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 are the 7 major air pollutants?
When talking about air quality, we commonly mean the levels of different pollutants in our air. Major air pollutants include carbon monoxide (CO), ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), sulphur dioxide (SO2) and volatile organic compounds (VOC).
What causes pollution?
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. The solid and liquid particles suspended in our air are called aerosols.
What is the largest 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.
What are the 6 types of air pollution?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
What is the most harmful air pollutant?
Nitrogen oxides are a group of air polluting chemical compounds, including nitrogen dioxide (NO2) and nitrogen monoxide. NO2 is the most harmful of these compounds and is generated from the combustion of fuel engines and industry.
What is an environmental pollutant?
Environmental pollutants are compounds introduced in the natural environment causing adverse changes, for example, adversely affecting health or causing other types of damage. Among these, the pesticides, herbicides, and fungicides are of considerable interest since they have a large-scale use in agriculture.
How do humans cause pollution?
Humans pollute the air, land, and sea by burning fossil fuels, overusing chemicals and pesticides, and creating sewage run-off. The health consequences of that pollution are clear: Air pollution causes some 8.8 million deaths annually worldwide.
What causes poor air quality?
There are many factors that can lead to poor air quality, but the two most common are related to elevated concentrations of ground-level ozone or particulate matter. ... Sunshine, rain, higher temperatures, wind speed, air turbulence, and mixing depths all affect pollutant concentrations.
What is pollution Short answer?
Pollution is the introduction of harmful materials into the environment. ... Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
