Cards

Term
Primary Pollutant
Definition
harmful chemicals released directly into the atmosphere...ex: SO2, NOx, CO2, CO, hydrocarbons, SPM
Term
Secondary pollutant
Definition
harmful chemicals that form from the reaction of other substances released into the atmosphere..ex: tropospheric ozone, sulfur dioxide
Term
SPM
Definition
suspended particulate matter..ex: dust, asbestos, pollen
Term
Main two gases in atmosphere
Definition
Nitrogen (78%), Oxygen (21%)
Term
Layers in the atmosphere-in order-lowest to highest
Definition
troposphere, stratosphere, mesosphere, thermosphere, exosphere
Term
industrial smog
Definition
gray-smog, more pollutants from industry
Term
photochemical smog
Definition
yellow/brown smog, smog formed with the reaction of a pollutant with UV rays, example...ground level ozone
Term
SO2
Definition
sulfur dioxide
Term
CO
Definition
carbon monoxide
Term
CO2
Definition
carbon dioxide
Term
NOx
Definition
nitrogen oxide (NO2-Nitrogen Dioxide)
Term
stratospheric ozone
Definition
good ozone-protects from UV rays
Term
tropospheric ozone
Definition
bad ozone- reactive- component of photochemical smog
Term
why is rain naturally acid?
Definition
the reaction of carbon dioxide and water forms carbonic acid, which makes the rain slightly acidic.
Term
List 3 problems of acid rain?
Definition
check your notes...there are many
Term
electrostatic precipitators, scrubbers, fabric filters
Definition
technologies helping to remove particulate matter and harmful compounds from coal burning plants
Term
health problems from acid deposition
Definition
respiratory issues, emphysema, bronchitis
Term
layer of atmosphere where most UV rays are absorbed
Definition
stratosphere
Term
lapse rate
Definition
shows temperature rate change in the troposphere
Term
CFCs
Definition
chloroflurocarbons, once used in aerosol cans, coolants in refrigerators air conditioners..one of the chemicals causing ozone depletion
Term
Montreal Protocol
Definition
multinational agreement to ban the use of CFCs, cutting back the impact of ozone depletion
Term
Factors effecting regional acid deposition
Definition
industry location, local geology and wind/weather patterns.
Term
Examples of indoor air pollutant
Definition
carbon monoxide, cigarette smoke, radon, formaldehyde
Term
Examples of Hydrocarbons
Definition
methane, benzene, gasoline, waxes (paraffin)
Term
temperature inversion
Definition
layer of cold air is trapped under warm air above and can cause a build up in air pollution (smog)
Term
United States Clean Air Act
Definition
(Control Act in 1955, then clean air-in 1970,has been amended several times)- regulates -sets limits on on air pollutants.
Term
Order of UV rays -most dangerous to least dangerous
Definition
UVc, UVb, UVa
Term
Three primary pollutants that cause acid deposition (include source)
Definition
SO2: coal burning; CO2: combustion/burning fossil fuels; NOX: combustion-esp car exhaust
Term
Name a primary pollutant that contributes to bad ozone formation. How?
Definition
NOx...car exhaust, NOx reacts with UV rays...end result...tropospheric O3
