  2. Introduction • Air pollution • Ecosystems • Interaction • Regulation & policy • Reality

  3. Air Pollution • Factors that make air pollution a concern • Types • Emission sources • Transport • Deposition

  4. Air Pollution (cont.) • Common pollutants of concern • Nitrogen • Sulfur • Mercury • Particulates • Carbon • Ozone • Secondary pollutants

  5. Ecosystems • Functioning units of nature • Plants • Animals • Micro-organisms • Non-biological components • Climate and weather • Complex interaction

  6. Ecosystems (cont.) • Physical & biological relationship • Cyclic • Spatial boundaries • Identifiable • Various political classifications • Fundamental sustenance • Supports life

  7. Interaction • Various scales • Local to continental • Sources • Natural and human-made • Receptors • Air, land, water, plants, lungs….

  8. Interaction • Weather • Temperature driven • Climate • Weather over time • Exposure • Dose • Effect
