We investigated activity patterns of 17 elementary school students aged 10-12, and 19 high school students aged 13-17, in suburban Los Angeles during the oxidant pollution season. Individuals' relationships between ventilation rate (VR) and heart rat

Twenty-three asthmatic volunteers 19 to 31 yr of age were exposed to 0 (control), 0.2, 0.4, and 0.6 ppm sulfur dioxide (SO2) in random order at 1-wk intervals. Exposures took place in a controlled-environment chamber at 23 degrees C and 85% relative

Eleven generally healthy volunteer subjects were exposed daily to ozone at 0.47 ppm in an attempt to develop adaptation, then reexposed weekly to investigate the persistence of adaptation. Responses were assessed in terms of forced expiratory functio

To investigate short-term health effects of community air pollution directly, we developed a mobile laboratory allowing "blind" exposures of volunteers to polluted ambient air and to purified air at similar temperature and humidity. Subjects (30 asth

The purpose of this study was to determine the effects of 100% oxygen on cell division in lung alveoli of squirrel monkeys. To accomplish this, squirrel monkeys were exposed to 100% oxygen for up to 5 d. Prior to sacrifice, cells preparing to divide

Twenty-five volunteers with chronic obstructive pulmonary disease of mild to moderately severe degree underwent 1-h exposures to 0.12 ppm ozone (O2) in purified air with intermittent mild exercise. Their responses were assessed in terms of forced exp

To investigate whether ambient air quality standards for ozone adequately protect high-risk populations, we assessed pulmonary and biochemical responses of 22 asthmatic volunteers to 2-hour controlled exposures to ozone at concentrations approximatin
