[Carbon nanomaterials: their environmental behavior and effects on the transport and fate of pollutants in environment].

Carbon nanomaterials are the excellent candidates br a variety of applications, and tnus, their research is a hotspot in recent years. The big amount production and utilization of carbon nanomaterials will inevitably lead to the release of these materials into environment, and may incur potential environmental and ecological risks. On the one hand, carbon nanomaterials themselves are toxic to living organisms; on the other hand, they have stronger adsorbing capability on the pollutants in environment, and thus, affect the transport and fate of the pollutants. At present, the researches on the ecological risk of carbon nanomaterials are largely focused on their potential bio-toxicity, while a few are on their environmental behavior and their effects on the transport and fate of pollutants in the environment. This paper reviewed the researches on the sources, exposure pathways, and environmental behavior of carbon nanomaterials, and their potential effects on the transport and fate of pollutants in the environment. The significances of the research on the assessment of environmental and ecological risks of nanomaterials were discussed.
