Quantitative measurements of ventilatory functions (flow resistance of the lung plus thorax, respiratory rate and tidal volume) of guinea pigs were done before, during and following 2-hour exposure to SO_2, NO_2 and O_3. Although, apart from the degree of the cahange, these gases caused similary an increase in the flow resistance of the animals, striking difference in the direction of the change in the respiratory rate caused by the exposure was observed between these gases. SO_2 caused a decrease in the respiratory rate while the other two gases an increase. Also the tidal volume generally tended to change in the opposite direction. Based on these results, the possible difference in the change of mechanical behavior of the respiratory system and, in turn, the difference in the area of the lungs where the gases could reach were assumed between exposures to these gases.
