The purpose of the IUPAC Series on Analytical and Physical Chemistry of Environmental Systems is to make chemists, biologists, physicists and other scientists aware of the most important biophysicochemical conditions and processes that define the behaviour of environmental systems. The various volumes of the set emphasize the fundamental concepts of environmental processes, taking into account specific aspects such as physical and chemical heterogeneity, and interaction with the biota. The volumes discuss the analytical tools that are available, or should be developed, to study these processes.Titles in this SetEnvironmental Colloids and Particles - Behaviour, Separation and CharacterisationThe Biogeochemistry of Iron in SeawaterPhysicochemical Kinetics and Transport at BiointerfacesInteractions Between Soil Particles & Microorganisms - Impact on the Terrestrial EcosystemAtmospheric ParticlesIn Situ Monitoring of Aquatic Systems – Chemical Analysis & Speciation
