London, England, physician Harold Des Veaux coined the word smog in 1905 to describe natural fog contaminated by smoke: smoke + fog yielded smog.
How did the word smog get its name?
In 1905, the English term smog was coined by Dr. Henry Antoine Des Voeux in his paper, “Fog and Smoke” for a meeting of the Public Health Congress in London[1]. He combined two words, smoke and fog, to create a new term smog.
Who first discovered smog?
Dr. Arie Haagen-Smit
That’s when Dr. Arie Haagen-Smit discovered the nature and causes of photochemical smog. He made the discovery while on a one-year leave of absence from Caltech, where he was a bioorganic chemistry professor.
Why is it called London smog?
London had experienced these types of smog before. They were called “pea-soupers” due to their yellowish-brown appearance. Today, pea-soupers are known as sulphurous smog or “London smog”. These result from a high concentration of sulphur oxides (SOx) in the atmosphere from fossil fuels high in sulphur, such as coal.
Where was smog invented?
China was the first country to commercialize transgenic plants, introducing a virus-resistant tobacco in 1992. In 1994, Calgene attained approval to commercially release the Flavr Savr tomato, the first genetically modified food.

What is the full meaning of smog?
: a fog made heavier and darker by smoke and chemical fumes. also : a photochemical haze caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen especially from automobile exhaust.
Who is the father of pollution?
Arie Jan Haagen-Smit (December 22, 1900 in Utrecht – March 17, 1977 in Pasadena, California) was a Dutch chemist. He is best known for linking the smog in Southern California to automobiles and is therefore known by many as the “father” of air pollution control.
Is smog human made?
Smog forms when pollutants are released into the air. The pollutants are formed both naturally and by humans, however, the human-induced pollutants are of most concern due to the magnitude of pollutants produced by the burning and extraction of fossil fuels, which are known to cause extreme health effects.
What is smog made of?
Smog, formed mainly above urban centres, is composed mainly of tropospheric ozone (O3); primary particulate matter such as pollen and dust; and secondary particulate matter such as sulphur oxides, volatile organic compounds, nitrogen oxides (NOx) and ammonia gas.
Why is England so GREY?
Britain is particularly cloudy because it’s located in the Warm Gulfstream. The heat necessary to evaporate all that water was absorbed off the African American coast, and then transported along with the water. The air above Britain, on the other hand, is quite often coming from the polar areas and thus much colder.
Did the Queen really walk in the smog?
Yes, fact-checking The Crown confirms that the Great Smog was indeed a real event in 1952.
How many died in London smog?
Impacts of the smog
About 4,000 people were known to have died as a result of the fog, but it could be many more.
What are 3 sources of smog?
Types of Sources
mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.
What are 2 main causes of smog?
The main causes of smog
Smog is formed by mixing air with pollutants and exhaust gases resulting from human activities. The factors which are responsible for this include factories, an increasing number of cars, burning coal, wood and other solid fuels in stoves.
What country suffers from smog?

What does smog mean in California?
Smog checks are state-sponsored programs designed to identify cars that release excessive tailpipe emissions. Instituted shortly after the Clean Air Act in 1966, these programs aim to reduce air pollution and vehicle emissions, and improve regional air quality to comply with local emissions regulations.
Why is smog so important?
When inhaled, smog irritates our airways, increasing our risk of serious heart and lung diseases. These health risks are why many cities monitor smog levels. On a high ozone-alert day, for example, your eyes and throat may burn, and you may cough and wheeze.
What does smog look like?
Smog is a visible form of air pollution that often appears as a thick haze. Look toward the horizon during daylight hours, and you can see how much smog is in the air. High concentrations of nitrogen oxides will often give the air a brownish tint.
What are the 2 types of smog?
At least two distinct types of smog are recognized: sulfurous smog and photochemical smog. Sulfurous smog, which is also called “London smog,” results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal.
What are the root words of smog?
Smog is a great example of a portmanteau, a word formed by combining two other words into one: it comes from smoke and fog.
