Class 13b: Air pollution Particulate matter Acid rain Photochemical smog Ozone and the ozone layer
Air pollution Pollution: concentration of substances that harms living things Ash, smoke, dust, pollen Fossil fuels, solvents 3 million deaths worldwide
Air pollution Physical geography –Prevailing windswinds –Topography and inversions Level of urbanization, industrialization Particulate matter or chemical compounds
Particulate matter Source: incomplete burning of fuel Respiratory problems Short transport distance Closest to source = most affected
Acid rain Source: burning fossil fuels Sulfur from coal becomes sulfuric acid Terrestrial effects (forests, soils) Aquatic effects Material effects (buildings, monuments)
Photochemial smog Sources: incomplete burning of fuel Nitrogen dioxide, hydrocarbons, and sunlight Forms ozone at ground level Respiratory problems, damage to plants
Ozone layer Ozone is necessary at high altitude Absorbs UV (ultraviolet) radiation CFCs, other chemicals break down ozone One of few international success stories
Air Pollution. Whats in the Air? Nitrogen, oxygen, carbon dioxide, water vapor, and other gases Air pollution –Solid particles and gases that are released.
