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.

1134231 Brant这个由纳米技术计划的环境健康和安全NSF奖支持乔纳森·布兰特教授研究从饮用水中去除人造纳米材料的工作。项目小组还将研究饮用水处理过程中产生的残留废物中人造纳米材料向自然环境的释放情况。这项工作对公众很重要，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。它还将有助于确定处理残留物的现有处置方法是否适合防止人造纳米材料释放到周围环境中。为了确定人造纳米材料的持续开发和商业化以及最终与纳米技术进步所产生的产品有关的风险，需要此类信息。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从饮用水中有效去除人造纳米材料的能力提供基础。此外，它将提供这些材料的浓度或剂量的定量评估，这些材料可能合理地预期会出现在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，人造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还是大学水平，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学生？最紧迫的问题是什么？新的饮用水污染物的出现和随后的去除。
