Air pollution and your health

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