项目摘要

DESCRIPTION (provided by applicant): In this proposal we respond to the call by the National Institute of Environmental Health Sciences (NIEHS) in the PHS 2007-2 Omnibus Solicitation for "new products/devices, tools, assays to improve our ability to precisely measure environmental exposures to individuals with high temporal and spatial resolution." According to the solicitation, the device should be of appropriate scale to be field deployable and/or wearable. Ozone, formed in photochemical air pollution, has well documented adverse effects on human health, including reduction of lung function and aggravation of preexisting respiratory disease such as asthma. Emergency department visits, daily hospital admissions and mortality increase during episodes of high ozone concentration. A Personal Ozone Monitor (POM) is required for environmental health studies of the physiological effects of ozone and for validating computer models of human exposure such as the Air Pollution Exposure (APEX) model used by the Environmental Protection Agency to assist in establishing national air quality standards. We propose to develop a small (4 x 3 x 1 inch), light weight (d 1 lb), low power (d 3 watts), low cost (d $800 in parts) battery-operated POM based on the well established method of UV absorbance. The instrument will result from further miniaturization of a backpack-sized instrument already commercialized by 2B Technologies and successfully tested as a personal exposure monitor. The pocket-sized POM will have a precision and accuracy of better than 2 ppb and make new measurements every 10 s. The instrument will have an internal data logger and USB computer interface for downloading data into a personal computer. During Phase I, we will evaluate and select miniaturized components, design and construct a prototype POM, test the prototype for effects of orientation, vibration and rapid temperature and humidity change, and, finally, characterize the instrument with respect to the analytical figures of merit of linearity, precision and accuracy. PUBLIC HEALTH RELEVANCE: A pocket-sized, battery powered Personal Ozone Monitor (POM) will be developed and tested. The POM, which will be based on the well established method of UV absorbance, will facilitate physiological studies of the adverse effects of ozone, formed in air pollution, on human health.

描述（由申请人提供）：在本提案中，我们响应国家环境健康科学研究所 (NIEHS) 在 PHS 2007-2 综合征集中提出的“新产品/设备、工具、检测方法，以提高我们以高时间和空间分辨率精确测量个人环境暴露的能力”的号召。根据招标，该设备应具有适当的尺寸，以便可现场部署和/或可穿戴。光化学空气污染中形成的臭氧对人类健康有明显的不利影响，包括降低肺功能和加重哮喘等已有的呼吸道疾病。在臭氧浓度高的情况下，急诊就诊次数、每日住院次数和死亡率都会增加。个人臭氧监测仪 (POM) 用于臭氧生理效应的环境健康研究以及验证人体暴露的计算机模型，例如环境保护局用于协助建立国家空气质量标准的空气污染暴露 (APEX) 模型。我们建议基于成熟的紫外线吸收方法开发一种小型（4 x 3 x 1 英寸）、轻量（d 1 磅）、低功耗（d 3 瓦）、低成本（零件 800 美元）的电池供电 POM。该仪器是背包大小仪器的进一步小型化的产物，该仪器已由 2B Technologies 商业化，并成功作为个人暴露监测器进行了测试。袖珍 POM 的精度和准确度优于 2 ppb，并且每 10 秒进行一次新的测量。该仪器将有一个内部数据记录器和 USB 计算机接口，用于将数据下载到个人计算机中。在第一阶段，我们将评估和选择小型化组件，设计和构建原型POM，测试原型的方向、振动以及温度和湿度快速变化的影响，最后，根据线性度、精度和准确度的分析品质因数来表征仪器。公共健康相关性：将开发和测试袖珍、电池供电的个人臭氧监测仪（POM）。 POM 将基于成熟的紫外线吸收方法，将促进空气污染中形成的臭氧对人类健康不利影响的生理学研究。
