, Volume 2 presents a critical review of the sampling, characterization, and behavior of particles in air, surface and ground water, sediments, and solids. The book analyzes the formation, aggregation, transport, and conversion of particles, and it evaluates the capabilities of physical and chemical methods of analysis. It also discusses physicochemical properties of environmental particles, their spectroscopic characterization and colloid chemical properties, and how they affect biochemical and/or toxicological processes. The book will be an important reference for environmental chemists and physicists, limnologists, oceanographers, air and soil scientists, analytical chemists, environmental engineers, and students.
