Abstract: Detecting nanomaterials in the environment is a demanding task, not only because of the extremely small size of the particles and their potential sequestration and agglomeration, but also because of their unique physical and chemical characteristics. The aim of this review is to recommend a way forward on tackling the challenge of engineered nanomaterial detection in the environment. An overview will be presented of the available analytical techniques used for the detection and characterization of nanoparticles in environmental matrices including particle-size analysis, particle-fraction concentration counts, surface-area analysis, morphology, and particle chemical composition analysis. Sample preparation aspects, imaging techniques (electron microscopy, scanning electron microscopy, or X-ray microscopy), separation methods (e.g. flow field fractionation, electrophoresis, liquid chromatography, hydrodynamic chromatography), and detection/characterization techniques (e.g. light scattering, inductive coupled plasma, mass spectrometry) have been included. This review also introduces what is known concerning their fate, behavior, disposition, and toxicity.
