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.
碳纳米材料是多种应用的理想候选材料，因此，它们的研究是近年来的一个热点。碳纳米材料的大量生产和使用将不可避免地导致这些材料释放到环境中，并可能引发潜在的环境和生态风险。一方面，碳纳米材料本身对生物体有毒；另一方面，它们对环境中的污染物具有更强的吸附能力，从而影响污染物的迁移和归宿。目前，关于碳纳米材料生态风险的研究主要集中在其潜在的生物毒性上，而关于其环境行为及其对环境中污染物迁移和归宿影响的研究较少。本文综述了碳纳米材料的来源、暴露途径、环境行为及其对环境中污染物迁移和归宿的潜在影响。讨论了纳米材料环境和生态风险评估研究的意义。
