项目摘要

PROJECT SUMMARY/ABSTRACT Low-Cost Amperometric Ozone Monitor for Communities Affected by Wildfires The rising frequency and severity of wildfires (forest fires, biomass fuel fires, etc.) in the United States is an important environmental public health issue. Smoke produced during a wildfire travels far downwind, exposing roughly 2/3 of Americans to pollutants detrimental to ambient air quality. A vast majority of the medical and scientific effort is focused on the populations’ exposure to fine particulate matter produced during these fires. However, ozone from wildfires can lead to many pulmonary health conditions and, unlike particulate matter, cannot be mitigated using HEPA filters or N95 masks. Despite the negative health effects there are few tools available for monitoring ambient ozone concentrations during these natural disasters. Current detection equipment is expensive, prone to interference, and sacrifices accuracy when made portable. Consequently, most communities have little information regarding their exposure and health officials are unable to assess the health impact of ozone produced from wildfires. Recent advancements in electrochemical gas sensor technology make them an appealing option to monitor ambient air pollutants. Developments in screen printed electrode fabrication and research into non-aqueous electrolytes have resulted in low-cost devices with performance comparable to bench top instruments. Interest in room temperature ionic liquids (RTILs) as an alternative electrolyte media has made long-term remote gas sensing more practical. Unlike aqueous electrolytes, RTILs have negligible vapor pressures and high stability so they do not dry out or take part in electrochemical reactions. This program will develop a thick-film electrochemical sensor utilizing RTILs for autonomous monitoring of ozone in communities affected by wildfires. Leveraging Giner’s electrochemical sensor experience a low-cost ozone detector will be made widely accessible to the public for the first time. Giner’s fully developed monitor will have a limit of detection (LOD) of 10 ppb, linear range of 10-500 ppb, and prevent interference from other common wildfire gases. A corresponding portable instrument will be developed to include electronics, battery power, and wireless data communication for use by health officials, researchers, and citizens within affected communities.

项目摘要/摘要针对受野火影响的社区的低成本安培臭氧监测器在美国，野火的频率和严重程度上升（森林火灾，生物质燃料大火等）是重要的环境公共卫生问题。在野火期间产生的烟雾远方游动，暴露大约有2/3的美国人对污染物有害于环境空气质量。绝大多数医疗和科学努力集中在人群对这些火灾中产生的细微物质的暴露。但是，来自野火的臭氧会导致许多肺部健康状况，与特定物质不同，无法使用HEPA过滤器或N95口罩来缓解。尽管有负面影响，但工具很少可用于监测这些自然灾害期间的环境臭氧浓度。当前检测设备很昂贵，容易干扰，并在使便携式时牺牲精度。最后，大多数社区几乎没有有关其暴露的信息，卫生官员无法评估野火产生的臭氧的健康影响。电化学气体传感器技术的最新进展使它们成为监视的吸引人的选择环境空气污染物。丝网印刷电极制造中的开发和非水的研究电解质产生了低成本设备，性能与台式仪器相当。兴趣在室温下，离子液体（RTILS）作为替代电解质介质已成为长期远程气体感觉更实用。与水解物不同，RTIL具有微不足道的蒸气压力和高稳定性因此，它们不会干燥或参与电化学反应。该程序将发展一个厚实的电影电化学传感器使用RTIL进行自动监测臭氧的社区中的臭氧野火。利用Giner的电化学传感器体验，低成本的臭氧检测器将被广泛制造公众可以首次访问。 Giner完全开发的监视器将具有检测限（LOD） 10 ppb，线性范围为10-500 ppb，并防止其他常见野火气体干扰。一个将开发相应的便携式仪器，包括电子设备，电池电源和无线数据卫生官员，研究人员和受影响社区内的公民使用的通信。
