    Air Pollution

    Definition of Air pollution


    Air pollution is the contamination of air
    due to the presence of substance in the
    atmosphere that are harmful to the
    health of humans and other living beings,
    or causing damage to the climate or to
    materials. Air pollution occurs when
    substances are released in excess of
    normal into the atmosphere.
    Types of pollutants
    The types of pollutants are gases,
    liquids, solid or various forms of energy
    and biological molecules. Sources of
    pollution include personal habits like
    cigarette smoking, industries,
    combustion of various substances and
    natural disasters like the discharge of
    hydrogen sulphide to the atmosphere i.e.
    release of hydrogen sulphide to the
    atmosphere from lake Nyossin
    Cameroon in 1994 which killed one
    thousand eight hundred people.
    Main causes of Air pollution. The main
    causes of air pollution are vehicle
    emissions, fuel oils and natural gas to
    heat, homes, by products of
    manufacturing and power generation,
    particularly coal fuelled power plants
    and fumes from chemical production
    are primary sources of human- made air
    pollution.
    Effects of Air pollution
    Long term health effect from air
    pollution includes heart disease, lung
    cancer, and respiratory diseases such
    as emphysema. It can also cause long
    term damage to people’s nerves, brain,
    kidneys, liver and other organs; scientist
    also suspects air pollutants can cause
    birth defects.
    Sources of Air pollution
    Personal habits. Personal habits like
    tobacco smoking, the resulting smoke is
    not only dangerous to the smoker but to
    others around them who then become
    passive smokers (including the child in
    the womb)
    Combustion. During combustion at
    home or in industry, smoke is produced
    which depend on the nature of material
    being burnt and method of burning.
    Smoke consists of unburnt particles of
    carbon-dioxide, carbon-monoxide grit,
    dust, sulphurdioxide and tar.
    Smoke has the capacity of reducing the
    amount of sunshine that reaches the
    surface of the earth. This may have
    serious effect on agriculture. Inhalation
    of smoke results in deposition of carbon
    particles in the lungs which can result in
    the risk of rhimtis, sinusitis, and
    bronchitis as well as cardiovascular
    diseases. Death result in the inhalation
    carbondioxide from fumes from exhaust
    of generators and automobile. The
    smoke also contains carcinogenic
    hydrocarbons and products of organic
    lead (capable of causing nephritis which
    may progress to kidney failure).
    Industrial production. During production
    of many materials large quantities of
    pollutants are released to the air.
    Example include
    a. Poisonous hydrogen sulphide
    from oil refining process as well as
    dye and rayon industries
    b. Pneumoconiosis or Dust Diseases.
    Example is silicosis when arises
    from inhaling of large quantity of
    silica, those at risk are miners,
    stonecutter, potters, glassmakers
    and blast sand. Another example is
    Asbestos is resulting from inhaling of
    asbestos particles.
    Prevention of Air pollution
     Avoid burning leaves, trash and
    other materials
     Avoid using gas powered lawn and
    garden equipment
     Reduce or climinate fireplace and
    wood stone use by maintaining
    your wood stove or fireplace
     Reduce the number of trips you
    take in car. Minimize air pollution
    from cars.
     Walk, bike or use public
    transportation
     Recycle and buy recycled products
     Eat local, organic produce and less
    meat
     Grow your own food
     By advocating the use of public
    transport and carpooling
     By avoiding wastage of electricity
    and practicing reuse and recycling
    of compatible products
     Drive your car less
     Keep your car in good engine
     Turn off your engine
     Don’t burn your garbage
     Limit backyard fire in the trees
     Switch to electric or hand- powered
    lawn equipment
     Use less energy.
