The benefits of nanomaterials and their enabling properties have resulted in widespread use in industry and consumer products. As we approach 20 years of research on the potential impacts of nanomaterials on human health and the environment, differences remain in the scientific and regulatory communities regarding whether nanomaterials need to be assessed differently and more stringently than conventional materials. There is however a growing consensus that nanomaterials exhibit complex and interesting interactions with organisms and ecosystems. There is also visible convergence regarding methods of evaluation and assessments where nanotechnology is likely to yield greater environmental benefits or risks. This conference will take stock of what has been learned, point the scientific community towards specific conclusions, discuss needs for data integration, and finally identify remaining research gaps. The overall goal of the conference will be to integrate the scientific knowledge available about nanomaterial exposure, fate, effects and risks in the environment. The conference will bring together experts from around the world to discuss the state of the science on nanomaterials, their impacts, and their applications, with a dedicated discussion of applications and implications at the nano-bio interface. Specific scientific objectives of the conference will be: - Discuss environmental exposure of nanomaterials including their release from products and their detection - Summarize known transport and transformation pathways of nanomaterials - Discuss recent findings on uptake and effects in organisms and food-chains - Present the progress towards environmental risk assessment of nanomaterials - Identify nano-specific issues in exposure, fate, effects and risks - Discuss the relevance of nanomaterials compared to natural particles The main results obtained from addressing the above objectives will be summarized in a synthesis paper, which concludes on the topic of whether nanomaterials pose a novel threat under environmentally relevant conditions.

纳米材料的益处及其赋能特性已导致其在工业和消费品中的广泛使用。随着我们对纳米材料对人类健康和环境的潜在影响进行了近20年的研究，科学界和监管界在是否需要对纳米材料进行不同于传统材料的更严格的评估方面仍然存在分歧。然而，越来越多的人一致认为，纳米材料与生物体和生态系统之间存在复杂而有趣的相互作用。在纳米技术可能产生更大的环境效益或风险的评价和评估方法方面也有明显的趋同。本次会议将总结所学到的知识，为科学界指出具体的结论，讨论数据整合的需求，并最终确定剩余的研究差距。会议的总体目标是整合有关纳米材料暴露、归宿、影响和环境风险的现有科学知识。会议将汇集来自世界各地的专家，讨论纳米材料的科学状况，其影响及其应用，并专门讨论纳米生物界面的应用和影响。会议的具体科学目标是：- 讨论纳米材料的环境暴露，包括其从产品中的释放及其检测-总结已知的纳米材料的运输和转化途径-讨论生物体和食物链中吸收和影响的最新研究结果-介绍纳米材料环境风险评估的进展-确定暴露、归宿、影响和风险-讨论纳米材料与自然颗粒相比的相关性将在一份综合文件中概述从实现上述目标中获得的主要结果，该文件最后将讨论纳米材料在环境相关条件下是否构成新的威胁这一主题。
