Etymology
The phrase "lo strato di ozono" comes from Italian, where "strato" means 'layer' and "ozono" refers to ozone, a molecule composed of three oxygen atoms. The term ozone itself derives from the Greek word 'ozein', meaning 'to smell', because ozone has a distinctive sharp odor that was first noticed during electrical discharges.
