colorless, odorless gas produced by burning carbon & organic compounds & by respiration
carbon dioxide
gas once commonly used in various products (aerosols) but thats believed to cause damage to the ozone layer in the Earth’s atmosphere
Chlorofluorocarbons
primary federal law in the US governing air pollution
Clean Air Act
six common air pollutants known to be harmful to health & the environment: particulates, sulfur dioxide, carbon monoxide, nitrogen oxides, ozone, lead.
Criteria Air Pollutants
US federal law passed by Congress in response to concerns regarding environmental & safety hazards posed by storage & handling of toxic chemicals
emergency planning & community right to know act
Legal requirements governing air pollutants released into the atmosphere. Sets quantitive limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes.
Emissions standards
A gas that absorbs radiation of specific wavelengths within the infrared spectrum of radiation emitted by the Earth’s surface and clouds. The effect is a local trapping of part of the absorbed energy and a tendency to warm the Earth’s surface. Water vapor, carbon dioxide, nitrous oxide, methane and ozone are primary examples in the Earth’s atmosphere.
Greenhouse gas
layer in earth’s stratosphere at an altitude of about 6.2 mi containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun
ozone layer
air quality was noticeably deteriorating in the US during the 1950s & 1960s due to which of the following?
a) coal burning
b) railroad locomotives
c) industrial furnaces
d) automobiles
automobiles
Bush administration issued rules on what type of pollution by coal-burning power plants that were later found by the courts to be inadequate & ineffective?
a) mercury
b) lead
c) carbon monoxide
d) sulfur dioxide
mercury
what major component of the atmosphere may have ominous implications for the future of the earth’s environment due to its increasing proportion?
a) carbon dioxide
b) nitrogen
c) oxygen
d) argon
carbon dioxide

the Clear Skies Initiative clearly set more stringent emissions standards than those required by the Clean Air Act
false
TRUE OR FALSE:
the ban on leaded gasoline has almost eliminated lead as an air pollutant
