Voc (volatile organic compounds) + nox + heat + sunlight = ozone. Can be pollutant if formed on ground level (bad) but contributes to the protection from uv radiation high in the stratosphere (good) Bad ozone is formed summertime and its production also depends on the time of day (e. g. highest in afternoon), season and climate (e. g. Bad ozone is formed summertime and its production also depends on the time of day (e. g. highest in afternoon), season and climate (e. g. higher levels in mexico city and l. a. compared to. Transported over long distances, thus rural areas are equally affected as urban areas and as well they can travel from south (warmer) to the north (colder) It does not dissolve in upper levels of our airways but further down and closer to our lungs and execute damage.
