This note provides a detailed overview of the chemical
transformations that control the abundances of key trace species in the Earth's
atmosphere. This note covers the following topics: photochemistry, kinetics, and
thermodynamics important to the chemistry of the atmosphere, stratospheric ozone
depletion, oxidation chemistry of the troposphere, photochemical smog, aerosol
chemistry, and sources and sinks of greenhouse gases and other climate forcers.
This lecture note
covers most of the core aspects of environmental science, focusing on pollution
and waste management: air pollution, water pollution, and treatment and methods
of water treatment both as a theoretical background and real-life insights. This
includes oil contamination in both freshwater and marine waters, where a
discussion of effects and how to treat oil spills comes into play. A section on
Hazardous Waste discusses sources, disposal methods, and impact on the
environment. That's helpful for a student or environmental scientist interested
in discussing pollution problems but also possible solutions.
This
lecture note is an introduction to key environmental chemistry topics. It begins
with the composition of the atmosphere and pollutants responsible for
environmental degradation. The topics discussed include the Chapman cycle,
protection of the ozone layer, and the seasonal depletion of ozone in
Antarctica. Principles of combustion, alternative fuels, and the role of water
in environmental sustainability are also covered in it. This occupies a good
part of the note-writing; acid rain, and its impact on the environment. It is
basically important reading to those students who wish to link chemistry with
environmental protection.
