How ozone formed
Nettet14. jun. 2024 · Ozone is a gas composed of three atoms of oxygen. Ozone occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or … Nettet6. nov. 2024 · Ozone is formed in the atmosphere through chemical reactions between pollutants emitted from vehicles, factories and other industrial sources, fossil fuels, combustion, consumer products, evaporation of paints, and many other sources. Hydrocarbons and nitrogen oxide gases react in the presence of sunlight to form ozone.

This theory, which describes how sunlight …
NettetMost of this ozone is created as a byproduct of human-created photochemical smog. This build up of ozone is toxic to organisms living at the Earth's surface. The last row in Table 1.1 lists a group of compound which plays an essential role for the ozone layer and the climate on Earth: the halocarbons. NettetHealth effects depend on ozone precursors, which is a group of pollutants, primarily generated during the combustion of fossil fuels. Ground-level ozone is created by nitrous oxides reacting with organic compounds in the presence of sunlight. There are many man-made sources of these organic compounds including vehicle and industrial emissions, …
