Phohemical reactions play a major role in the environment including a wide range of reactions in the atmosphere, natural waters, soil and living organisms. This new volume on Environmental Phohemistry up-dates the previous edition with chapters on basic aspects including concepts of phohemical transformations and mechanistic phohemical processes in the atmosphere and water. In addition a range of applications are also detailed such as advanced phohemical oxidation processes for water and air treatment as well as applications of phoatalysis for surface treatment and nuclear fuel reprocessing. The new edition provides a critical up to date overview of the most important research in the field of environmental phohemistry.
