AP Environmental Science: Unit 7 Review - Air Pollution

Solutions

________- replacing ozone- depleting chemicals with substitutes that do not such as Hydrofluorocarbons (HFCs)

Asbestos

________- long, thin, fibrous silicate material with insulating properties, can cause respiratory diseases.

CO

________- colorless gas that occurs with incomplete combustion, very deadly.

CO2

________- colorless gas that occurs with combustion of fossil fuels and clearing land, increases greenhouse gas concentrations.

AP Environmental Science

________: Unit 7 Review- Air Pollution.

VOCs

________- from furniture, paneling, carpets.

Secondary pollutants

________- form once in atmosphere.

Human health

________- respiratory problems and eye irritation.

Wet dry scrubbers

________- devices that remove harmful particulates and /or gases from industrial exhaust streams.

Thermal inversion

________- warmer layer on top of cooler surface.

Carbon monoxide

________ (CO)- formed with incomplete combustion, classified as an asphyxiant.

Noise pollution

________- include transportation, construction, and domestic and industrial activity.

Formation

________- nitrogen oxides and volatile organic hydrocarbons (VOCs) react with heat and sunlight to produce a variety of pollutants.

Ozone hole

________- located in Antartica.

Stratospheric ozone layer

________- important to the evolution of life on Earth, protects us from harmful ultraviolet light from the sun.

Primary pollutants

________- emitted directly into atmosphere.

Reduction

________- through the reduction of nitrogen oxide and VOCs.

Catalytic convertor

________- device for internal combustion engines that converts pollutants in exhaust into less harmful molecules.

Nitric acid HNO3

________- acid that forms in the atmosphere from oxides of nitrogen.

Sulfur oxides SOx

________- corrosive gas that forms when sulfur combines with oxygen during coal combustion, respiratory irritant that can harm plan tissue and also form secondary pollutants like sulfuric acid in the atmosphere.

Sulfuric acid H2SO4

________- formed from sulfur oxides reacting with water vapor in the air.

Solutions

________- regulatory practices, conservation practices, and alternative fuels.
