IAP conferences seek to provide a forum for researchers working in the interdisciplinary field of Environmental Science, the main focus of their work being the importance of (bio) colloids and (bio) interfaces in natural reactive processes, both from fundamental and applied perspectives. The scope includes topics of societal concern such as environmental protection, (bio) remediation of polluted sites, optimisation of mineral resources, impacts of nanotechnology residues on the environment, and the key role played by interfaces in governing the fate and behavior of pollutants in the environment. An adequate investigation of these matters necessarily requires joint experimental and theoretical expertise from physicists, physical chemists, biologists and geoscientists,
