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.

项目总结/摘要 受野火影响的社区的低成本安培臭氧监测器 野火（森林火灾、生物质燃料火灾等）的频率和严重程度不断上升。在美国， 重要的环境公共卫生问题。野火产生的烟雾顺着风飘得很远， 大约三分之二的美国人接触到对环境空气质量有害的污染物。绝大多数的医学和 科学工作的重点是人们对这些火灾产生的细颗粒物的接触。 然而，野火产生的臭氧会导致许多肺部健康状况，与颗粒物不同， 无法使用HEPA过滤器或N95口罩缓解。尽管有负面的健康影响， 可用于监测这些自然灾害期间的环境臭氧浓度。电流检测 设备昂贵、易受干扰，并且在便携时牺牲了准确性。因此，委员会认为， 大多数社区几乎没有关于他们接触的信息，卫生官员无法评估他们的健康状况。 野火产生的臭氧对健康的影响。 电化学气体传感器技术的最新进展使其成为一种有吸引力的监测选择 环境空气污染物。丝网印刷电极的制备及非水电解研究进展 电解质已经产生了具有与台式仪器相当的性能的低成本装置。兴趣 在室温下，离子液体（RTILs）作为替代电解质介质，已取得了长期的远程气体 感知更实用。与水性电解质不同，RTIL具有可忽略的蒸气压和高稳定性 因此它们不会变干或参与电化学反应。这个程序会冲洗出一层厚膜 使用RTIL的电化学传感器，用于受影响社区的臭氧自主监测 野火利用Giner的电化学传感器经验，将广泛生产低成本臭氧检测器 首次向公众开放。Giner完全开发的监测仪的检测限（LOD）为 10 ppb，线性范围10-500 ppb，并防止其他常见野火气体的干扰。一 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 供受影响社区的卫生官员、研究人员和公民使用。
