Iron ranks the second most abundant metal element in the Earth’s Crust and is ubiquitous in atmospheric aerosols, natural waters and soils as well as animals and plants. Iron could play an important role in the processes of the biogeochemical cycling in the environment and chemical dynamics in organisms because of its abundant existence and redox properties. Iron cycling and its coupling interactions can directly drive the geochemical cycling of some major and trace elements, such as carbon, nitrogen and sulfur, and have strong influence on the fate, transport, transformation and bioavailability of natural contaminants. Iron cycling has great significant characteristics, such as the important spatial location, functional diversity and strategic position. Thus, iron cycling and its corresponding environmental implications are the core of iron environmental chemistry research, and have become the internationally cutting-edge topic and recognized as the key scientific issue to uncover the geochemical cycling processes in the Critical Zone. The iron environmental chemistry research involves multidisciplinary cross connection, and is geared to national great demands, thus can realize the removal of multimedia pollutants. The research achievements of iron environmental chemistry and its related pollutant control technology will serve for the three Environmental Defense Wars of water, soil and air.
