Outbred CD 1 mice were either not exposed (control group) or exposed to ozone (O3) (0.3, 0.6, or 0.9 ppm), during foetal and neonatal life until the time of weaning (postnatal day (PND) 26). On PND 70 the subjects were tested for handedness using a paw preference task assessing both the animals' capability to reach a food pellet in a feeding tube and the individual preference for the use of one of the other forepaw. O3 exposure did not affect the animals' capability to learn the task but caused changes in handedness. Specifically, females exposed to the intermediate O3 concentration showed a reduced preference for the right paw than both their same-sex controls and 0.6 ppm males. On PND 100, mice underwent a hot plate test after IP treatment by either saline or morphine HCl (10 mg/kg). The results were generally in the direction of reduced drug sensitivity after exposure to the highest concentration. The evidence for this effect was more robust in the case of an organised avoidance response (wall-rearing) than in the case of a reflexive response (limb withdrawal); in the case of the former, latency data showed an effect on both males and females while frequency data showed an effect only in females. Overall, the O3 effects are suggestive of subtle CNS changes affecting mouse behavioural responses.
