Introduction to Environmental Chemistry

This lecture covers the basics of environmental chemistry, including the chemistry of natural aquatic systems, fate of organic contaminants, and its relation to environmental engineering. It delves into the sources, reactions, transport, effects, and fates of chemical species in water, soil, and air environments, emphasizing the importance of understanding the chemistry of natural systems. Various concepts such as pH influences, speciation, and the composition of natural waters are discussed, along with the impact of anthropogenic contaminants like DDT. The lecture also explores acid-base reactions, redox reactions, and dissolution/precipitation equilibria in environmental systems.
