Oxidation of photochemically reactive VOCs forms highly reactive chemical species known as free radicals, which are capable of converting NO to NO2 without destruction of O3.

Impacts of High Levels of Ozone

Anything that is susceptible to oxidation is a potential target for the adverse effects of O3.

Human Health:

- Reduced lung function (cough, chest pain)
- Decline in lung capacity

Crop Damage:
