美国环境保护署（EPA）和其他联邦机构在解释和协调移动和手持空气传感器的短时间（秒到分钟）读数与与国家环境空气质量标准（NAAQS）相关的较长时间平均值（小时到天）方面面临着许多挑战，这些标准污染物包括颗粒物（PM）、臭氧、一氧化碳、铅、氮氧化物和硫氧化物。类似的问题同样适用于有害空气污染物，其中特定化学品的健康影响参考值是接触限值的最佳指标；这些值通常是基于持续暴露的生命周期。2013年召开了一个多机构、工作人员级别的空气传感器健康小组。ASHG代表了联邦机构的多机构合作，致力于发现和讨论传感器技术，解释传感器数据，定义每个机构的传感器相关科学状态，并就如何有效地使用传感器来满足广泛的研究和决策支持需求提供咨询。ASHG侧重于几个方面：提高对手持传感器技术可能提供的内容的理解；向众多受众传达手持传感器读数所能提供的信息；如何使用新的和未经验证的技术整合多个实体产生的数据的挑战；确定向不同受众传达健康相关信息的最佳做法。这篇综述总结了ASHG最初努力的挑战、成功和有前途的工具，以及联邦机构在制作用于其他NAAQS污染物和HAPs的类似产品方面的进展。注：本文仅代表作者个人观点，并不代表其所属联邦机构或美国政府的观点。提及产品名称不构成背书。
The US Environmental Protection Agency (EPA) and other federal agencies face a number of challenges in interpreting and reconciling short-duration (seconds to minutes) readings from mobile and handheld air sensors with the longer duration averages (hours to days) associated with the National Ambient Air Quality Standards (NAAQS) for the criteria pollutants-particulate matter (PM), ozone, carbon monoxide, lead, nitrogen oxides, and sulfur oxides. Similar issues are equally relevant to the hazardous air pollutants (HAPs) where chemical-specific health effect reference values are the best indicators of exposure limits; values which are often based on a lifetime of continuous exposure. A multi-agency, staff-level Air Sensors Health Group (ASHG) was convened in 2013. ASHG represents a multi-institutional collaboration of Federal agencies devoted to discovery and discussion of sensor technologies, interpretation of sensor data, defining the state of sensor-related science across each institution, and provides consultation on how sensors might effectively be used to meet a wide range of research and decision support needs. ASHG focuses on several fronts: improving the understanding of what hand-held sensor technologies may be able to deliver; communicating what hand-held sensor readings can provide to a number of audiences; the challenges of how to integrate data generated by multiple entities using new and unproven technologies; and defining best practices in communicating health-related messages to various audiences. This review summarizes the challenges, successes, and promising tools of those initial ASHG efforts and Federal agency progress on crafting similar products for use with other NAAQS pollutants and the HAPs.
