An ozone machine is a device that generates ozone, which is a naturally occurring gas in the earth’s atmosphere that is composed of three oxygen atoms (O3). Often referred to as an ozone generator, an ozone machine is commonly used to improve the air quality of the interior of a room ...
Ozone is a naturally occurring substance which was first made in the laboratory in 1839 byGerman scientist Christian Friedrich Schönbein(1840a, 1840b). Schönbein was interest- ed in discovering the origin of the odour produced by certain chemical and electrical processes. What is Ozonosphere in...
Ozone is a highly reactive molecule - a naturally occurring cleanser, killing bacteria, germs, viruses, and other microbes up to 50 times more effectively than chlorine bleach. Because ozone is generated on location, it also eliminates additional costs and environmental impacts of storage and distrib...

The greenhouse effect is a naturally occurring process in which the earth’s surface and atmosphere are heated. It results from the fact that certain gases, such as carbon dioxide(二氧化碳),water vapor, and methane(甲烷),are able to change the energy balance of the planet by being able to ...
where up to 60 percent of the total overhead amount of ozone (known as the column ozone) disappears during some periods of the Antarctic spring (September through November). This phenomenon, which has been occurring only since the early 1980s, is known as the Antarctic ozone hole. In the ...

p-Anisaldehyde (4-methoxybenzenaldehyde, C8H8O2) is a naturally occurring fragrant phenolic compound that is soluble in acetone. The compound occurs in many plant species including anise, Pimpinella anisum L.; cumin, Cuminum cyminum L.; fennel, Foeniculum vulgare Miller; and garlic, Allium sati...
The researchers also estimated the excessive admission risk for cardiovascular disease associated with ozone concentrations at or above the WHO air quality guideline (100 µg/m3) compared to levels below 70 μg/m3. Ozone levels below 70 μg/m3are mostly naturally occurring and not due to huma...
(O2) interacts with solar radiation and breaks apart into two oxygen atoms; each atom then joins up with an oxygen molecule. The ozone molecule is unstable, so it soon decays to again form molecular oxygen. This cyclic process absorbs radiation and is constantly occurring in the upper reaches...
