air pollution Flashcards
is the
contamination ofthe
atmosphere by
harmful substances,
which can arise from
both natural sources
and human
activities.
Airpollution
It refers to any physical,
chemical or biological
change in the air.
Airpollution
Substances not
naturally found in the
air or at greater
concentrations or in
different locations
from usual are
referred to as
_____________.
pollutants
The pollutants that
directly cause air
pollution
primary pollutants
are emitted
from burning
pollutants of coal
and oil.
Sulfur oxides (SOx)
are emitted from high
temperature combustion.
Can be seen as the brown
haze dome above or plume
downwind of cities.
Nitrogen oxides (NOx)
a greenhouse gas emitted
from energy production,
including burning coal, oil,
or natural gas.
Carbon dioxide (CO2 ),
It is a colorless, odorless and non irritating
byproduct of fuels like coal,
wood, or natural gas burning
incompletely.
carbon monoxide
emitted
from agricultural processes.
It is a colorless highly
irritating gas with a sharp
suffocating odor.
Ammonia(NH3)
is quantified by dust
and smoke.
or particulate matter,
is the percentage of suspended
particles that will penetrate the nasal cavity and
have a diameter of 10 micrometers or less.
PM10
_______ can
penetrate the lungs and bronchi.
PM2.5
War munitions, nuclear
explosions, and natural
processes like radon
radioactive decay all
produce ____________
radioactive
pollution.
pollutants formed by
the intermingling and
reaction of primary
pollutants are known as
__________________.
secondarypollutants
formed from NOx and
VOCs. It is a colorless and
highly irritating gas that
forms just above the earth’
s
surface.
Groundlevel ozone (O3
similarly formed from
NOx and VOCs, present in
photochemical smog.
Peroxyacetyl nitrate
(PAN) similarly
sources of air pollution
anthropogenic and natural,
____________ began in
the mid-1700s, when
Europe and North
America entered the
period of time known
as the I______________
human-caused air pollution, industrial revolution
Most air pollution is
created by people
burning fossil
fuels, which include
____,_____,and ______
coal, natural gas
and oil.
anthropogenic ways of air pollution
-burning fossil fuel
-fumes
-waste deposition
-military
-agricultural operations
-mining process
natural ways of air pollution
- methane
-dust from natural sources
-volcanic activity
-smoke and carbon monoxide from wildfires
emitted by
the digestion of food by
animals,
Methane,
effects on the environment of air pollution
-acid rain
-decrease sunlight
-temperature inversion
-hole in the ozone layer
-
forms when sulfur
dioxide and nitrogen dioxide
mix with water droplets in the
atmosphere to make sulfuric
acid and nitric acid.
acid rain
Result of Acid Rain
-harms vegetation by
damaging leaves
-increases soil and water
acidity
-decay the buildings and
monuments
effects of air pollution in humans
-stroke
-heart disease
- lung disease
-pneumonia
-mental health
-diabetes
-cancer
-highblood pressure
reduction of air pollution
-Reduce your driving.
-Keep your vehicle well maintained.
-Turn off engine when not in use.
-Avoid burning trash.
-Limit backyard fires.
-Plant and maintain trees.
-Opt for electric or manual lawn
equipment.
-Reduce energy consumption.
-Advocate for clean air;
and many more :)
issued new air quality guidelines
in 2021 to set stricter limits on the
amount of air pollution people can
safely be exposed to each year.
World Health Organization (WHO)
The Act provides for the creation of a
national program of air pollution
management focusing primarily on
pollution prevention; for the promotion
of mass media communication in order
to create social awareness and active
participation in air quality planning and
monitoring.
CLEAN AIR ACT OF 1999
