describes the 6 air pollutants that have been regulated and are used as indicators of general air quality

• Criteria Air Pollutants
• Clean Air Pollutants
• Primary Pollutants
• Secondary Pollutants

pollutants that are put directly into the air by human or natural activity.

• Primary Pollutants
• Secondary Pollutants
• Source Pollutants
• Indirect Pollutants

pollutants that form from chemical reactions that occur when primary pollutants come in contact with other primary pollutants or with naturally occurring substances, such as water vapor.

• Secondary Pollutants
• Primary Pollutants
• Source Pollutants
• Indirect Pollutants

Formed when nitrogen oxides and volatile organic hydrocarbons react with heat and sunlight to produce a variety of pollutants.

• Photochemical Smog
• Volatile Organic Compounds (VOCs)
• Hydrocarbons
• Acid Rain

Molecules that evaporate or sublimate at room temperature.

• Volatile Organic Compounds (VOCs)
• Photochemical Smog
• Hydrocarbons
• Sulfur Dioxide (SO2)

NGSS.HS-PS1-2

When the normal temperature gradient in the atmosphere is altered as the air temperature at the Earth's surface is cooler than the air at higher altitudes.

• Thermal Inversion
• Rain Shadow Effect
• Hadley Cell
• El Nino

Substance (such as a toxic gas) or event (such as drowning) that creates a lack of oxygen in the body.

• Asphyxiant
• Neurotoxin
• Endocrin Disruptor
• Persistant Organic Pollutants (POPs)

A long, thin, fibrous silicate mineral with insulating properties, which can cause cancer when inhaled.

• Asbestos
• Black Mold
• Radon-222
• Carbon Monoxide (CO)

A class of mold that releases spores into the air and is especially harmful to the respiratory system

• Black Mold
• Asbestos
• Radon-222
• Carbon Monoxide (CO)
