Effect of Ozone Toxicity in the Drinking Behavior of Rats

Abstract

To clarify the effects of ozone on behavior, drinking activity was observed continuously in animals exposed to ozone at concentrations of 0.2, 0.4, and 0.8 ppm for 1 wk. Drinking decreased considerably on the first day after onset of exposure. On the first day the suppression rate was calculated to be 28.1%, 69.5%, and 93.1%, for the 0.2 ppm, 0.4 ppm, and 0.8 ppm group, respectively. The suppression of drinking and recovery were dependent on the concentration of ozone.
