Chapter Overview
Chapter 13: Environmental Chemistry-Air focuses on the chemistry of the earth's atmosphere and the human impact on it. It begins with the structure of the atmosphere (layers like troposphere, stratosphere, mesosphere, thermosphere), the nature of air pollutants, and the chemical reactions involved in smog (photochemical vs. industrial) and acid rain.
Air quality parameters are discussed in detail, highlighting Air Quality Index (AQI) criteria, Particulate Matter (PM2.5 and PM10) monitoring, gaseous pollutants detection, remote sensing, and health impact assessments. It also covers international clean air regulations, emission standards, trading schemes, vehicle emission testings, and clean energy initiatives.
Finally, the chapter details the greenhouse effect and global warming, describing the greenhouse gases, causes, and consequences of global warming. It reviews the economic, social, and political issues surrounding air pollution, alongside experimental techniques to measure particular matter and gaseous pollutants like carbon monoxide.
