  1. Chlorinated Dibenzo-p-dioxins By: Michael Null, James Ogletree, and Cody Christianson

  2. What is it? • The EPA considers it a CDD • A CDD is a family of 75 different compounds • commonly referred to as polychlorinated dioxins • The CDD family is divided into eight groups of chemicals based on the number of chlorine atoms in the compound

  3. Where is it? • CDDs are released during • Combustion of fossil fuels • During incineration processes (municipal and medical solid waste and hazardous waste incineration). • Herbicides and pesticides • Burning anything that has chlorine will release certain CDDs • Also found naturally in the environment • Agent Orange

  4. How you ingest it • Naturally we ingest somewhere between a nanogram (one billionth of a gram) and a picogram (one trillionth of a gram) • Due to breathing or eating meat/dairy products or contact • Stored in your fat and liver • Little is known about the breakdown in the body

  5. Detection • There is no quick way to detect it, since it is stored in your fat it is hard to test for • Blood test after immediate exposure

  6. Regulation • Federal agencies that develop regulations for toxic substances include the • Environmental Protection Agency (EPA) • The Occupational Safety and Health Administration (OSHA) • The Food and Drug Administration (FDA) • Still collecting information on affects and where it is

  7. How it affects your health • Chloracne (a cross between acne and a burn) • Liver failure • Risk of cancer

  8. Other CDDs • Different amounts of chlorine atoms make up the groups • More deadly versions such as tetrachlorinated • In certain species, 2,3,7,8-TCDD is especially harmful and can cause death after a single exposure to small amounts. Before death, animals may lose as much as 40% or more of their body weight following a single dose of 2,3,7,8-TCDD

  9. Agent Orange • Most famous CDD • Herbicide made for the U.S. military • Used during operation ranch hand in Vietnam war • 20 million gallons used during the war • Includes TCDD in the mixture

  10. Health Affects • 4.8 million people in Vietnam were exposed • Many health problems such as mental defects, extra fingers and toes, cleft palate are some of the symptoms. • Studies of veterans who served in the South during the war have increased rates of cancer, nerve, digestive, skin and respiratory disorders.
