  • 1. Air Pollution Ekaterina Shaleva Stoyan Kolev 10/8
  • 2. What is Air Pollution?
    • The presence of chemicals in the atmosphere, which are not a normal part of it [1]
    • In other words, it is contaminated air [1]
    • The main sources of air pollution are ground-level ozone, particulate matter (PM), nitrogen and sulphur oxides [5]

  • 3. What is ground-level ozone?
    • Ozone(O3) is a gas, which forms a layer that protects the Earth from ultraviolet rays [5]
    • When ground level is created, it becomes a major air pollutant [2]
    • Sources - not emitted directly into the air; [2]
    • Health Effects- coughing, irritation of the airways, discomfort when breathing, premature aging of the lungs, increased risk of respiratory infections [2]
    • Environmental Effects- on plants and ecosystems- damaging leaves, reducing forest growth and crop yields, making plants more susceptible to certain diseases [5]
    • Economic Effects- tourism suffers, increased cost for health care services [3]
    http://www.greenfacts.org/en/ozone-o3/index.htm#3
  • 4. What is particulate matter?
    • The sum of all liquid and solid particles in the air [5]
    • PM10- big coarse particles (up to 10 micrometers in size), cause less severe health problems [4]
    • PM2.5-small fine particles (up to 2.5 micrometers in size), worse health effects [4]
    • Sources - any activity which involves burning of materials-forest fires, crushing and grinding rocks, processing metals [5]
    • Health Effects- coughing, wheezing, aggravated asthma, lung damage [4]
    • Environmental Effects- decreases visibility, harms crops and plants [5]

  • 5. What are Nitrogen Oxides?
    • Group of gases composed of nitrogen and oxygen [6]
    • Most common are nitric oxide and nitrogen dioxide, which is a greenhouse gas [6]
    • Sources - motor vehicle exhaust, burning of coal, cigarette smoking, etc. [6]
    • Health Effects- headache, fatigue, dizziness, difficult breathing, throat spasms, collapse, death [6]
    • Environmental Effects- NO2 helps form acid rain, contributes to global warming, hampers the growth of plants, with VOC forms ground- level ozone [7]
  • 6. What are sulphur oxides?
    • Most common is sulphur dioxide, which together with NO2 is one of the main chemicals that cause acid rain [8]
    • Sources- mostly from power station and oil refineries, but also from volcanoes, forest fires [8]
    • Health Effects- respiratory problems, aggravation of existing cardiovascular diseases [9]
    • Environmental Effects –damage crops, forests, acidify soils and water bodies [8]

  • 7. Bulgaria’s Air Quality
    • Bulgaria has the most polluted air in the European Union [10]
    • Main pollutants- industrial development, deforestation, large number of old vehicles, coal-fired heating in smaller towns [10][11]
    • Sofia and Plovdiv experience the worst air pollution as well as the town of Pernik, which has pollution twice the permitted level (high number of metallurgy plants) [10][12]
    • Actions- member of various international environmental agreements- Air Pollution- Sulfur 85, Antarctic Treaty, Ozone Layer Protection, etc; imposes EU standards on vehicles and industry [10][11]

  • 8. Ex ample #1: Norilsk, Russia
    • World’s largest smelting complex for heavy metals causes extreme air pollution in a 60 km radius [ 13]
    • Metals in the air: nickel 500 tons per year , copper 500 tons per year , cobalt, lead, selenium [13]
    • Other gasses: sulfur dioxide 2 million tons per year, phenols, hydrogen sulfide [13]

  • 9.
    • Effects on people:
    • -Life expectancy- 10 years smaller than anywhere in Russia;
    • -respiratory diseases; ear, nose, throat diseases;
    • -pregnancy and birth problems;
    • -lung cancer due to sulfur dioxide;
    • -responsible for about 20 percent of adult mortality and about 30 percent of adolescent mortality [13]
    • Solution:
    • Norilsk Nickel ahs spent $5mil Overhauling of dust & gas recovery & removal systems and plans to decrease sulfur dioxide emissions by 500% until 2015 [13]
  • 10. Example #2: London, England
    • Issue: Traffic, Factories produce PM10s [15]
    • Air Pollution: PM10s (particles smaller than 10 microns) [14]

  • 11.
    • Effects on people:
    • -PM10s- small enough to be inhaled in the deepest parts of the lungs, main cause for lung diseases and heart attacks [14]
    • -accounted for the death of 3000 Londoners annually [15]
    • Solution:
    • Boris Johnson, London mayor is in the process of issuing a ban on all taxis over 10 years old, which will probably reduce the crisis by half [15]
