What is SMOG and how is it caused?
smog = Smoke + fog it is created when the fog mixes with the pollution in air. Smog looks almost like fog, but is harmful if inhaled for a sufficient period of time.

Is smog a gas?
Smog is actually a collection of toxic gases. Usually smog is used in reference to toxic gases produce by vehicles or other forms of energy production i.e coal burning.

Why is smog bad?
smog is a mixture of poison gasses and burnt fossil fuels. If ingested for a long it can make you sick. If inhailed it can damage you lungs and has been known to cause asthma.… It chokes out the oxygen and replaces it with dangerous gasses. It can makes birds sick and pass on the chemicals found in the cloud of smog to the animal that eats that bird. Known as Bioapliphication. This can cause a decrease in the bird pop. and cause a decrease in it's ecosystem. The word smog means smoke and fog smog is cuased by ground-level ozone. smog is most likely to occur farther away from the source of its pollutants. This happens because the chemical reaction takes time and the wind causes the smog to be swept away in the wind. (MORE)

What is smog?
Answer 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 come from burning of petroleum-based fuels such as gasoline. Other smog-formers, volatile organic compounds, are found in products such as paints and solvents. Smog can harm health, damage the environment and cause poor visibility. Smog is a combination of fog and pollution. The common cause of a widespread thick fog is a temperature inversion. If there is a significant source of pollution under the inversion, it gets trapped along with the fog. The famous London pea-soupers were produced by mixing fog with the smoke from several million open hearths burning coal. The coal used contained a large amount of sulphur, so the smoke contained lots of sulphur dioxide. This nasty yellow tinged fog killed hundreds of people in the 1950s; the resulting public outcry led to a ban on burning this type of coal. London still gets very thick fog at times, but it doesn't hurt the lungs any more. Los Angeles has an even bigger problem. Their pollution source is car exhaust emissions, especially oxides of nitrogen. . The photo-actinic effect of their continual strong sunlight makes the pollution worse. Banning cars is politically impossible, so the state of California has done the next best thing, with the strictest emission standards in the world. The problems caused by smog vary according to the pollution type. They include : Lung damage from bronchitis to cancer; severe eye irritation; blackened buildings; smelly hair and clothes. (MORE)

What causes smog?
Smog is caused by many factors. The smog that enters the atmosphere consists of over 100 chemicals, many coming from different sources..
Particulates present in smog include …carbon monoxide, dirt, soot, dust, and ozone. To really create the smog effect, sunlight, hydrocarbons, and nitrogen oxides have to mix together..
Major producers of smog include automobiles, fires, waste treatment, oil production, industrial solvents, paints, and coatings..
Car engines, especially diesel engines, as well as gas stations that allow gas to be leaked out are huge contributors to the smog problem. Gas vapor that gets away from gas pumps contributes to the hydrocarbons needed to form smog. Diesel engines emit particles of soot that enter the atmosphere..
Today, the smog problems created by cars are becoming increasingly severe. As gas prices decline, consumers are buying cars that use more gas, and hence pollute the atmosphere to a greater extent. (MORE)

Smog in driving?
Carbon dioxide is produced when internal combustion engine give off exhaust. When it mixes with moisture in the air, it becomes a substance called smog.

What was the London smog?
The Great London Smog (SMoke + fOG) was the result of coal smokefrom fired heating during an unusual cold period combining with theheavy fogs of London. Although smog was not …uncommon in London thiswas an unprecedented event, it lasted from Friday 5 December toTuesday 9 December 1952. The coal smoke contained sulfur dioxideans a well as organic (coal tar) compounds which made the mixtureacidic and resulted in breathing problems for many. About 4,000people were known to have died as a result of the fog, thisestimate could be considerably loweer than the actual number. (MORE)

Why is smog called smog?
Smog is a slang word blending smoke and Fog. Could be related to certain types of fires ( oil refineries, yecch!) or more stable like-pollution from chemical industries. I hav…e heard the term Smog Hog applied to a number of old and fuel -inefficient vehicles. It was applied to some piston-engine trainers by the airmen, and in a differnt sort of lift- derisively to the huge cranes they had at Koppers Koke in Hudson County . These had modern truss booms, were live steam and coke-fired and ran on paralell sets of tracks- l8 foot gauge.l My guess they weighed as much as a full-sized locomotive such as the GG-L. I have heard these cranes derisively called Smog Hogs, sadly they are extinct. They were made byLink Belt and called, officially, Broad Gauge locomotive cranes. (MORE)

What was London smog?
It no longer exists/happens but in the days when London houses used coal fires to heat homes, the coal smoke mixed with normal fog to produce what was called "smog" (smoke… and fog). It was very thick and very bad for health. London no longer has "smog" events because it no longer allows chimneys to emit smoke. (MORE)
