What are the 3 types of pollutants?
The three major types of pollution are air pollution, water pollution, and land pollution.
What are the two types of pollutants?
The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.
What are the five pollutants?
5 Major Outdoor Air Pollutants
- Ozone (O3)
- Nitrogen Oxides (NOx)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
- Particulate Matter (PM10 and PM2.5)

- Particulate matter (PM10 and PM2.
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Carbon monoxide (CO)
- Sulphur dioxide (SO2)
Which two pollutants are the greatest threat to human health?
Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.
What type of air pollution is most harmful?
UFPs

- Ozone (EPA)
- Particulate Matter.
- Lead (EPA)
- Sulfur Dioxide.
- Six Common Pollutants (EPA)
Which of the following is most harmful pollutant?
Sulphur dioxide
What are four sources of particulate matter?
Particulate Matter (PM) Sources. Components of particulate matter (PM) include finely divided solids or liquids such as dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors that can be suspended in the air for extended periods of time.
What are good air quality numbers?
Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
Why pollution is dangerous?
Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases. Toxic chemicals that accumulate in top predators can make some species unsafe to eat.
What is air pollution in very short answer?
Air pollution is a type of environmental pollution that affects the air and is usually caused by smoke or other harmful gases, mainly oxides of carbon, sulphur and nitrogen. In other words, air pollution is the contamination of air due to the presence or introduction of a substance which has a poisonous effect.
