What are primary and secondary air pollutants?

Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.

What are secondary air pollutants?

Secondary pollutants are pollutants which form in the atmosphere. These pollutants are not emitted directly from a source (like vehicles or power plants). Different types of secondary pollutants include: Ozone (O3) Sulfuric acid and nitric acid (component of acid rain)

Is acid rain a primary or secondary pollutant?

Secondary pollutant form when primary pollutants emitted directly from a combustion process react in the atmosphere. Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

Is co2 secondary pollutant?

Carbon Monoxide (CO) Most of the carbon monoxide pollution comes from burning fossil fuels in vehicles, factories, and power plants, but another major source is from burning wood or crop waste. Secondary pollutants like ozone and carbon dioxide (CO2), a greenhouse gas, come from carbon monoxide.

Is NO2 primary or secondary pollutant?

It’s mainly produced by road traffic and energy production. While NO2 is a primary pollutant, it is also a contributing component for secondary pollutants formed from a chemical reaction. The most common is ozone.

Which is a secondary air pollutant quizlet?

Secondary air pollutant is. carbon monoxide, nitrogen oxides, sulfur dioxide, volatile organic compounds, particulate matter. Examples of primary pollutant are. ground-level ozone.

What type of pollution is carbon dioxide?

Carbon dioxide contributes to air pollution in its role in the greenhouse effect. Carbon dioxide traps radiation at ground level, creating ground-level ozone. This atmospheric layer prevents the earth from cooling at night. One result is a warming of ocean waters.

Is carbon monoxide a air pollution?

Carbon monoxide (CO)—a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood.

Is carbon dioxide a air pollutant?

Summary: Rising carbon dioxide levels from burning fossil fuels have been linked to sea level changes, snowmelt, disease, heat stress, severe weather, and ocean acidification. Yet because it does not affect respiration directly, carbon dioxide is not considered a classic air pollutant.

What are the 5 causes of climate?

5 Causes of Global Warming

  • Greenhouse Gases Are the Main Reasons for Global Warming.
  • Cause #1: Variations in the Sun’s Intensity.
  • Cause #2: Industrial Activity.
  • Cause #3: Agricultural Activity.
  • Cause #4: Deforestation.
  • Cause #5: Earth’s Own Feedback Loop.
