What type of air pollution is most harmful?
Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats.
EPA calls these six pollutants “criteria” air pollutants because it regulates them by developing limits that are based on human health and/or environmental criteria.

Is dust a primary or secondary pollutant?
Air Pollution. Primary – Dust, smoke particles, nitrogen, carbon etc. Secondary – Formed when primary pollutants react or combine with one another, or the basic elements.
What is the primary air pollutant?
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 is the #1 cause of pollution?
1. The Burning of Fossil Fuels. Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum for energy in power plants, and other factory combustibles is one the major cause of air pollution.
What two pollutants pose the greatest threat to human?
Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.
What are examples of primary and secondary pollutants?
Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.
What are the 5 primary pollutants?
Primary pollutantNitrogen oxides (NOx)Carbon monoxide (CO)Volatile organic compounds (VOCs)Sulfur oxides (SOx)Particulate matter (PM)Mercury.and more.
What are the 5 primary air pollutants and their sources?
Name five primary air pollutants, and give sources for each. The five primary air pollutants include carbon monoxide, nitrogen oxides, particulate matter, sulfur oxides, and volatile organic compounds. The sources for all five of these pollutants include electricity production, industry, and transportation.
Which air pollutant traps the most heat?
That’s because carbon dioxide is the most common of the greenhouse gases, which trap heat in the atmosphere and contribute to climate change. Humans have pumped enough carbon dioxide into the atmosphere over the past 150 years to raise its levels higher than they have been for hundreds of thousands of years.
Which is more harmful primary or secondary pollutants?
2) Which are more harmful primary or secondary pollutants? Ans- They emit carbon monoxide which is one of the biggest contributors (by weight) to air pollution. Though these statistics are horrifying, secondary pollutants can be more harmful and severe to human health than primary pollutants.
