What is the main source of pollutants in photochemical smog quizlet?

What is the main source of pollutants in photochemical smog quizlet?

Photochemical smog is a mixture of about one hundred primary and secondary pollutants formed under the influence of sunlight. Ozone is the main pollutant. Precipitation cleans the air and winds disperse the smog.

Which pollutants is the major contributor to photochemical smog?

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

What is the main pollutant in smog?

These primary pollutants include nitrogen oxides, particularly nitric oxide (NO) and nitrogen dioxide (NO2), and volatile organic compounds. The relevant secondary pollutants include peroxylacyl nitrates (PAN), tropospheric ozone, and aldehydes.

What are the main sources of the pollutant?

There are four main types of air pollution 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 is the major source of photochemical smog in the United States?

Formation. Photochemical smog forms from a complex process, however the source of it is quite apparent. The largest contributor is automobiles, while coal-fired power plants and some other power plants also produce the necessary pollutants to facilitate its production.

What are the main causes of smog quizlet?

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

Which of the following pollutants are responsible for the causes of smog?

2. Which of the following pollutants are responsible for the cause of SMOG? Answer: (c) Both incinerators and emissions from vehicles.

Is formaldehyde a component of photochemical smog?

The common components of photochemical smog are ozone, nitric oxide, acrolein, formaldehyde and peroxyacetyl nitrate (PAN).

Which of the following is a secondary pollutant and major component of photochemical smog?

Photochemical smog is made up of various secondary pollutants like ozone, peroxyacyl nitrates (PANs), and nitric acid (seen in Figure 2). Different types of secondary pollutants include: Ozone (O3) Sulfuric acid and nitric acid (component of acid rain)

What are the main toxic pollutants?

Toxic, or hazardous, air pollutants cause or are suspected of causing cancer, birth defects, or other serious harms. They can be gases, like hydrogen chloride, benzene or toluene, dioxin, or compounds like asbestos, or elements such as cadmium, mercury, and chromium.

What are the different types of air pollutants?

Air Pollutants

• Carbon Monoxide.
• Lead.
• Nitrogen Oxides.
• Ozone.
• Particulate Matter.
• Sulfur Dioxide.
• Other Air Pollutants.

Which of the following pollutants are responsible for the cause of smog Mcq?

What are the health effects of smog?

Effects of Smog. Smog causes health problems affecting the respiratory system. There is an increase in Asthma, Emphysema, Chronic Bronchitis, Chronic Obstructive Pulmonary Disease (COPD)and lung cancer. It causes eye irritation. It breaks down natural immunity of the body, and makes it prone to colds and lung infections.

What is an example of a primary pollutant?

Sulfur Oxides. Sulfur oxides are formed when fuels having sulfur undergoes combustion.

Nitrogen Oxides. Nitrogen oxides are poisonous and highly reactive gases that are formed after burning fuels at high temperatures.

Carbon Monoxide.

Volcanic Organic Compounds.

What are the primary and secondary air pollutants>?

Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

How does photochemical smog form?

Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere . It is visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities. [2]
