6DEFINITION
- 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

11Pollutants
- 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.
12Pollutants
- 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.

20RADON
- Radon is a chemical element in the periodic table
that has the symbol Rn and atomic number 86. - Noble gas that is formed by the disintegration of
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.
21RADON
- Radioactive gas found in soil earth bricks that
exist in the original form of radium that is
damaged - such as the decay products of uranium. - Progeny, decay products _at_ daughtera.
- Damage lung tissue lung cancer.
- Smokers are likely to die from this cancer.

29- Sulfur Dioxide
- produced when coal and fuel oil are burned
- present in power plant exhaust
- narrows the airway, causing wheezing and
shortness of breath, especially in those with
asthma
30Sulfur Dioxide
- Many Industrial meta-orel removing, cleaning of
oil, Pulp Paper Manufacturing
IndustriesCharcoal is a substance that contains
sulfur. - When burning sulfur will combine with oxygen to
produce sulfur dioxide around the equationS
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.
- Gas no color
- Strong odor poked
- Easy to late rain water mould acid rain(human
skin, damage of iron steel, low land

- Key components in forming vague Photochemical
32- Nitrogen Dioxide
- reddish, brown gas
- produced when nitric oxide combines with oxygen
in the atmosphere - present in car exhaust and power plants
- affects lungs and causes wheezing increases
chance of respiratory infection
33- Carbon Monoxide
- colorless, odorless
- produced when carbon does not burn in fossil
fuels - present in car exhaust
- deprives body of O2 causing headaches, fatigue,
and impaired vision
34Carbon Monoxide
- Occurs when the internal combustion engine can
not burn the fuel completely. - 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.
- Combines with hemoglobin to form
karboksihemoglobinCauses lack of oxygen, can
cause death. - Moisturize the brain, dizziness
headaches.Product gas is not completely carbon
compounds. - Resulting from car exhaustareas of traffic
congestionCar Garage under the building
closed.
35Dust (particular matter)
- Solid particles are trapped with gas directly
from the material being diproses.Contohnya coal
cement. - Dust is separated from the fragments of the
parent in the mechanical processes, such as
sawdust. - Consisting of large particles such substances
Used trapped in coal-cleaning operations.
- Can deface buildings
- Asthma attacks for asthma patients.
- Clogging leaf of stoma cover-reduced rate of
photosynthesis.
36- Particulate Matter
- particles of different sizes and structures that
are released into the atmosphere - present in many sources including fossil fuels,
dust, smoke, fog, etc. - can build up in respiratory system
- aggravates heart and lung disease increases risk
of respiratory infection
37Lead (Plumbum)
- Retardation caused brain defects in children.
- Reduce the ability of the hand foot
coordination, coma and death _at_ disrupt the body's
ability to build new blood cells. - Suspended matter.
- Sole source of car-exhaust
- Except with the nearest non-ferrous smelting
38OZON PHOTOCHEMICHAL SMOG
39- Ground Level Ozone
- at upper level, ozone shields Earth from suns
harmful UV rays - at ground level, ozone is harmful pollutants
- formed from car, power and chemical plant exhaust
- irritate respiratory system and asthma reduces
lung function by inflaming and damaging lining of
lungs
40OZON PHOTOCHEMICHAL SMOG
- The main contributor to car-exhaust
- Oxides of nitrogen are formed in the combustion
of gasoline fuel released into the atmosphere
react with sunlight, ozone. - Ozone reacts with hydrocarbons to form a series
compound include aldehydes organic acids.
41EFFECTS OF AIR POLLUTION ON THE ENVIRONMENT
- Sources - the construction, demolition, soil
erosion, dust asbestos disposal - Classification - human health, vegetation, animal
42EFFECTS 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.
43EFFECTS 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.
44POLLUTION 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.
45EFFECTS 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
46The Greenhouse Effect
47The Greenhouse Effect
48GREENHOUSE PHENOMENON
49GREENHOUSE PHENOMENON
- 1824 - a French scientists - Jean Baptisle
Fourier. - GreenhouseWithout the greenhouse effect, earth
surface temperatures fell to -180C
50GREENHOUSE
51GREENHOUSE
- 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.
52GREENHOUSE
- 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.
53GREENHOUSE 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.
54GREEN 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.

56SOURCES 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 - Burning fuel
- Forest fires
- Felling of forests and livelihoods
- Widespread burning of rubbish
- Fuel combustion in industry
- Motor vehicles
- The use of Chlorofluorocarbon (CFC)

58SEA 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.

61CLIMATE 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.
62Evidence for Climate Change
- 20th C was hottest in the past 1000 years
- Global temp has risen 0.6C (1.1F) since 1861
- 16 warmest years on record since 1980, 10 warmest
since 1990 - Glaciers and sea ice are melting
- Sea level has risen 100-200 cm over 20th C
63Past Climate Changes
64CO2 and temperature from ice cores
65Solutions 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 doesnt
happen)
66JOHOR FLOODS (2006 2011)
67AFFECTED 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.
68DAILY 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.
69DISRUPTED AGRICULTURAL PRODUCTIVITY
- Production of crops and livestock declined due to
lack of water and heat.
70measures to overcome
- Re-afforestation
- Recycling (GREEN DOT)
- Awareness campaign
- The use of environmentally friendly energy
sources.

80- API Air Pollution Index
- Indicates whether pollutant levels in air may
cause health concerns. - Ranges from 0 (least concern) to 500 (greatest
concern)
81Air 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.
82MEASUREMENT OF AIR QUALITY
Pure Air - Air semulajd but does not exist in
the natural environmentthe beginning of the
first generationEquipment 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.Disadvantag
es - difficult to use, slow inaccurate
83Second 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 _at_ response with it.
84Third Generation
- To produce a continuous reading.
- Continuous graph showing the levels of various
pollutants is obtained by measuring spontaneous
85measurement 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
_at_ 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.
