  • Air pollution

    1. 1. Human Impact on our Ecosystem Air Pollution Siyana Julia Boris
    2. 2. The Problem of Air Pollution <ul><li>Very old but much worse in modern times due to: </li></ul><ul><ul><li>Industrial development </li></ul></ul><ul><ul><li>Motor cars </li></ul></ul><ul><ul><li>Demographic boom </li></ul></ul><ul><ul><li>Neglect of the environment </li></ul></ul><ul><ul><li>(1) </li></ul></ul>
    3. 3. Causes and Effects of Air Pollution
    4. 4. Sources of Pollutants <ul><li>Transportation (mainly automobiles) </li></ul><ul><ul><li>Carbon monoxide (CO) </li></ul></ul><ul><ul><li>Hydrocarbons (HC) </li></ul></ul><ul><ul><li>Nitrogen oxides (NOx) </li></ul></ul><ul><li>Power plants and other industrial facilities </li></ul><ul><li>Fuel combustion in stationary sources </li></ul><ul><ul><li>Sulfur dioxide (SO 2 ) </li></ul></ul><ul><li>(1) </li></ul>
    5. 5. Types of Pollutants <ul><li>Carbon dioxide </li></ul><ul><li>NOx – nitrogen oxide (NO), nitrogen dioxide (NO2), nitrous oxide (N2O) </li></ul><ul><li>Sulfur and chlorofluorocarbons (CFC or freons) </li></ul><ul><li>Particulate matter </li></ul><ul><li>Smog </li></ul><ul><li>(1) </li></ul>

    7. 7. Specific Factors for Air Pollution in Bulgaria <ul><li>Large share of old vehicles without catalytic converters </li></ul><ul><li>Lack of restrictions on imported second hand cars </li></ul><ul><li>Heating – still a lot of coal burning in the countryside </li></ul><ul><li>Metallurgy – steel production, non-ferrous metals </li></ul><ul><li>(1) </li></ul>
