Title: Indoor Air Pollution Has Become A Growing Health Concern


1
Indoor Air Pollution Has Become A Growing Health
Concern
2
  • According to Global Health Risks, Mortality and
    burden of disease attributable to selected major
    risks indoor air pollution is responsible for
    2.7 of the global burden of disease. Both
    health experts and consumers have now become
    increasingly concerned about the increase in air
    pollution indoors and its impact on human health.

3
  • Indoor air quality (IAQ) refers to the air
    quality within and around buildings and
    structures. Exposure to indoor air pollution is
    determined by the concentrations of pollutants in
    the indoor environment and the amount of time
    that is spent in the indoor environment that has
    poor quality air. Tiny airborne contaminants with
    a diameter of 10 microns or less can penetrate
    deep in the lungs when inhaled and have harmful
    effects on human health. Women and children that
    spend a lot of time in the home are particularly
    at high risk of exposure to harmful airborne
    particles.

4
  • Environmental tobacco smoke (ETS) is another
    health hazard. ET is the mixture of smoke that
    comes from the burning end of a cigarette, cigar,
    or pipe as well as smoke exhaled by the smoker.
    The smoke produced is a blend of over 4,000
    compounds with more than 40 of the compounds
    identified as a cause of cancer in humans or
    animals. Infants and young children exposed to
    secondhand smoke are at increased risk of lower
    respiratory tract infections such as bronchitis
    and pneumonia, and they are more likely to have
    symptoms of respiratory irritation such as excess
    phlegm, chronic coughing, and wheezing.

5
  • Poor indoor air quality can contribute to the
    development of a number of health problems.
    Chronic respiratory illnesses such as lung
    disease, asthma, and bronchitis can be worsened
    for those afflicted with such health conditions.
    People can also develop such conditions when
    constantly exposed to poor quality indoor air.
    There can also be biological contaminants in the
    home contributing to poor quality indoor air such
    as mould, mildew, and bacteria resulting from a
    moist environment. People living in buildings
    with mould are more likely to suffer from
    symptoms like wheezing, runny eyes and nose,
    coughing, chest congestion, chronic coughing, and
    other allergic reactions. Exposure to mould can
    also trigger asthma symptoms. Molds and mildews
    release disease-causing toxins.

6
  • There are a number of other symptoms indicating
    exposure to poor quality indoor air which
    include headaches, dizziness, migraines, nasal
    congestion, nausea, digestive problems, insomnia,
    irritability, dry and pale skin, and lethargy. As
    well, some types of infectious illnesses such as
    influenza, measles, and chicken pox are
    transmitted through the air. In recent years,
    there has been a growing body of research
    compiled that is demonstrating that the air
    within homes and other buildings can be more
    polluted than the outdoor air and other research
    has found that people now spend about 90 percent
    of their time indoors. As a result, the risk of
    disease and illness is now much higher for those
    constantly exposed to air pollution indoors. For
    this reason, health organizations and government
    agencies are offering guides and manuals on
    improving the quality of air within homes and
    buildings.

  • Today, consumers can find a wealth of
    information online about the various ways they
    can reduce or eliminate indoor air pollution.
    Solutions to improving indoor air quality can
    range from something simple like using chemical
    free cleaners, making the home smoke free,
    putting a humidifier in the basement, changing
    air filters frequently, and making sure there is
    adequate ventilation throughout the home. Or,
    people can be more proactive by getting their
    indoor air tested for contaminants, hiring
    professional duct cleaners to give their air
    ducts a thorough cleaning, replacing all
    household and personal care products containing
    chemicals with more natural products, and taking
    steps to remove common sources of pollution, or
    reduce their emissions. This can include removing
    furnishings containing harmful chemicals such as
    furniture made of certain pressed wood, removing
    old and damp carpets, getting the fireplace
    thoroughly cleaned, and more. When taking both
    small and big steps to improve the quality of
    indoor air, you and your family will definitely
    see an improvement in your health and well being.
