Which of the following contributes to smog?

What contributes to smog?

Air pollution emitted from transportation contributes to smog, and to poor air quality, which has negative impacts on the health and welfare of U.S. citizens. Pollutants that contribute to poor air quality include particulate matter (PM), nitrogen oxides (NOx), and volatile organic compounds (VOCs).

What are three sources of smog?

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. natural sources – such as wind-blown dust, wildfires, and volcanoes.

What is the biggest contributor to smog?

Transportation emissions

The major culprits from transportation sources are carbon monoxide (CO), nitrogen oxides (NO and NO2), volatile organic compounds, and hydrocarbons (hydrocarbons are the main component of petroleum fuels such as gasoline and diesel fuel).

What causes smog quizlet?

What causes smog? Smog is mostly caused by action of sunlight on a mixture of hydrocarbons &amp, oxides of Nitrogen.

What causes industrial smog?

Industrial smog typically exists in urban areas where factories burn fossil fuels such as coal, which creates smoke and sulfur dioxide that mix with fog droplets to create a thick blanket of haze close to the ground.

What causes smog in cities?

Ground level ozone is created when sunlight reacts with certain chemicals that come from sources of burning fossil fuels, such as factories or car exhaust. When particles in the air combine with ozone, they create smog. Smog is a type of air pollution that looks like smoky fog and makes it difficult to see.

What are examples of smog?

Smog is a mix of fog and smoke, or a layer of polluted air. An example of smog is a low-lying yellow or brown layer of air. (archaic) A noxious mixture of fog and smoke.

How many types of smog are there?

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 causes smog in California?

Ozone is one of the major constituents of smog and is formed in the atmosphere by complex reactions with chemicals that are directly emitted from motor vehicles and other combustion sources.


Pollutant Examples of Sources
Nitrogen Dioxide (NO2) See carbon monoxide sources

Which of the following pollutant is the major contributor to photochemical smog?

Option 2 is the correct answer: Ozone is the major contributor to photochemical smog.

What are the causes and effects of smog?

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 quizlet?

-Smog: a poisonous mixture of smoke, aire, and other pollutants. -need: emissions, warmth/sunlight, and no air movement.

What are the major causes of smog and acid rain?

What causes smog and acid rain? … Photochemical smog is caused by nitrogen oxides combing with sunlight and other pollutants. Acid rain is caused by sulfur oxides and nitrogen oxides combining with water.

What type of pollution is smog quizlet?

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 causes sulfuric 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 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. Sinha’s paper focuses on this hydroxyl radical, known as OH.

What is caused by sulphur smog?

Sulfurous smog, also known as London smog, develops due to high concentration of sulfur oxides in the air. This gas is a serious air pollutant, causing irritation to human eyes, nose and lungs. It is released into the air by sulfur-bearing fossil fuels like coal.

How is smog formed Class 9?

Smog is formed when there is heavy auto mobile exhaust and industrial emission. These emissions are dispersed differently over a region depending upon its geographical location, tree cover, temperature and winds.

What type of colloids is smog?

Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color. Many familiar substances, including butter, milk, cream, aerosols (fog, smog, smoke), asphalt, inks, paints, glues, and sea foam are colloids.

What are effects of smog?

Ground-level ozone (a key component of smog) is associated with many health problems, such as diminished lung function, increased hospital admissions and emergency room visits for asthma, and increases in premature deaths.

Which of following disaster is related to smog?

Great Smog of London, lethal smog that covered the city of London for five days (December 5–9) in 1952, caused by a combination of industrial pollution and high-pressure weather conditions. This combination of smoke and fog brought the city to a near standstill and resulted in thousands of deaths.

How is smog formed 12?

The word ‘smog’ is a blend of smoke and fog. Smog is formed when the smoke particles combine with the already occurring fog.

What is smog class8?

Smog: This is a thick fog-like layer in the atmosphere, especially during winters, made up of fog and smoke. • Sulphur dioxide is mainly produced by burning fuels such as coal. It causes respiratory problems, including permanent lung damage.

What are the 10 causes of pollution?

  • Open Burning of Garbage Waste. …
  • Construction and Demolition.

What are the main causes of air pollution in Los Angeles?

Motor vehicles are the single largest source of carbon monoxide emissions. Nationwide, cars and trucks contribute to more than 50% of all emissions, in cities like Los Angeles, where traffic density is high, their contribution is even greater. Other major sources of carbon monoxide include non-road equipment and fires.

How did LA get rid of smog?

But the air quality in Los Angeles had improved, and that was largely due to the Clean Air Act, which helped lower emissions from cars and industry.

Which of the following is the current major contributor to lead their pollution?
