CAREER: New Methods for the Direct Quantification of Air Pollutant Emissions and Education of the Next Generation of Engineers

马尔0547107的智力成就。该项目的学术价值在于，它将为空气污染物排放的量化提供一个新的工具，它是首次直接测量氮氧化物、挥发性有机化合物和细颗粒物进入大气的人为通量，并将显著增强对空气污染物排放的了解。与目前依赖工程估算来预测排放量的方法相比，这种方法是一个重大进步。这些测量将为空气质量科学和管理的进步提供显著改善的数据。最终，这项研究将通过科学和教育带来更有效的空气质量控制策略和更清洁的空气。新的空气质量法规预计将每年花费超过65亿美元，并可能节省1200亿美元的健康相关费用。准确的排放测量将确保减少空气污染的努力从成本效益上得到优化。综合教育组成部分项目将至少产生两个重大影响。首先，向K-12学生介绍我们的现场测量将激发他们对科学和工程的兴趣，并将鼓励更多的学生进入技术领域学习。其次，通过新的无线课堂技术和主动学习技术的结合，本科生将对环境工程有更深入的了解，并更有可能在整个职业生涯中保留这些知识。这项技术可能尤其有助于少数族裔和女性学生克服文化、性别和社会障碍，这些障碍阻碍了他们更积极地参与传统教学的课程。更多受过更好教育的科学家和工程师将提高我们在未来几十年成功应对空气污染和其他环境挑战的能力。

Marr 0547107 Intellectual merit. The intellectual merits of this project are that it will provide a new tool for the quantification of air pollutant emissions, that it represents the first direct measurement of anthropogenic fluxes of nitrogen oxides, volatile organic compounds, and fine particulate matter to the atmosphere, and that it will significantly enhance understanding of air pollutant emissions. This method is a significant advance over the current approach, which relies on engineering estimates to predict emissions. These measurements will provide significantly improved data for the advancement of air quality science and management.Broader impacts. Ultimately, this research will lead to more effective air quality control strategies and cleaner air through both science and education. New air quality regulations are expected to cost over $6.5 billion per year and potentially save $120 billion in health-related expenses. Accurate measurements of emissions will ensure that efforts to reduce air pollution are optimized for cost effectiveness. The projects integrated educational components will have at least two significant impacts. First, introducing K-12 students to our field measurements will excite them about science and engineering and will encourage more of them to enter technical fields of study. Second, through the combination of new wireless classroom technology and active learning techniques, undergraduate students will gain a deeper understanding of environmental engineering and will be more likely to retain the knowledge throughout their careers. This technology may especially aid minority and female students to overcome cultural, gender, and social barriers that inhibit them from participating more actively in traditionally taught classes. A larger pool of better educated scientists and engineers will improve our ability to successfully tackle air pollution and other environmental challenges in the coming decades.
