1134231 Brant这项由环境、健康和安全纳米技术计划授予的NSF奖项支持Jonathan Brant教授研究从饮用水中去除人造纳米材料的工作。项目组还将研究将饮用水处理过程中产生的残留废物中的人造纳米材料释放到自然环境中。这项工作对普通公众很重要，因为它将提供必要的数据，以确定使用传统和先进技术处理过的饮用水中各种人造纳米材料的预期剂量。它还将有助于确定现有处理残留物处理方法的适宜性，以防止人造纳米材料释放到周围环境。为了确定可能与人造纳米材料的持续开发和商业化有关的风险，以及最终与纳米技术进步所产生的产品有关的风险，需要这些信息。首先，从这项工作中获得的结果和见解将为工程师、科学家和监管机构开始评估现有处理方案有效地从饮用水中去除人造纳米材料的能力提供基础。此外，它还将对这些物质的浓度或剂量进行定量评估，这些物质可能合理地出现在经过常规处理的饮用水中。这些发现对社会具有重大意义，因为它试图了解与纳米技术相关的风险，而制造的纳米材料与纳米技术密切相关。其次，怀俄明州的学生，无论是K-12年级的学生还是大学水平的学生，都将学习如何使用传统和先进的方法处理饮用水，并将被介绍给明天的一个？S，最紧迫的问题？新的饮用水污染物的出现和随后的清除。

1134231BrantThis NSF award by the Environmental Health and Safety of Nanotechnology program supports work by Professor Jonathan Brant to study the removal of manufactured nanomaterials from drinking water. The project team will also study the release of manufactured nanomaterials into the natural environment from the residual waste products that are generated during the drinking water treatment. This work is important to the general public because it will provide the data that is necessary for determining what dose may be expected for various manufactured nanomaterials in drinking water that has been treated using conventional and advanced technologies. It will also help to determine the suitability of existing approaches for disposing of treatment residuals for preventing the release of manufactured nanomaterials into the surrounding environment. Such information is needed in order to determine the risk that may be associated with the continued development and commercialization of manufactured nanomaterials, and ultimately with the products that result from advancements in nanotechnology.The broader significance and importance of this project will be twofold. First, the results and insights gained from this work will provide a basis by which engineers, scientists, and regulators can begin to assess the ability of existing treatment schemes for effectively removing manufactured nanomaterials from drinking water. Furthermore, it will provide a quantitative assessment of the concentration, or dose, of these materials that may reasonably be expected to occur in conventionally treated drinking water. These findings hold great significance for society as it seeks to understand the risks that are associated with nanotechnology, with which manufactured nanomaterials are intimately related. Second, students in Wyoming, both K-12 and college level, will learn how to treat drinking water using both conventional and advanced approaches and be introduced to one of tomorrow?s most pressing problems ? the emergence and subsequent removal of new drinking water contaminants.
