1. Air Pollution and Your Health Environmental Science Spring 2013

2. 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 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 Air pollution intensifies the effects of existing diseases such as emphysema, heart disease, and lung cancer

3. 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 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. Air Pollution can also make asthma and emphysema worse for certain individuals. Many short-term effects are reversible if exposure to air pollution decreases. Many short-term effects are reversible if exposure to air pollution decreases.

4. 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.

5. Indoor Air Pollution Often the air quality inside a building is worse than the air quality outside 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 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 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. Mixing outdoor air with indoor air, is also necessary for good air quality.

7. 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.

8. Radon Gas  Radon gas is colorless, tasteless, odorless, and radioactive.  Radon seeps through cracks in the foundation 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.

9. 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.

10. 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 (dB).

11. 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.
