  1. Air Pollution By: Rebekah Elmuza

  2. Air Pollution • The introduction of toxic chemicals into the atmosphere. • Damages natural environment. • Causes health problems in living things. • Classified as primary, secondary, and particulate pollutants.

  3. Primary Pollution • The emission of substances directly into the environment. • Volcanic-release ash. • Motor vehicles-carbon monoxide. • Factories-sulfur dioxide.

  4. Secondary Pollution • Not emitted directly to the air, water, or soil. • Formed when primary pollutants react in the atmosphere. • They are synthesized in the environment by: • chemical reactions such as nitrogen dioxide. • emitted chemicals such as ozone (gas & strong oxidant).

  5. Particulate Pollution • Complex mixture of small particles and liquid droplets. • Causes health problems • Two categories of particle pollution: • Inhalable coarse particles • Fine particles

  6. Ozone Depletion • The ozone is a gas that helps protect Earth from UV-Radiation. • Harmful substances involve: • Coolants • Foaming agents • Fire extinguishers • Solvents • Pesticides • Aerosol Propellants

  7. Acid Rain • Any form of precipitation with high levels of nitric and sulfuric acid. • Also occurs in the form of snow and fog. • Most causes are from the burning of fossil fuels, rotting vegetation, and erupting volcanoes. • Acid Rain effects: • Water acidity • Sinks into the soil • Damages forests • http://www.canadiangeographic.com/atlas/themes.aspx?id=SHIELD&sub=SHIELD_FEATURES_DELUGE&lang=En

  9. The Clean Air Act • Federal law designed to protect, improve, and regulate the nation’s air quality. • First created in 1970. • Helps stratospheric ozone layer. • Protects public well-being.

  10. In general, these are the most polluted places in the world since they are industrialized and have a careless attitude towards the environment. Some of the most polluted places in the world include: Dzerzinsk, Russia Kabwe, Zambia Haina, Dominican Republic Rudnaya Pristan and Dalnegorsk, Russia Mailuu-Suu, Kyrgystan World Pollution La Orova, Peru Ranipet, India Norilsk, Russia

  11. In 1986 Chernobyl Ukraine had a nuclear disaster which left the area uninhabitable. In Linfen China, air quality is poor due to the burning of coal. Examples

  12. United States Pollution • Top most polluted cities include: • Los Angeles, CA. • Bakersfield, CA. • Pittsburgh, PA. • Fresno, CA. • Birmingham, AL. • Detroit, MI. Los Angeles, CA Pittsburg, PA

  13. Acid Rain in the U.S. • This is a big concern in the eastern half of the U.S. • Occurs in industrialized and urbanized areas. • Most effected areas include: • New York • Pennsylvania • Maryland • Virginia

  14. Acid Rain Globally • Other areas affected: • Southeastern section of Canada (Toronto-Hamilton area) • Central Europe • Scandanavia (Sweden, Norway, Finland) • Asia (India and China) Europe

  15. Short-term effects include: Irritation in eyes, nose, and throat Headaches Nausea Allergic reactions Long-Term effects include: Chronic respiratory disease Lung cancer Heart disease Damage to brain, nerves, liver or kidneys Health Problems of Air Pollution
