Global Warming Seminar: Acid Rain & Deforestation
1. acid rain anddeforestation | causes, effects and impacts Luis Paulo Carneiro & Ricardo Coqueiro Wizard University #seminar 01| Sao Paolo, August, 26th-10
2. Acid rain By Luiz Paulo CARNEIRO ChemicalEngineer, specializing in Environmental
3. How Acid RainWorks Acid rain occurs mostly in the Northern Hemisphere 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. SO2 / NOx + H2O-> H2SO4 / HNO3
4. The pH of Acid Rain Express the acidity of acid rain using the pH scale. The scale defines a solution's acidity, neutrality or alkalinity based on its concentration of hydrogen ions. ( 0 – 14 pH) Acids – pH > 7,0 Most life is comfortable at a near- neutral pH (7,0
5. The pH of Acid Rain Acidrain - pH of 5.0 orless. Mostaciddeposition ranges from pH 4.3 to 5.0
7. The Effects of Acid Rain Ex: Oldbuildings, monumentstombstones, automotivepaint
8. The Effects of Acid Rain Effects for our health Sulfate (SO4), nitrate (NO3) particulates of dry deposition can cause asthma, bronchitis and heart problems. 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.
10. What is Deforestation? Is a process of cutting trees to make spaces frees for pastures, industries, households of the ever-increasing human population;
12. What are the Causes of Deforestation? To Create Grazing Land Used for Fuel To make highways and roads For Agriculture Urban and Construction Clearing forests for oil and mining exploitation; Wildfires Acid rain
14. What are the Effects of Deforestation? Erosion of Soil Disruption of the Water Cycle Loss of Biodiversity of Soil Climate Change Flooding and Drought
