Transcript

  • 1. acid rain anddeforestation | causes, effects and impacts<br />Luis Paulo Carneiro & Ricardo Coqueiro<br />Wizard University <br />#seminar 01| Sao Paolo, August, 26th-10<br />
  • 2. Acid rain<br />By Luiz Paulo CARNEIRO<br />ChemicalEngineer, specializing in Environmental<br />
  • 3. How Acid RainWorks<br />Acid rain occurs mostly in the Northern Hemisphere <br />Acid rain, also known as acid deposition, is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)from power plants, cars and factories. <br />SO2 / NOx + H2O-> H2SO4 / HNO3<br />
  • 4. The pH of Acid Rain<br />Express the acidity of acid rain using the pH scale. <br />The scale defines a solution's acidity, neutrality or alkalinity based on its concentration of hydrogen ions. ( 0 – 14 pH)<br />Acids – pH > 7,0<br />Most life is comfortable at a near- neutral pH (7,0<br />
  • 5. The pH of Acid Rain<br />Acidrain - pH of 5.0 orless. Mostaciddeposition ranges from pH 4.3 to 5.0 <br />
  • 6. The Effects of Acid Rain<br />
  • 7. The Effects of Acid Rain<br />Ex: Oldbuildings, monumentstombstones, automotivepaint<br />
  • 8. The Effects of Acid Rain<br />Effects for our health<br />Sulfate (SO4), nitrate (NO3) particulates of dry deposition can ­cause asthma, bronchitis and heart problems. <br />The NOx in acid deposition also reacts with volatile organic compounds (VOCs) to form ground-level ozone (O3). Ozone, or smog, aggravates and weakens the respiratory system. <br />
  • 9. DEFORESTATION<br />By Ricardo COQUEIRO<br />Administrator , MBA in Human Resources<br />
  • 10. What is Deforestation?<br />Is a process of cutting trees to make spaces frees for pastures, industries, households of the ever-increasing human population;<br />
  • 11. What are the Causes of Deforestation?<br />
  • 12. What are the Causes of Deforestation?<br />To Create Grazing Land<br />Used for Fuel<br />To make highways and roads<br />For Agriculture<br />Urban and Construction <br />Clearing forests for oil and mining exploitation;<br />Wildfires<br />Acid rain<br />
  • 13. What are the Effects of Deforestation?<br />
  • 14. What are the Effects of Deforestation?<br />Erosion of Soil<br />Disruption of the Water Cycle <br />Loss of Biodiversity <br />of Soil<br />Climate Change<br />Flooding and Drought<br />
  • 15. Deforestation in the World<br />
  • 16. Deforestation in the Brazil<br />Rondonia, Brazil<br />
  • 17. Deforestation and Global Warming<br />
  • 18. Deforestation and Global Warming<br />20% of global warming is caused by deforestation<br />
  • 19. Thankyou!<br />
