title: Studies on the developmental toxicity of ozone: postnatal effects.
abstract: Pregnant rats were exposed to either 0, 1.0, or 1.5 ppm ozone during either mid gestation (Days 9-12) or late gestation (Days 17-20). The dams were allowed to deliver and the early morphological and behavioral development of their pups was monitored. Both exposure regimens transiently reduced neonatal growth rates. The late gestation exposure regimen produced retardations in early reflex development and in open field behavior. Finally, several males from this exposure regimen remained permanently stunted in growth.
