Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans. Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources.
When did the air pollution started?
Evidence from Greece shows that the problems of polluted air outdoors were being documented at least 2400 years ago.
How did pollution become a problem?
Through the 19th century, water and air pollution and the accumulation of solid wastes were largely problems of congested urban areas. But, with the rapid spread of industrialization and the growth of the human population to unprecedented levels, pollution became a universal problem.
How is air pollution naturally caused?
There are natural processes that create air pollution— such as sulfur and chlorine gases from volcanic activity, smoke and ash from wildfires, dust storms, and biological decay — but most pollution enters the air from human-made (anthropogenic) sources.
How was air pollution created? – Related Questions
Who is causing pollution?
The Short Answer:
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires.
What is the biggest source of air 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.
What is natural air pollutant?
Naturally occurring pollutants include ash, soot, sulfur dioxide, ground-level ozone (also known as smog), salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires.
What is natural pollution?
A natural pollutant is a pollutant created by substances of natural origin such as volcanic dust, sea salt particles, photochemically formed ozone, and products of forest fibres, among others.
What are the 7 causes of air pollution?

- The Burning of Fossil Fuels.
- Industrial Emission.
- Indoor Air Pollution.
- Wildfires.
- Microbial Decaying Process.
- Transportation.
- Open Burning of Garbage Waste.
- Construction and Demolition.
What are the natural and man made pollutants that cause air pollution?
Natural: It is the pollution caused by nature. It includes forest fires, dust storms, pollen etc. Human made: It is the pollution caused by human activities. It includes burning of fossil fuels in industries, vehicles and thermoelectric plants, gaseous emission from industries, mining, processing and stone crushing.
How do we control air pollution?
Reduce the number of trips you take in your car. Reduce or eliminate fireplace and wood stove use. Avoid burning leaves, trash, and other materials. Avoid using gas-powered lawn and garden equipment.
How can we prevent air pollution?

Can air pollution be stopped?
Air pollution can be prevented by advocating the use of public transport and carpooling. It can also be controlled by avoiding wastage of electricity and practicing reuse and recycling of compatible products.
Can pollution be controlled?
If everyone realizes the hazards it may create and cooperates to get rid of it, pollution may be controlled.
What is the first step to reduce pollution?
Using fewer fossil fuels, such as gasoline for a car, reduces the emission of harmful pollutants into the air. Reusing, reducing, and recycling reduces the number of landfills needed. What is the first step to take to help reduce pollution? Donate money to an organization that works to fight water and air pollution.
What is the conclusion of air pollution?
CONCLUSION. While the effects of air pollution on materials, vegetation, and animals can be measured, health effects on humans can only be estimated from epidemiological evidence. Most of the evidence comes from occupational exposure to much higher concentrations of pollutants than the general public is exposed to.
What is air quality control?
Air quality management refers to all the activities a regulatory authority undertakes to help protect human health and the environment from the harmful effects of air pollution. The process of managing air quality can be illustrated as a cycle of inter-related elements.
What are the effects air pollution?
Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.
