    Air pollution and your health Air pollution and your health Presentation Transcript

    • Air Pollution and Your Health Environmental Science
    • Air Pollution
      • Air pollution can cause serious health problems, especially for people who are very young, very old, or who have heart or lung problems.
      • Air pollution intensifies the effects of existing diseases such as emphysema, heart disease, and lung cancer
    • Short Term Effects of Air Pollution
      • Short-term effects of air pollution on people ’ s health range from minor headaches to more serious bronchitis and pneumonia
      • Air Pollution can also make asthma and emphysema worse for certain individuals.
      • Many short-term effects are reversible if exposure to air pollution decreases.
    • Long-Term Effects of Air Pollution
      • Long-term effects on
      • health include
      • emphysema, lung
      • cancer, and heart
      • disease.
      • Exposure to air pollution may worsen medical conditions suffered by older people and may damage the lungs of children.
    • Indoor Air Pollution
      • Often the air quality inside a building is worse than the air quality outside
      • Harmful compounds can be found in carpets, building materials, paints and furniture – especially when they are new
      • To best maintain the air quality indoors you should identify and remove the sources of harmful compounds
      • Mixing outdoor air with indoor air, is also necessary for good air quality.
    •  
    • Sick-Building Syndrome
      • Sick-building syndrome is a set of symptoms, such as headache, fatigue, eye irritation, and dizziness, that may affect workers in modern, airtight office buildings.
      • Sick-building syndrome is believed to be caused by indoor air pollutants.
      • Sick-building syndrome is most common in hot places where buildings are tightly sealed to keep out the heat.
    • Radon Gas
              • Radon gas is colorless, tasteless, odorless, and radioactive.
              • Radon seeps through cracks and holes in foundations where it adheres to dust particles.
      • People inhale the dust, there radon can destroy the genetic material in cells that line the air passages.
      • The damage can lead to cancer, especially among smokers.
    • Asbestos
      • Before the 1970 ’ s asbestos
      • was used as an insulator
      • and fire retardant in buildings.
      • Asbestos fibers can cut and
      • scar the lungs, causing the
      • disease asbestosis.
      • Victims of the disease have more and more difficulty breathing and may eventually die of heart failure.
    • Noise Pollution
      • Health problems that can be caused by noise pollution include loss of hearing, high blood pressure, and stress.
      • Noise can also cause loss of sleep, which may lead decreased productivity at work and in the classroom
      • A decibel is the most common unit used to measure loudness, and is abbreviated dB.
    • Light Pollution
      • Light pollution doesn ’ t directly
      • effect human health, but it does
      • negatively affect our environment.
      • The most important environmental concern of inefficient lighting is energy waste.
      • Energy is wasted when a light is directed upward into the night sky and lost to space. Examples include lighting on billboards, poor-quality street lights, and the lighting of building exteriors.
