Classification of air pollutants on the basis of chemical composition
What are the classifications of air pollutants?
Classification of Pollutants

What are the 4 types of air pollutants?
The common air pollutants are:
- Particulate matter (PM10 and PM2. …
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Carbon monoxide (CO)
- Sulphur dioxide (SO2)
What are 4 major chemical pollutants?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
What are the three classification of pollutants?
From an ecological perspective, pollutants can be classified as degradable, slowly degradable and non-degradable. The Degradable or called as non-persistent pollutants can be rapidly broken down by natural process.
What are the 7 criteria air pollutants?
The criteria air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm your health and the environment, and cause property damage.
What are the 2 main types of air pollution?
There are two main types of air pollutants: primary and secondary. Most air pollutants come from burning fossil fuels. Some come from burning forests. Some are due to the evaporation of chemicals.
What are the five ways to classify pollutants?
The five major types of pollution include: air pollution, water pollution, soil pollution, light pollution, and noise pollution.
What are the classification of pollutants based on origin?
According to origin, particulate matter can be divided into two types, viz., natural and man-made. The natural form of particulate matter is the result of volcanic dust and gases, mineral dust and sea-salt crystals. Another class of natural particulate matter is smoke from forest and grass fires.
What is air pollution classify air pollutants and give it’s sources?
According to origin: The air pollutants are classified into: Primary pollutants: The pollutants that are emitted directly from identifiable sources produced by natural events. ( eg: dust storms and volcanic eruptions) and human activities (eg: emissions from vehicles, industries etc.)
What are the 5 major types of pollution?
What are the different types of pollution?
- Air pollution.
- Water pollution.
- Soil pollution.
- Radioactive pollution.
- Noise pollution.
What are 5 pollutants?
Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, and water pollution.
What is the most harmful air pollutant?
Nitrogen Dioxide
NO2 is the most harmful of these compounds and is generated from the combustion of fuel engines and industry. It can damage the human heart and lungs and it reduces atmospheric visibility at high concentrations. Finally, it is a critical precursor to the formation of ground-level ozone.
What is the most common type of air pollution?
Most Common Air Pollutants
- Carbon Monoxide.
- Nitrogen Dioxide (EPA)
- Ozone (EPA)
- Particulate Matter.
- Lead (EPA)
- Sulfur Dioxide.
- Six Common Pollutants (EPA)
What are pollutants and its types?
Different types of pollutants include: Nitrogen oxides (NOx) Sulfur oxides (SOx) Particulate matter (PM) Ground level ozone (O3)
What are primary and secondary 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 the major air pollutants and their source?
The gaseous criteria air pollutants of primary concern in urban settings include sulfur dioxide, nitrogen dioxide, and carbon monoxide; these are emitted directly into the air from fossil fuels such as fuel oil, gasoline, and natural gas that are burned in power plants, automobiles, and other combustion sources.
What are pollutants give example?
Any substance that makes the environment dirty or contaminated is a pollutant. Soot is an example of an air pollutant, and chemical pollutants can make their way into the water supply. Trash that doesn’t quickly biodegrade is one kind of pollutant—think of plastic bags floating around in the ocean.
What are the major pollutants in India?
Under N.A.M.P., four air pollutants viz ., Sulphur Dioxide (SO2), Oxides of Nitrogen as NO2, Respirable Suspended Particulate Matter (RSPM / PM10) and Fine Particulate Matter (PM2. 5) have been identified for regular monitoring at all the locations.

What are the 6 levels of air quality?
How does the AQI work?
| Daily AQI Color | Levels of Concern | Values of Index |
|---|---|---|
| Green | Good | 0 to 50 |
| Yellow | Moderate | 51 to 100 |
| Orange | Unhealthy for Sensitive Groups | 101 to 150 |
| Red | Unhealthy | 151 to 200 |
What is the meaning of air pollutants?
Air pollutants are substances in air that could, at high enough concentrations, harm human beings, animals, vegetation or material. Air pollutants may thus include forms of matter of almost any natural or artificial composition capable of being airborne.
What are the 3 main causes of air pollution?
Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.
What is the main cause of pollution?
Burning Fossil Fuels
The biggest contributors of air pollution are from industry sources and power plants to generate power, as well as fossil fuel motor vehicles. The continuous burning of fossil fuels releases air pollutants, emissions and chemicals into the air and atmosphere.
