When smoke and fog combine in the air it causes a type of air pollution called?

Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. In the 1950s a new type of smog, known as Photochemical Smog, was first described.

What is the combination of smoke and fog called?

The term “smog” was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in cities today. Today, most of the smog we see is photochemical smog.

Which pollutants are responsible for the cause of smog?

This kind of visible air pollution is composed of nitrogen oxides, sulphur oxides, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.

What type of reaction creates smog?

Smog is formed when sunlight interacts with hydrocarbons and nitrogen oxides released into the air by cars and power plants. A highly reactive compound of oxygen and hydrogen called a hydroxyl radical kick starts that reaction.

Who gave the term smog?

London, England, physician Harold Des Veaux coined the word smog in 1905 to describe natural fog contaminated by smoke: smoke + fog yielded smog.

What is the main component of city smog?

Smog and poor air quality is a pressing environmental problem, particularly for large metropolitan cities. Smog, the primary constituent of which is ground level ozone, is formed by a chemical reaction of carbon monoxide, nitrogen oxides, VOCs, and heat from sunlight.

Which of the following is the main component of smog?

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.

What are the two 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 is a CLAG?

Definition of clag (Entry 2 of 2) dialectal, British. : a clot or lump especially of dirt or snow.

What does smog mean?

: 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.

Do 25 year old cars need smog?

classic cars do qualify for a smog exemption in California. By definition, a classic or antique car is any vehicle that is 25 years or more old. Since cars built before 1975 are exempt from the California smog certification program, owners are not required to have their vehicles checked for smog-producing emissions.

Is smog a word?

Yes, smogs is in the scrabble dictionary.

Why is smog dangerous?

Smog can irritate your eyes, nose and throat. Or it can worsen existing heart and lung problems or perhaps cause lung cancer with regular long-term exposure. It also results in early death. Studies on ozone show that once it gets into your lungs, it can continue to cause damage even when you feel fine.

What state has the worst smog?

Air pollution in California Los Angeles has the most contaminated air in the country.

How can you protect yourself from smog?

How to protect yourself against smog

  1. Check the AQHI in your community.
  2. Limit strenuous outdoor activities, when the AQHI is high.
  3. Avoid exercising near areas of heavy traffic.

What is smog and its harmful effects?

Smog is a form of air pollution that mainly consists of ozone, along with harmful substances like sulphur dioxide, nitrogen dioxide, carbon monoxide and PM10s, which can find their way deep into our lungs. Smog can be caused by: Large amounts of coal-burning in an area.

How does smog harm the environment?

Smog is made up of a combination of air pollutants that can compromise human health, harm the environment, and even cause property damage. The ozone in smog also inhibits plant growth and can cause widespread damage to crops and forests.

What are the harmful effects of smog Class 8?

The carbon particles, nitrogen oxides and sulphur dioxide of smoke combine with the condensed water vapour called fog to form smog. Smog causes cough and aggravates (makes worse) asthma and other lung diseases, especially in children.

What are some areas where smog is bad?
