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.

12
Pollutants
  • 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.

RADON
  • 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.

21
RADON
  • 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.

22
Radon
  • Radioactive radon-222
  • Lung cancer threat
  • Occurs in certain areas based on geology
  • Associated with uranium and organic material in
    rock

  • 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

30
Sulfur 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
    Ph,Building simple fragile eroded.
  • Eyes painful, damage the lungs

31
Nitrogen Dioxide
  • Grey gas to orange
  • Brochitis cancer respiratory organ.
  • Damage lung tissue
  • Eyes irritant
  • Decreasing resistance Children of Flu
  • Late rain water acid rain Forming
  • 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

34
Carbon 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.

35
Dust (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

37

  • 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

38
OZON 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

40
OZON 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.

41
EFFECTS OF AIR POLLUTION ON THE ENVIRONMENT
  • Sources - the construction, demolition, soil
    erosion, dust asbestos disposal
  • Classification - human health, vegetation, animal

42
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.

43
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.

44
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.

45
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

46
The Greenhouse Effect
47
The Greenhouse Effect
48
GREENHOUSE PHENOMENON
49
GREENHOUSE PHENOMENON
  • 1824 - a French scientists - Jean Baptisle
    Fourier.
  • GreenhouseWithout the greenhouse effect, earth
    surface temperatures fell to -180C

50
GREENHOUSE
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.

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
  • Burning fuel
  • Forest fires
  • Felling of forests and livelihoods
  • Widespread burning of rubbish
  • Fuel combustion in industry
  • Motor vehicles
  • 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.

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 0.6C (1.1F) 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

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 doesnt
    happen)

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.

  • 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 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
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 _at_ 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
    _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.

86
