Inexpensive Monitoring Network Assess Workplace

项目摘要

DESCRIPTION (provided by applicant): Personal exposure sampling is the primary means to ensure that chemical and physical hazards in the workplace are maintained below occupational exposure limits. Typically few exposures are measured to represent a large working population because personal sampling is expensive and time consuming. Hence, most decisions regarding the extent to which workers are protected are based on extremely sparse data. Incorporation of distributed networks of inexpensive sensors has the potential to provide dramatic gains in the information content available for understanding the components of exposure variability, which are critical to evaluating and mitigating workplace risk. The laboratory and field work outlined in this application will develop and use a novel distributed monitoring network based on newly available, inexpensive aerosol sensors with worker tracking to estimate personal exposures. With successful completion of the proposed work, there will be many benefits, including information on operating and performance of inexpensive sensors and a network- deployable monitor (Aim 1), a method to optimize the number and placement of monitors within an occupational setting (Aim 2), and a method to integrate network and worker tracking data to estimate personal exposures (Aim 3). The new exposure assessment framework emerging from this development work will be applied in two year-long field studies at industrial workplaces to demonstrate its general utility and assess its reliability in diverse situations. Analyses of the dta from field studies is expected to demonstrate how the distributed monitoring network can be used to evaluate hazard risk at different time scales relevant to acute (e.g., 15-min) and chronic exposures (e.g., 8-hr, 40-hr, or longer; Aim 2). Further analyses conducted in Aim 3 are expected to show that network-derived personal exposures compare favorably to conventionally-measured personal exposures, approaching or meeting NIOSH criteria for method equivalence. Compared to conventional personal sampling, these new framework will enable an unprecedented increase in exposure measurements (1,000X to 10,000X). This dramatic increase in sample size, even if somewhat less accurate and precise than conventional sampling, will make comprehensive exposure assessment possible in routine industrial hygiene practice, medical surveillance, and epidemiological study. Moreover, the framework is sufficiently general to apply for any physical or chemical agent depending on sensor availability. Consequently, the results of this work will be directly applicable to many sectors of the National Occupational Research Agenda (NORA).

描述（由申请人提供）：个人接触采样是确保工作场所的化学和物理危害保持在职业接触限值以下的主要手段。通常，测量很少的暴露量即可代表大量工作人群，因为个人采样既昂贵又耗时。因此，大多数有关工人受到保护程度的决策都是基于极其稀疏的数据。廉价传感器的分布式网络的结合有可能在可用于了解暴露变异性组成部分的信息内容方面提供巨大的收益，这对于评估和减轻工作场所风险至关重要。实验室和现场工作概述该应用程序将开发和使用一种新颖的分布式监测网络，该网络基于新推出的廉价气溶胶传感器，可跟踪工人以估计个人暴露情况。随着拟议工作的成功完成，将会带来许多好处，包括有关廉价传感器和网络可部署监视器的操作和性能的信息（目标1），一种优化职业环境中监视器的数量和放置的方法（目标1）。 2），以及一种整合网络和工人跟踪数据以估计个人暴露的方法（目标 3）。这项开发工作中出现的新暴露评估框架将应用于工业工作场所为期两年的实地研究，以证明其通用性并评估其在不同情况下的可靠性。对现场研究的 DTA 分析预计将证明如何使用分布式监测网络来评估与急性（例如 15 分钟）和慢性暴露（例如 8 小时、40 小时）相关的不同时间尺度的危害风险。，或更长；目标 2)。目标 3 中进行的进一步分析预计将表明，网络衍生的个人暴露优于传统测量的个人暴露，接近或满足 NIOSH 方法等效标准。与传统的个人采样相比，这些新框架将使暴露测量得到前所未有的增加（1,000 倍至 10,000 倍）。样本量的急剧增加，即使比传统采样的准确性和精确性稍差，也将使常规工业卫生实践、医疗监测和流行病学研究中的全面暴露评估成为可能。此外，该框架足够通用，可以根据传感器的可用性适用于任何物理或化学试剂。因此，这项工作的结果将直接适用于国家职业研究议程（NORA）的许多领域。
