Document Summary

Lecture 12: air pollution, waste management & land use. The earth system cycles water, air and soil from a chemical and physical perspective. When we insert pollutants into the atmp it enters these cycles and has a domino affect. Pollutants and particulates in the atmosphere get into the water and soil cycles. Air pollution: serious health hazard in many large cities. Effects on human artifacts: effects of air pollution on buildings and monuments: acid rain can dissolve away statues and impact many aspects. Aesthetic effects: reducing visual range and atmospheric clarity. Physical state (air pollutants can be in any state: gaseous form: so2, nox, co, o3, organic compounds, solid or liquid particulates. Air toxins: pollutants causing cancer or other serious health problems. Map: deaths attributed to ambient air pollution, 2012: some areas are much worse than others, and this is a serious health issue. An estimated 4. 2 million premature deaths globally are linked to ambient air pollution annually.
