Smog Affects More Than 158 Million Americans in 10 States
Well over half of all people living in 10 of the United States' 11 most populous states"more than 158 million Americans"live in areas where the smog is so bad that pollution levels ...
smog - a dense, discolored radiation fog containing large quanities of soot, ash, and gaseous pollutants such as sulfur dioxide and carbon dioxide, responsible for human respiratory ailments.
Smog
Originally a mixture of smoke and fog. Now, air pollution produced by the reaction of hydrocarbons and nitrogen oxides in the presence of sunlight. It is mainly made up of ozone.
smog: Smog is ground level ozone and particulate matter formed by burning fuels on hot, sunny days.
space shuttle: One of the NASA spacecraft we use to reach Earth's orbit on a regular basis.
Smog - This is a term used to describe a mixture of smoke and fog. Smog occurs when high concentrations of moisture is combined with smoke (often containing oxides of sulfur and nitrogen) in the presence of high temperatures or thermal inversions ...
Smog. Hazy, polluted air caused by the combination of ultraviolet rays from the sun and automobile and industrial emissions in the atmosphere ...
Smog: Air pollution typically associated with oxidants. (see Photochemical Smog)
Smoke: Particles suspended in air after incomplete combustion.
Soft Detergents: Cleaning agents that break down in nature.
Smog (photochemical smog): Literally a contraction of "smoke" and "fog"; the colloquial term used for photochemical fog, which includes ozone and numerous other contaminants. Smog is usually adds a brownish haze to the atmosphere.
Smog: Air pollution caused by chemical reactions of various pollutants emitted from different sources. Ozone is one of the main ingredients of smog, and it can harm people’s health.
Smog - a term used to describe many air pollution problems. Smog is a contraction of smoke and fog; it describes the irritating stagnant haze resulting from the sun's effect on pollutants in the air. Also known as ground-level ozone.
Smog
Air pollution consisting of smoke and fog, which occurs in large urban and industrial areas and is mainly caused by the action of sunlight on burned fuels, mostly from car exhausts.
Smog - A mixture of pollutants, principally ground-level ozone, produced by chemical reactions in the air involving smog-forming chemicals. A major portion of smog-formers comes from burning of petroleum-based fuels such as gasoline.
Smog
Air pollution associated with oxidants. (See: photochemical smog.)(1) ...
Smog is a mixture of smoke, chemical pollutants and fog (dispersed water droplets). Smog hit many UK cities in the 1950s and early 1960s, killing nearly 5000 elderly people.
Smog: A combination of smoke and other particulates, ozone, hydrocarbons, nitrogen oxides, and other chemically reactive compounds which, under certain conditions of weather and sunlight, ...
smog : Dust, smoke, or chemical fumes that pollute the air and make hazy, unhealthy conditions (literally, the word is a blend of smoke and fog).
Photochemical Smog- Air pollution caused by chemical reactions of various pollutants emitted from different sources.
P photochemical smog
Definition (english only)
A combination of fog and chemicals that come from automobile and factory emissions and is acted upon by the action of the sun.
Nitric oxide is a precursor of ground-level ozone pollution, or smog. Nitrogen Oxide (NOx) The result of photochemical reactions of nitric oxide in ambient air.
ozone Pungent, colorless, toxic gas that is the major component of smog. It is formed when sunlight triggers chemical reactions involving hydrocarbons and oxides of nitrogen.
Smog A type of air pollution that occurs when various types of particle elements contaminating the air have a chemical reaction with sunlight.
Ozone reacts directly with some hydrocarbons such as aldehydes and thus begins their removal from the air, but the products of ozonolysis are themselves key components of smog.
In the troposphere, it is created both naturally and by photochemical reactions involving gases resulting from human activities (photochemical smog). In high concentrations, tropospheric ozone can be harmful to a wide range of living organisms.
Fine liquid or solid particles such as dust, smoke, mist, fumes, or smog, found in air or emissions. 2.
A collective term for some of the primary constituents of photochemical smog.
Oxidation Pond
A man-made (anthropogenic) body of water in which bacteria, used most frequently with other waste-treatment processes, consume waste; a sewage lagoon.
Nitrogen Oxide (NOx): The result of photochemical reactions of nitric oxide in ambient air; major component of photochemical smog.
It is a major component of photochemical smog, a product of combustion from transportation and stationary sources, and a major contributor to the formation of ozone in the lower atmosphere and to acid deposition.
photochemical oxidants Air pollutants formed by the action of sunlight on oxides of nitrogen and hydrocarbons. photochemical smog Air pollution caused by chemical reactions of various pollutants emitted from different sources.
Oxidant - A substance containing oxygen that reacts chemically in air to produce a new substance; the primary ingredient of photochemical smog.
- P -
Paraquat - A standard herbicide used to kill various types of crops, including marijuana.
NOx is a greenhouse gas and is an ingredient of acid rain and smog.
Non-renewable Energy Resources Energy resources that cannot be restored or replenished by natural processes and therefore are depleted through use.
Volatile Organic Compound: Any organic compound which evaporates readily to the atmosphere. VOCs contribute significantly to photochemical smog production and certain health problems.
Nitrogen Oxides (NOX): Nitrogen compounds such as NO and NO2 produced by combustion. They help to from ozone and photochemical smog.
NO2: Nitrogen Dioxide

can have a significant impact on our quality of life. Many communities across the nation have a "serious" air pollution problem. This designation results mainly from ground-level ozone, the main component of what is commonly referred to as "smog." ...
Organic liquids, including many common solvents, which readily evaporate at temperatures normally found at ground surface and at shallow depths. They take part in atmospheric photochemical (sun-driven) reactions to produce smog.
Nitrogen Oxide (N2O) is a colourless gas with a sweet odour which is used as a weak anaesthetic ('laughing gas'). Nitrogen Dioxide (NO2) is a reddish-brown toxic gas which is one of the products of vehicle combustion and an active part of smog.
