What are the classifications of air pollutants?
Classification of Pollutants
| Particulate Pollutants | Gaseous Pollutants | |
|---|---|---|
| Lead Fly Ash Metallic Oxides Nanoparticles | Carbon monoxide (CO) Carbon dioxide (CO2) Chlorofluorocarbons (CFCs) Ozone (O3) Nitrogen oxide (NOx) Sulphur dioxide (SO2) | Volatile organic compounds (VOCs) Benzene Ethylene Biological pollutants Asbestos Radon |
What is air pollutants and its types?
The EPA identified six major types of air pollutants deemed especially harmful to human health. These are carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, particulate matter and lead. Since the Clean Air Act of 1970 and the identification of these pollutants, air pollution has decreased markedly.
What are the 5 types of pollutants?
5 Major Outdoor Air Pollutants
- Ozone (O3)
- Nitrogen Oxides (NOx)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
- Particulate Matter (PM10 and PM2.5)
What are the 4 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 the 2 types of air pollutants?
Air Pollutants. There are two main types of air pollutants: primary and secondary.
What are the types of air pollution PDF?
Types of air pollution
- particulate matter.
- nitrogen dioxide.
- ozone.
- sulphur dioxide.
How many types of pollutants are there?
The three major types of pollution are air pollution, water pollution, and land pollution.
What are two types of air pollutants?
What are the six air pollutants?
They are particulate matter (often referred to as particle pollution), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm human health, harm the environment, and cause property damage.
What is an air pollutant?
Common Air Pollutants They are particulate matter (often referred to as particle pollution), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm human health, harm the environment, and cause property damage.
How are the pollutants classified give one example of each type?
i) Waste: e.g., glass, plastic, phenolics, aluminium cans, etc. ii) Poisons: e.g., radio-active substances, pesticides, smog gases, heavy metals like mercury, lead and their salts.
How the Air pollutants are classified as primary and secondary pollutants explain with example?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
What is pollution and types pdf?
KINDS OF POLLUTION The pollution is of four major types namely air pollution, water pollution, land pollution and noise pollution.
What is the main air pollutant?
The main gaseous pollutants are ozone, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The main particulate matter (PM) pollutants are defined according to their aerodynamic diameter (those ≤10 μm referred to as PM10 and those ≤2.5 μm referred to as PM2.5).
What are pollutants?
Pollutants are the substances which cause pollution; air pollution is caused by air pollutants. The pollutants that directly cause air pollution are known as primary pollutants. The pollutants formed by the intermingling and reaction of primary pollutants are known as secondary pollutants.
What are the 6 types of air pollutants?
They are particulate matter (often referred to as particle pollution), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm human health, harm the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats.
What are the primary and secondary pollutants?
The pollutants that directly cause air pollution are known as primary pollutants. The pollutants formed by the intermingling and reaction of primary pollutants are known as secondary pollutants. The particles that pollute the air by being suspended can be defined as particulate pollutants.
What are the substances that cause air pollution?
The substances that cause air pollution are called air pollutants, and they may be in the form of a gas, liquid, or solid. Air pollutants are transboundary in nature as they travel and affect areas far away from their point of origin. Air pollution causes adverse effects on humans and other living organisms.
