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.

项目概要/摘要适用于受野火影响社区的低成本安培臭氧监测仪美国山火（森林火灾、生物质燃料火灾等）的频率和严重程度不断上升，是一个严重的问题。野火期间产生的烟雾沿着风向传播很远，暴露了重要的环境公共卫生问题。大约 2/3 的美国人对环境空气质量的污染物感到痛苦，绝大多数是医疗和健康问题。科学研究的重点是人们接触这些火灾期间产生的细颗粒物的情况。然而，野火产生的臭氧会导致许多肺部健康问题，并且与颗粒物不同，尽管对健康有负面影响，但使用 HEPA 过滤器或 N95 口罩无法缓解。可用于监测这些自然灾害期间的环境臭氧浓度。设备价格昂贵，容易受到干扰，并且在便携式测试时会牺牲精度。大多数社区几乎没有关于其接触情况的信息，卫生官员也无法评估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的丝网印刷电极制造和非水研究的进展。电解质已产生性能可与台式仪器相媲美的低成本设备。室温离子液体（RTIL）作为替代电解质介质已使长期远程气体与水性电解质不同，RTIL 的蒸气压可以忽略不计，并且稳定性较高。因此它们不会干燥或参与电化学反应。该程序将形成厚膜。利用 RTIL 的电化学传感器对受气候影响的社区中的臭氧进行自主监测利用 Giner 的电化学传感器经验，将广泛制造低成本的臭氧检测器。 Giner 完全开发的监视器首次向公众开放，其检测限 (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。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内的卫生官员、研究人员和公民使用的通信。
