Where does the ozone originate from?

Answer 1

Ozone comes from: # oxygen molecules being broken apart into atoms (by UV-C or electrical corona) and some combining with oxygen molecules to make ozone. # oxygen molecules being broken apart into atoms, some carried briefly by nitrogen molecules, then combining with oxygen molecules to make ozone. # decay of trioxidane, produced by various organisms internal defense mechanisms to fight off attack (infection). Best to review the link below at Wikipedia. Ozone in the stratosphere is produced by UV-C dissociating oxygen molecules, some of which recombine as ozone. Ozone in the troposphere is produced by NOx, VOC, and visible light of violet or more energetic wavelength. Some ozone is produced directly by lightning, waterfalls, industrial / commercial processes, and some chemical processes.

Answer 2

Ozone forms when monatomic oxygen bonds with diatomic (normal) oxygen. Nitrogen can act as an intermediary, briefly "carrying" the monatomic oxygen to some other place... perhaps oxygen, perhaps water vapor (to make H2O2). Monatomic oxygen is formed when UV light of 215nm (or more energetic) strikes O2. Also, an electron with enough energy can also break apart O2, such as lightning and corona (in an ozone generator or other electrical equipment). In the ozone layer, the driver for ozone production is UV from our Sun, with a smaller contribution from cosmic rays and other charged particles arriving on the solar wind.

Answer 3

Ground level ozone has several potential sources:

* From the interaction of hydrocarbons and nitrogen oxides in the presence of ultraviolet light during the creation of photochemical smog * From downwashing of stratospheric ozone as winds blow over tall mountains * From electrical discharges like lightning

Answer 4

Most of it comes from photoproduction in smog; namely NOx, VOC, and violet or more energetic light from the Sun. Most smog comes from consuming fossil fuels by combustion.

Some (<< 1%) comes from processes that use ozone, but were too cheap to buy an ozone destruct unit, or did not bother to collect all their offgas.

Some (< 2%) comes from electric power lines / substations.

Some (< 20%) comes from natural ionization, cosmic rays, the normal background radiation endemic to the area of interest, and lightning.

A considerable amount of tropospheric ozone is the result of down washing of stratospheric ozone by winds passing over mountains. In Alberta this is the principle source of high levels of ambient ozone.

Answer 5

Ozone forms in all layers of the atmosphere. It is near zero concentration at the top of the exosphere, and the bottom of the troposphere. It has its highest concentration, and most of it is found, in the lower stratosphere. This concentrated region is called the "ozone layer". Ozone near Earth's surface is formed by static electricity, air pollution, and more. the ozone layer is formed between the thermosphere and the mesosphere

Answer 6

Chlorine in the ozone layer comes from CFC's. Naturally it comes from volcanoes.

Answer 7

The ground level ozone is formed by various sources. Vehicle exhaust and lightening are two of the sources.
