ENVIRONMENTAL
POLLUTION
AND CONTROL
AIR POLLUTION
•Any visible or invisible particle or
gas found in the air that is not part of
the original, normal composition.
Natural:forest fires, pollen, dust
storm
Unnatural: man-made; coal, wood
and other fuels used in cars, homes,
and factories for energy
DEFINITION
 There is a gas, liquid or particles contained in the
air so that the change and affect the life or other
materials.
 The materials are suspended in the air and a
negative impact on humans, plants and animals.
 This is due to these materials will enter the body
through breathing and can block the flow of
oxygen into the blood vessels.
 This can cause various diseases such as cramps,
cancer, asthma, cramps, and anemia.
Dust, smoke, mist, vapor or other substances that
can block eyesight is different form of air pollution
Pollutants
Pollutants can be classified as either
primary or secondary
primary pollutants
are substances directly emitted from a
process, such as the carbon monoxide
gas from a motor vehicle exhaust or
sulfur dioxide released from factories.
Secondary pollutants
are not emitted directly. Rather, they form in the
air when primary pollutants react or interact. An
important example of a secondary pollutant is
ground level ozone.

radium, radon is the heaviest gases and is considered
a health hazard.
 The most stable isotope is Rn-222 which has a half
life of 3.8 days and used in radiotherapy.
Radon gas can accumulate in homes and cause lung
cancer [1], causing potentially 20,000 deaths in
Europe alone each year.

Charcoal is a substance that
contains sulfur.
 When burning sulfur will
combine with oxygen to
produce sulfur dioxide
around the equation:
S + 2O2 ----------- SO4
 Sulfur dioxide is then
combined with hydrogen
ions in the vapor in the air
and form acids sulfurous.
 In addition, carbon dioxide
combines with hydrogen ions
and form carbonic acid.

 Carbon monoxide is a
dangerous gas and can be
fatal if inhaled in a long-
term.
 Burning of fossil fuels like
coal and oil is the main
cause of air pollution.
 Fuel is also organic and has
the element carbon.
 Thus, incomplete combustion
produces carbon monoxide.

EFFECTS OF POLLUTION ON
HUMAN HEALTH
 The main effect of air
pollution on humans is
the respiratory system.
 Gases such as carbon
monoxide will poison
the transport of oxygen
in the blood system will
slow human reaction
and the effects can lead
to drowsiness, asthma
and reduced lung
function.
EFFECTS OF POLLUTION ON
HUMAN HEALTH
 Pollutants such as nitrogen oxide can cause
pulmonary edema and bleeding.
 Pollutants such as ozone gas can cause
irritation to cause inflammation of the lungs
and the ability to move.
 Dust, smoke, mist, vapor or other materials
are also prevents eye sight and also affect
the human eye.
 Study World Health Organization (WHO) state
of three million people die every year due to
air pollution.
 It is three times higher than the number of
deaths from vehicle accidents.
POLLUTION EFFECTS ON
VEGETATION
 The effects of the plant are damaged, such as
necrosis (loss of leaves), chlorotic (change colors),
and stunted growth.
 This effect will cause the earth lack of food resources
and economic section of the population is affected.
 Sulfur Dioxide - damage to the sheets - of cotton,
wheat.
 OZONE - leaf spots - tomatoes, beans, spinach &
potato.
 Flouride - End of burning leaves - the broadleaf trees.
EFFECTS OF POLLUTION ON
ANIMALS
 Animals become endangered or dying as a result of
air pollution.
 This is because of the air entering the lungs of the
animal and plant sources of food contaminated with
the effects of air pollution.
 Most rapidly through the food
 Animals eat the plants vulnerable to food poisoning.
 Arsenic (metal lead)
 Animals exposed to contaminated sulfur dioxide gas.
Effect of fluoride harm cattle & sheep
The Greenhouse Effect
GREENHOUSE PHENOMENON
 1824 - a French scientists - Jean
Baptisle Fourier.
 Greenhouse
Without the greenhouse effect, earth
surface temperatures fell to -180C
GREENHOUSE PHENOMENON
GREENHOUSE
GREENHOUSE
 Greenhouse is a building made of glass or
plastic that allows planting of a protected and
controlled.
 The heat from the heat penetrates the
transparent structure of vegetation and soil in
it.
 In addition, the air inside is heated and has
remained without can escape out of this
building.
GREENHOUSE
 The building was constructed in various forms and roles.
In an industry desperate farmers, for example, it was
built with big size and equipped with modern equipment
for multi-monitor and promote the growth of plants in it.
 Glass or plastic are also used to work as an intermediary
that allows the transfer (or "liberation") of radiation at
certain frequencies.
 The result is that, in the energy "trapped" in it for
heating plants, and can not freely exit from the
greenhouse.
Greenhouse is also used in industry and also for research
purposes.
GREENHOUSE
PHENOMENON PROCESS
 Greenhouse effect occurs when the
composition of greenhouse gases such as
carbon dioxide, carbon monoxide, nitrogen
dioxide rises above normal levels.
 When the composition is increased, the
molecules of gas, which is heat storage, will
trap heat and slow down the process of heat
release.
GREEN HOUSE EFFECT
GLOBAL
 Global greenhouse effect occurs when, in the
infrared solar radiation entering the earth's
atmosphere are not adequately reflected by
normal due to the greenhouse effect.
 This will lead to gradual global warming, and
areas experiencing severe pollution will be
affected by more severe.
 The implications of global warming will cause
ice at both poles of the earth will experience
dilution and cause an increase in sea level.
SOURCES OF GREEN HOUSE
EFFECT
 Source of the greenhouse effect is an increase in
atmospheric carbon dioxide.
 Increase in the concentration of carbon dioxide in the
atmosphere caused by human activities such as:
a) Burning fuel
b) Forest fires
c) Felling of forests and livelihoods
d) Widespread burning of rubbish
e) Fuel combustion in industry
f) Motor vehicles
g) The use of Chlorofluorocarbon (CFC)

SEA LEVEL RISE
 Sea level rise in the Arctic and Antarctica is
caused by melting chunks of ice that caused
flooding coastal areas, as occurs in coastal
Bangladesh.
 spill in sea water to agricultural areas and
increase the salinity (saltiness) of land.
 Makes it less suitable for agriculture.
 Will submerge low-lying areas and cause
flooding.
TSUNAMI (2004)
CLIMATE CHANGE
 Higher atmospheric temperature causes evaporation
of water occurs very quickly. Consequently, the
occurrence of droughts and floods is uncertain.
 Changes in the wind and currents causing natural
disasters such as storms (RITA, Katrina, Wilma) and
hurricanes.
 Extreme climatic events where droughts and floods
occur unexpectedly, such as in Africa. This reduces
the production of forest and agriculture.
 Changes in rainfall and water resources, transforming
the availability of water.
 It bring problems to the agriculture and reforestation.
Evidence for Climate Change
1. 20th C was hottest in the past 1000 years
2. Global temp has risen 0.6°C (1.1°F) since
1861
3. 16 warmest years on record since 1980, 10
warmest since 1990
4. Glaciers and sea ice are melting
5. Sea level has risen 100-200 cm over 20th C
Past Climate Changes
CO2 and temperature from ice cores
Solutions: Dealing with the Threat
of Climate Change
Options
• Do more research before acting
– “wait and see” (current US
strategy)
• Act now to reduce risks
because global warming would
have severe impacts
• Act now in same way to reduce
risks of global warming
because it has other benefits to
environment and society (even
if warming doesn’t happen)
JOHOR FLOODS (2006 & 2011)
AFFECTED HUMAN HEALTH
 Changes in temperature can cause the
heat wave in some places and people,
especially the older population may
have heatstroke.
 Lack of fresh water and flooding can
cause contaminated water used and
lead to diarrhea.
DAILY ACTIVITIES AND HUMAN
SETTLEMENT UNINTERRUPTED
 Transfer of climate zones and the movement
of sea water and flooding can affect fishing
and other aquatic life.
 Natural disasters such as storms and
droughts also cause electrical interference.
 People living in coastal areas have sometimes
placed within the other because of flooding.
DISRUPTED AGRICULTURAL
PRODUCTIVITY
 Production of crops and livestock
declined due to lack of water and heat.
measures to overcome
 Re-afforestation
 Recycling (GREEN DOT)
 Awareness campaign
 The use of environmentally friendly
energy sources.

MEASUREMENT OF AIR
QUALITY
*Pure Air - Air semulajd but does not exist in
the natural environment
*the beginning of the first generation
Equipment needed to get quantitative
information about the air built by engineers &
scientists controlling air pollution.
Advantages - Quick, inexpensive & does not
require external power to operate.
Disadvantages - difficult to use, slow &
inaccurate
Second Generation
•Expanded when the data are more accurate & fast
required
•Using a power source, usually electric pumps to
move air & unttk may mensampel with more air in
a shorter time.
•Gas measurement technique typically involves wet
chemistry in which the gas is dissolved in the fluid
collector @ response with it.
Third Generation
•To produce a continuous reading.
•Continuous graph showing the levels
of various pollutants is obtained by
measuring spontaneous
measurement of particulate
•The first generation of devices for measuring particulates involves
measuring the amount of dust deposited on the earth.
The measurement of dust fall is the easiest method to measure air
quality.
•Whether the dust is collected in open containers @ the sticky tape is
placed around the jar.
•Sampling period to maturity is usually 30 days, usually sticky tape
can be read within 7 days & provide a qualitative indicator of the
particulate pollution.
•Dust fall jar dried to remove moisture & weighed to determine the
amount of dust in the blender, usually reported in tons (2,000 lb) of
dust per square mile settle within 30 days.
clean filter weight is 10:00g. After 24 hours in the hi-vol
sampler, dust filter and weighs 10.10 g. Air flow on the
surface & final test period was 60 & 40 ka3/min,
respectively. What is the concentration of particulates?
The weight of particulates (dust):
= (10:10 to 10:00) g x 106μg / g
= 0.1 x 106μg
The average air flow:
= (60 + 40) / 2 = 50 ka3/min
Amount of air through the filter:
= 50 ka3/min x 60 min / hour x 24 hours / day x 1 day
= 72.000 ft3
= 72.000 ft3 x 3.28 x 10-3 m3/kaki3
= 2038 m3
Total suspended particles:
= (0.1 x 106μg) / 2038 m3
= 49 6μg) / m3
Thank you

  • 49.  1824 - a French scientists - Jean Baptisle Fourier.  Greenhouse Without the greenhouse effect, earth surface temperatures fell to -180C GREENHOUSE PHENOMENON
  • 51. GREENHOUSE  Greenhouse is a building made of glass or plastic that allows planting of a protected and controlled.  The heat from the heat penetrates the transparent structure of vegetation and soil in it.  In addition, the air inside is heated and has remained without can escape out of this building.
  • 52. GREENHOUSE  The building was constructed in various forms and roles. In an industry desperate farmers, for example, it was built with big size and equipped with modern equipment for multi-monitor and promote the growth of plants in it.  Glass or plastic are also used to work as an intermediary that allows the transfer (or "liberation") of radiation at certain frequencies.  The result is that, in the energy "trapped" in it for heating plants, and can not freely exit from the greenhouse. Greenhouse is also used in industry and also for research purposes.
  • 53. GREENHOUSE PHENOMENON PROCESS  Greenhouse effect occurs when the composition of greenhouse gases such as carbon dioxide, carbon monoxide, nitrogen dioxide rises above normal levels.  When the composition is increased, the molecules of gas, which is heat storage, will trap heat and slow down the process of heat release.
  • 54. GREEN HOUSE EFFECT GLOBAL  Global greenhouse effect occurs when, in the infrared solar radiation entering the earth's atmosphere are not adequately reflected by normal due to the greenhouse effect.  This will lead to gradual global warming, and areas experiencing severe pollution will be affected by more severe.  The implications of global warming will cause ice at both poles of the earth will experience dilution and cause an increase in sea level.
  • 55.
  • 56. SOURCES OF GREEN HOUSE EFFECT  Source of the greenhouse effect is an increase in atmospheric carbon dioxide.  Increase in the concentration of carbon dioxide in the atmosphere caused by human activities such as: a) Burning fuel b) Forest fires c) Felling of forests and livelihoods d) Widespread burning of rubbish e) Fuel combustion in industry f) Motor vehicles g) The use of Chlorofluorocarbon (CFC)
  • 58. SEA LEVEL RISE  Sea level rise in the Arctic and Antarctica is caused by melting chunks of ice that caused flooding coastal areas, as occurs in coastal Bangladesh.  spill in sea water to agricultural areas and increase the salinity (saltiness) of land.  Makes it less suitable for agriculture.  Will submerge low-lying areas and cause flooding.
  • 59.
  • 61. CLIMATE CHANGE  Higher atmospheric temperature causes evaporation of water occurs very quickly. Consequently, the occurrence of droughts and floods is uncertain.  Changes in the wind and currents causing natural disasters such as storms (RITA, Katrina, Wilma) and hurricanes.  Extreme climatic events where droughts and floods occur unexpectedly, such as in Africa. This reduces the production of forest and agriculture.  Changes in rainfall and water resources, transforming the availability of water.  It bring problems to the agriculture and reforestation.
  • 62. Evidence for Climate Change 1. 20th C was hottest in the past 1000 years 2. Global temp has risen 0.6°C (1.1°F) since 1861 3. 16 warmest years on record since 1980, 10 warmest since 1990 4. Glaciers and sea ice are melting 5. Sea level has risen 100-200 cm over 20th C
  • 64. CO2 and temperature from ice cores
  • 65. Solutions: Dealing with the Threat of Climate Change Options • Do more research before acting – “wait and see” (current US strategy) • Act now to reduce risks because global warming would have severe impacts • Act now in same way to reduce risks of global warming because it has other benefits to environment and society (even if warming doesn’t happen)
  • 67. AFFECTED HUMAN HEALTH  Changes in temperature can cause the heat wave in some places and people, especially the older population may have heatstroke.  Lack of fresh water and flooding can cause contaminated water used and lead to diarrhea.
  • 68. DAILY ACTIVITIES AND HUMAN SETTLEMENT UNINTERRUPTED  Transfer of climate zones and the movement of sea water and flooding can affect fishing and other aquatic life.  Natural disasters such as storms and droughts also cause electrical interference.  People living in coastal areas have sometimes placed within the other because of flooding.
  • 69. DISRUPTED AGRICULTURAL PRODUCTIVITY  Production of crops and livestock declined due to lack of water and heat.
  • 70. measures to overcome  Re-afforestation  Recycling (GREEN DOT)  Awareness campaign  The use of environmentally friendly energy sources.

  • 75. Loss of the Ozone Layer: Reasons for Concern • Increased incidence and severity of sunburn • Increase in eye cataracts • Increased incidence of skin cancer • Immune system suppression • Increase in acid deposition • Lower crop yields and decline in productivity
  • 77. Solutions: Protecting the Ozone Layer • CFC substitutes • Montreal Protocol 1987 • Copenhagen Protocol 1992 • both signed by 177 countries • CFCs take 10-20 years to get to the stratosphere • CFCs take 65-385 years to break down
  • 80. API: Air Pollution Index •Indicates whether pollutant levels in air may cause health concerns. •Ranges from 0 (least concern) to 500 (greatest concern)
  • 81. Air Quality Air Pollution Index Protect Your Health Good 0-50 No health impacts are expected when air quality is in this range. Moderate 51-100 Unusually sensitive people should consider limiting prolonged outdoor exertion. Unhealthy for Sensitive Groups 101-150 Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. Unhealthy 151-200 Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion, everyone else, especially children should limit prolonged outdoor excertion. Very Unhealthy (Alert) 201-300 Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion everyone else, especially children, should limit outdoor exertion.
  • 82. MEASUREMENT OF AIR QUALITY *Pure Air - Air semulajd but does not exist in the natural environment *the beginning of the first generation Equipment needed to get quantitative information about the air built by engineers & scientists controlling air pollution. Advantages - Quick, inexpensive & does not require external power to operate. Disadvantages - difficult to use, slow & inaccurate
  • 83. Second Generation •Expanded when the data are more accurate & fast required •Using a power source, usually electric pumps to move air & unttk may mensampel with more air in a shorter time. •Gas measurement technique typically involves wet chemistry in which the gas is dissolved in the fluid collector @ response with it.
  • 84. Third Generation •To produce a continuous reading. •Continuous graph showing the levels of various pollutants is obtained by measuring spontaneous
  • 85. measurement of particulate •The first generation of devices for measuring particulates involves measuring the amount of dust deposited on the earth. The measurement of dust fall is the easiest method to measure air quality. •Whether the dust is collected in open containers @ the sticky tape is placed around the jar. •Sampling period to maturity is usually 30 days, usually sticky tape can be read within 7 days & provide a qualitative indicator of the particulate pollution. •Dust fall jar dried to remove moisture & weighed to determine the amount of dust in the blender, usually reported in tons (2,000 lb) of dust per square mile settle within 30 days.
  • 86. clean filter weight is 10:00g. After 24 hours in the hi-vol sampler, dust filter and weighs 10.10 g. Air flow on the surface & final test period was 60 & 40 ka3/min, respectively. What is the concentration of particulates? The weight of particulates (dust): = (10:10 to 10:00) g x 106μg / g = 0.1 x 106μg The average air flow: = (60 + 40) / 2 = 50 ka3/min Amount of air through the filter: = 50 ka3/min x 60 min / hour x 24 hours / day x 1 day = 72.000 ft3 = 72.000 ft3 x 3.28 x 10-3 m3/kaki3 = 2038 m3 Total suspended particles: = (0.1 x 106μg) / 2038 m3 = 49 6μg) / m3
