-sectional analysis of NHANES II
Schwartz, J

The effect of air pollution on lung function in children and youths ages 6-24 years was examined, after controlling for age, height, race, sex, body mass, cigarette smoking, and respiratory symptoms. Forced vital capacity (FVC), forced expiratory volume at 1 sec (FEV1), and peak expiratory flow all showed statistically...

The activity of superoxide dismutase was investigated in needles of spruce trees. To obtain maximum activity, needles were homogenized in the presence of Triton X-100 and polyvinylpyrrolidone. Superoxide dismutase activity was measured in dialyzed extracts with a modified epinephrine assay (HP Misra, I Fridovich [1972]...

Unattenuated structural and biochemical alterations in the rat lung during functional adaptation to ozone
Tepper, JS; Costa, DL; Lehmann, JR; Weber, MF; Hatch, GE
1,989
Acute ozone (O3) exposure in humans produces changes in pulmonary function that attenuate with repeated exposure. This phenomenon, termed adaptation, has been produced in unanesthetized rats. Rats exposed to O3 (0, 0.35, 0.5, or 1.0 ppm) for 2.25 h for 5 consecutive days showed an increased frequency of breathing and a...

The effect of oxidant exposure on the immediate airway response to immunologic challenge is controversial. We investigated the response of canine peripheral airways to antigen aerosol, 1-3 h and 24 h after a 5-min exposure to 1 ppm ozone.

A UV-photofragmentation/laser-induced fluorescence sensor for the atmospheric detection of HONO
Rodgers, MO; Davis, DD
1,989
#An in situ laser-based detection system for measuring atmospheric HONO has been built and tested. This spectroscopic selective system has been tested for numerous chemical interferences. The results from these tests indicate that down to the tens of parts per trillion HONO concentration range no significant problems w...
