Intro to Air Pollution
The introduction of chemicals, particulate matter, or microorganisms into the atmosphere at concentrations high enough to harm plants, animals, and materials such as buildings, or to alter ecosystems.
What is air pollution?
Also known as Los Angeles-type smog or brown smog.
What is photochemical smog?
Usually referred to as “the silent killer”.
What is carbon monoxide?
A device that uses chemicals to convert pollutants such as nitrogen oxide and carbon monoxide to nitrogen gas and carbon dioxide.
What is a catalytic converter?
Acidified precipitation derived from air pollutants.
What is acid rain?
Most commonly known as a class of pollutants released from the combustion of fuels such as coal and oil.
What is particulate matter?
A by-product of respiration, decomposition, and combustion.
What is carbon dioxide?
Compounds that adversely affect the quality of air in buildings and structure.
What are indoor air pollutants?
A control device that uses lime or water to filter industrial exhaust streams.
What is a scrubber?
Another term for precipitation high in sulfuric and nitric acid.
What is acid deposition?
They play an important role in the formation of photochemical oxidants such as ozone.
What are volatile organic compounds?
They trap air pollutants close to Earth’s surface.
What are thermal inversions?
A cancerous fibrous silicate mineral that resides within building insulation.
What is asbestos?
A control device that uses an electrical charge to remove particulate matter from exhaust streams.
What is an electrostatic precipitator?
When in the water, may interfere with animal communicatio.
What is noise pollution?
CO, CO2, SO2, NO, NO2, most hydrocarbons, most suspended particle.
What are primary pollutants?
Natural processes responsible for particulate emissions and carbon dioxide.
What are volcanoes, forest fires, respiration, and decompositio.
These use wood, animal manure, or coal indoors for heat and cooking.
What are developing countries?
Has controlled and reduced air pollution, along with prevention, conservation, and rule switching.
What are regulatory practices?
A logarithmic scale that measure both the loudness of sound and the frequenc.
What is a decibel A scale?
The law that required lead be phased out as a gasoline additive in the United States between 1975-1996.
What is the Clean Air Act?
C6H12O6>3CO2+3CH4+less energy
What is anaerobic decomposition without oxygen?
A type of poisoning that can potentially come from the exposure of paint in old building.
What is lead?
A control device on the nozzle of a gasoline dispenser that reduces the amount of VOC fumes released into the atmosphere.
What is a vapor recovery nozzle.
The relative strength of acids and bases in a substance.
What is pH?
