摘　　要：石墨烯是当前研究最热的碳纳米材料,具有独特的理化特性,在各领域广泛应用。随着石墨烯生产和使用量的不断增大,其不可避免地进入到环境中,给生态环境和人类健康带来风险。阐明石墨烯的潜在毒性效应及其作用机制对于客观评价石墨烯的生态环境健康风险具有重要意义。迄今为止,已有诸多研究报道了石墨烯的植物生理毒理效应。研究表明,石墨烯对植物的生理学响应及其生理变化过程存在影响,涉及萌芽、幼苗生长、氧化应激、光合特性、植物激素和代谢过程等,且多呈浓度效应。今后亟需构建一套被广泛认可的植物石墨烯毒性评价体系,为石墨烯的安全生产和使用提供指导。Graphene is one of the most popular carbon nanomaterials that widely used in many fields due to its unique physical and chemical properties.The expanding production and application of graphene materials has led to their inputs into the environment,with increasing risks of environment and human health.Therefore,elucidating the potential toxic effects of graphene and the related mechanism are of significance to evaluate its ecological risk and bio-safety.To date,many studies have reported the physiotoxicological effects of graphene on plants.Literature showed that graphene had concentration-dependent effects on the physiological response of plants,including seed germination,growth,oxidative stress,photosynthetic characteristics,plant hormones,and metabolic processes.In the future,it is necessary to establish a widely accepted phytotoxicity evaluation system for the safe manufacture and use of graphene.
