Air Pollution Flashcards
Is the contamination of air due to the presence of substances that are harmful to the health of living organisms and the non-living things.
Air pollution
Are any harmful substance like certain chemicals or waste products that renders the air soil water or other natural resources.
Pollutants
Also known as smog (combination of smoke and fog), it can harm plants, animals, and human beings.
Ground-level ozone
Is a colorless, odorless, and tasteless gas and is toxic to animals and human beings. Also known as the “silent killer”
Carbon monoxide
Is made of tiny carbon particles created by incomplete combustion of fossil fuels.
Soot
Is a gaseous air pollutant composed of nitrogen and oxygen.
Nitrogen Oxide
Is a gaseous air pollutant composed of sulfur and oxygen. It is a colorless gas with a pungent odor.
Sulfur Dioxide
It can adversely affect the nervous system, kidney function, immune system, reproductive and developmental systems, and the cardiovascular system.

Two Causes of Air Pollution
✓ Human Activities
✓ Natural Environment
CATEGORIES OF AIR POLLUTANTS
Are air pollutants DIRECTLY EMITTED from a source.
Primary Pollutant
Are air pollutants that are not directly emitted as such but forms when two primary pollutants react in the atmosphere.
Secondary Pollutants
Is a mixture of different gases in the atmosphere.
Air
Composition of Air
21% Oxygen, 78% Nitrogen
The horizontal motion of air due to the pressure difference between two places.
Wind
Is a suspension of fine solid particles or liquid droplets in air or another gas.
Aerosol
Fog, mist, and dust are an example of _______ aerosol.
Natural Aerosol
Smoke, Sprayed Pesticides, and Particulate air pollutants are an example of _____________ Aerosol.
Anthropogenic Aerosol
The amount of water the air can hold before it rains.
Relative humidity
Air pollution is the ______ largest threat to human health.

Natural Sources
Are also called anthropogenic sources which include naturally occurring pollutants released from human activities.
Man-Made Sources
Are also called household sources of pollution, which include fuel for cooking, heating and lighting of incense, use of pesticides and chemicals for cleaning, etc.
