Ozone Pollution Alters Olfaction and Behavior of Pollinators.

Concentration of air pollutants, particularly ozone (O), has dramatically increased since pre-industrial times in the troposphere. Due to the strong oxidative potential of O, negative effects on both emission and lifetime in the atmosphere of plant volatile organic compounds (VOCs) have already been highlighted. VOCs alteration by O may potentially affect the attraction of pollinators that rely on these chemical signals.
