AKA
These devices are used on coal power plants to reduce particulate pollution.
What are electrostatic precipitators?
These pollutants come from compounds which come directly out of the smoke-stack, exhaust pipe, or emission source.
What are primary pollutants?
This layer of gas has the ability to absorb ultraviolet radiation and protect life on Earth.
What is ozone?
This exceptionally strong warming of eastern pacific waters can result in global temperature and precipitation change.
What is el nino?
This indoor air pollutant binds with hemoglobin in the blood and prevents the binding of oxygen, making it toxic.
What is CO?
The introduction of chemicals or particulate matter into the atmosphere at concentrations high enough to harm plants, animals, buildings, or to alter ecosystems.
What is air pollution?
Most of the earth's air pollution occurs in this layer of the atmosphere.
What is the troposhere?
The precursors, or "ingredients," the cause this are VOCs, NOx gases and water vapor in the presence of sunlight.
What is photochemical smog?
This phenomena occurs in valleys and traps pollutants under a layer of warm air.
What is thermal inversion?
These types of pollutants undergo transformation in the presence of sunlight, water, oxygen, or other compounds.
What are secondary pollutants?
The thinning of this has increased the amount of UV-B radiation that reaches the surface of Earth.
What is the ozone layer?
The gas which is the largest contributor to earth's atmosphere.
What is nitrogen?
Chlorofluorocarbons are knows more commonly as this.
What are CFCs?
Volcanoes, forest fires and road construction are all forms of this kind of pollution.
What is particulate pollution?
Examples of this level of pollution are tropospheric ozone, sulfuric acid and nitric acid
What is secondary pollution?
Thermal inversion is caused when a layer of this type of air traps cold air (and the pollution within the cold air) beneath it.
What is warm air?
This gas is produced by microbes decomposing matter in landfills.
What is methane?
Acid rain is the liquid form of this.
What is acid deposition?
The most common natural source of VOC's.
What are trees?
This type of gas is an indoor pollutant which enters the basements of houses through cracks. It is produced by the natural decay of Uranium.
What is radon?
The ozone layer exists roughly 45-60 kilometers above the Earth in this layer of the atmosphere.
What is the stratosphere?
These are the major source of chlorine in the stratosphere and are used in refrigeration and air conditioning, as propellants in aerosol cans and as “blowing agents” to inject air into foam products like Styrofoam.
What are CFCs?
