Air Pollution

is the contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.

• Air pollution

• Air pollutants

• Dust

• Air Chemicals

are substances in air that could, at high enough concentrations, harm human beings, animals, vegetation or material.

• Air Pollution

• Air Pollutants

• Air Chemicals

• Dust

This air pollutant consists of particles (tiny pieces) of solids or liquids in the air. These particles may include dust, dirt, and soot.

• Particulate Matter

• Ozone

• Sulfur Dioxide

• Nitrogen Oxide

This refers to particulate matter that is 10 micrometers or less in diameter.

• PM 2.5

• PM 1

• PM 2

• PM 10

This includes dust from construction sites, landfills, agriculture, wildfires, brush and waste burning, industrial sources, wind-blown dust from open lands, pollen, and fragments of bacteria.

• PM 2.5

• PM 1

• PM 2

• PM 10

This refers to particulate matter that is 2.5 micrometers or less in diameter. These particles are considered fine particles and are among the smallest and most dangerous types of air pollution.

• PM 2.5

• PM 1

• PM 2

• PM 10

a gas that is produced both naturally and as a result of human activity. In the upper atmosphere, it protects the planet from harmful UV radiation. However, on earth, which forms when pollutants from cars and industry react with sunlight and heat, is a pollutant that can cause respiratory problems and harm the environment.

• Particulate matter

• Sulfur Dioxide

• Ozone

• Nitrogen Oxides

How is ground-level ozone formed?

• Through natural processes such as sunlight and wind

• By the release of ozone from the stratosphere to the lower atmosphere

• Through the reaction of pollutants from human activities with sunlight

• By the release of ozone from the troposphere to the lower atmosphere

What is/are the effects of ground-level ozone?

• Improved respiratory function

• Enhanced plant growth

• Improved visibility

• Damaged respiratory and cardiovascular systems

a gas that is a major cause of acid rain and is created when fossil fuels are burned. It can harm the environment and lead to respiratory issues, especially for those who have asthma.

• Ozone

• Nitrogen Oxides

• Sulfur Dioxide

• Carbon Monoxide
