ENVIRONMENTAL POLLUTION Flashcards
Kinds of pollution (5)
AIR POLLUTION
WATER POLLUTION
LIGHT POLLUTION
NOISE POLLUTION
THERMAL OR HEAT
POLLUTION
is the introduction of
contaminants into the
natural environment that
cause adverse change.
Pollution
Air that are harmful to human health
Air Pollution
According to World Health
Organization (WHO) Air
pollution kills an estimated
seven (7) million people
it is major pollutantin urban
air
CARBON MONOXIDE
Formed mainly from N2
and O2 during hightemperature combustion offuel in cars.
NITROGEN OXIDE
compounds composed of hydrogen and carbon
VOLATILE ORGANIC CARBONS
90% of (?) emissions come from burning sulfur containing fossil fuels, such as coal, which may contain up to 6% sulfur.
SULFUR DIOXIDE
comprises solid particles or liquid droplets (aerosols) small enough to remain suspended in air.
PARTICULATE MATTERS
SOURCES OF AIR POLLUTION (4)
MOBILE SOURCES
POINT SOURCES
AREA SOURCES
NATURAL SOURCES
the largest source of air
pollutions it pertains to our
vehicles such as PUVs, PUJs,
tricycles etc.
MOBILE SOURCES
Sources that emits large amount of pollution in a location
POINT SOURCES
Made up of lots of smaller pollution sources that aren’t a big deal by themselves but when considered as a group can be.
AREA SOURCES
can be considerable at times, but unlike other sources, they rarely cause extreme air pollution.
NATURAL SOURCES
Contamination of water by an excess amount of substance that can cause harm to human beings
Water Pollution
According to the World
Health Organization, in 2008
approximately (?) people in the world (or 13% of world population) did not have access to safe drinking water.
880 million
DIFFERENT WATER BODIES (2)
LAKE
RIVER
is a body of water that is surrounded
by land.
LAKE
A freshwater that flows downhill from the
force of a gravity.
RIVER
SOURCES OF WATER POLLUTION (2)
POINT SOURCES
NONPOINT SOURCES
discharge their wastewater/effluent
directly to the receiving bodies of water.
POINT SOURCES
are the combination of pollutants from a large area rather than from specific identifiable sources.
NONPOINT SOURCES
resulting in
eutrophication and increased biological oxygen demand (BOD).
Untreated wastewater
RESULTS OF WATER POLLUTION (2)
CORAL REEF ACIDIFICATION
EUTROPHICATION
due to continuous and
rampant carbon emissions,
carbon dioxides react to the
water, resulting in the corals’
white color and later on deathof the corals
CORAL REEF ACIDIFICATION
Agricultural runoffs and
untreated wastewater from
restaurants were the primary
cause of eutrophication.
EUTROPHICATION
is the excessive, misdirected or invasive use of artificial outdoor lighting.
Light pollution
TYPES OF LIGHT POLLUTION (4)
GLARE
SKY GLOW
LIGHT TRESPASS
LIGHT CLUTTER
Visual impairment that
occurs when the light
source is brighter than the
light that your eyes used
to.
GLARE
Upward directed light
reflects on particles in the
sky reducing visibility of
stars.
SKY GLOW
The poor control of
outdoor lighting crosses
property lines and
detracts from property
values and our quality of
life.
LIGHT TRESPASS
is a bright,
confusing, and excessive
groupings of light
sources, commonly found
in over-urban areas.
LIGHT CLUTTER
EFFECTS OF LIGHT POLLUTION (4)
messing with our melatonin levels
contributing to sleeping disorders Reduction
increasing risks for obesity
sleep disorders
Is the disturbing or excessive noise that may harm the activity or balance of human and animal life
Noise Pollution
The word noise comes from the Latin word
Nausea
DIFFERENT SOURCES OF NOISE POLLUTION (2)
NATURAL NOISE
MAN-MADE NOISE
Noise that produced by nature
NATURAL NOISE
2 types of MAN-MADE NOISE
MAN-MADE INDOOR NOISE
MAN-MADE OUTDOOR NOISE
Sounds emitted from our households
MAN-MADE INDOOR NOISE
Social gathering/events generates too much noise and may affect the nearby households.
MAN-MADE OUTDOOR NOISE
types of MAN-MADE OUTDOOR NOISE (3)
SOCIAL EVENTS
INDUSTRIAL AND COMMERCIAL ACTIVITIES
TRANSPORTATION
EFFECTS OF NOISE POLLUTION (4)
Damaged brain and hearing power
Psychological disorders
Increased risk of cardiovascular diseases
Sleeping disorders
The discharge of waste heat via energy dissipation into cooling water and subsequently into nearby waterways.
Thermal Pollution
MAJOR SOURCES OF THERMAL POLLUTION (6)
1.) Fossil fuel electric power plants
2.) Nuclear fuel, electric power generating facilities
3.) Cooling operations associated with industrial manufacturing
4.) Earth’s surface temperatures
5.) CO and CO2 as products of combustion for greenhouse effect
6.) Hot water vapor
