Unit 7 review- env. science atmospheric pollution

Air Quality Index (AQI)

• Air Quality Index (AQI) is a measure of the amount of oxygen in the air
• Air Quality Index (AQI) is a measurement used to communicate how polluted the air currently is and what associated health effects might be of concern.
• Air Quality Index (AQI) is used to determine the best time for outdoor activities
• Air Quality Index (AQI) measures the temperature of the air

Carbon monoxide (CO

• Carbon monoxide (CO) is a type of renewable energy source.
• Carbon monoxide (CO) is a toxic gas produced by incomplete combustion of carbon-containing fuels.
• Carbon monoxide (CO) is a solid substance found in nature.
• Carbon monoxide (CO) is a harmless gas used in medical treatments.

Inversion

• an atmospheric condition where a layer of cooler air is trapped near the ground by a layer of warmer air above

• Inversion is a mathematical operation
• Inversion refers to a type of dance move
• Inversion is a cooking technique

Tropospheric of Ground Level Ozone

• Ground-level ozone is formed when pollutants emitted by trees react in the presence of sunlight.
• Ground-level ozone is formed when pollutants emitted by bicycles react in the presence of sunlight.
• Ground-level ozone is formed when pollutants emitted by vehicles, power plants, and other sources react in the presence of sunlight.
• Ground-level ozone is formed when pollutants emitted by factories react in the presence of moonlight.

Particle pollution

• Particle pollution is a mixture of solid particles and liquid droplets found in the air.
• Particle pollution is only found indoors.
• Particle pollution is a type of noise pollution.
• Particle pollution is caused by excessive sunlight exposure.

Sulfur dioxide

• Sulfur dioxide is a colorless gas with a pungent odor.
• Sulfur dioxide is a solid at room temperature.
• Sulfur dioxide has a sweet smell.
• Sulfur dioxide is used in baking cakes.

A carcinogen produced from radioactive decay of Uranium-28. Found naturally in some soils.

• Radon

• Lead

• Mercury

• Ozone

A strong VOC and greenhouse gas, made in excess from livestock.

• Carbon Dioxide

• Lead

• Mercury

• Methane

A protective gas in the stratosphere, but a pollutant in the troposphere.

• Ozone

• Nitrogen

• Radon

• Methane

Produced from interactions between primary air pollutants, or between primary air pollutants and other atmospheric gases.

• Primary Air Pollutants

• Secondary Air Pollutants

• Point Source Pollutants

• Non-Point Source Pollutants
