  1. Chlorofluorocarbons By Jenny & Brianna

  2. What are CFCs? • Carbon + Halogens (i.e. Fluorine, Chlorine) • Types • Properties and Characteristics • Applications • Causes & Effects www.cartoonstock.com users.bentonville.k12.ar.us

  3. Most harmful CFC's and Halons • · CFC-11 (Freon) • CCl3F -- ODP 1.0 • · CFC-12 • CCl2F2 -- ODP 0.82 • · CFC-113 • C2Cl3F3 -- ODP 0.90 • · CFC-114 • C2Cl2F4 -- ODP 0.85 • · CFC-115 • C2ClF5 -- ODP 0.40 • ·Halon 1211 • CF2ClBr -- ODP 5.1 • ·Halon 1301 • CF3Br -- ODP 12 • ·Halon 2402 • CF2BrCF2Br -- ODP 6.2 http://www.epa.gov

  4. How are CFCs measured? • Satellites • Ground-based methods • Balloons http://www.beckman.com www.solarlight.com http://www.atm.ch.cam.ac.uk http://soer.justice.tas.gov.au

  5. Ozone Concentration At the poles, vortex of winds isolate the stratosphere. At very low temperatures, clouds of ice, nitric acid, and sulfuric acid forms. The surfaces of the crystals react to release CFCs. http://www.theozonehole.com/ www.noaanews.noaa.gov

  6. How Do People Contribute to CFCs? • Products and Uses http://www.uwm.edu http://www.bigappledirect.com http://www.orlandosentinel.com http://www.maplin.co.uk http://img.alibaba.com

  7. Global CFC Production From 1950 to 1987, the production of CFC was on an increase. After the Montreal Protocol in 1987, the regulations significantly decreased CFC production. http://maps.grida.no

  8. CFCs Chemistry • Bonds • Reactions http://www.cotf.edu http://www.centerforsustainability.org http://www.esm.ucsb.edu

  9. Path of CFCs A brief overview of the beginning and consequences of CFCs. http://www.ozonelayer.noaa.gov/science/StratO3.jpeg

  10. What Can You Do to Help? • Different chemical compound • Recycling • Avoid products containing CFCs http://www.petefreitag.com cdn.overstock.com http://www.zencommandments.com/store/index.php?main_page=shopping_cart http://www.doart.co.uk
