可穿戴监测器能够可靠、准确、连续地测量各种有毒物质的个人暴露水平，不仅可以加速当前的环境和职业健康与安全研究，而且还可以实现当前监测技术无法实现的新研究。开发这样的监测器一直是一个艰巨的挑战，需要创新的传感科学和创造性的工程。我们开发、制造并测试了一种可穿戴监测器，用于实时检测环境中的有毒碳氢化合物和酸。该监测器成本低，准确，用户友好。此外，它可以与手机进行无线通信，在手机中可以处理，显示，存储和传输到指定的计算机。我们验证了监测器的功能和性能，并对从事废物管理、消防检修和地板清洁活动的工人以及第一和第二手吸烟者进行了现场测试。平均暴露水平与标准NIOSH方法测定的水平一致。该监测仪为涉及不同活动的工人提供准确和实时的暴露评估。实时和连续的监测能力使得有可能将暴露水平与微环境中的不同活动和变化相关联。该监测仪提供了前所未有的实时信息，将有助于推进职业安全和环境健康研究。它也可以用来更好地保护工人免受职业性过度暴露于有毒分子。Journal of Exposure Science and Environmental Epidemiology（2011）21，419-426; doi：10.1038/jes.2010.35; 2010年6月16日在线发表
A wearable monitor that can reliably, accurately, and continuously measure personal exposure levels of various toxicants would not only accelerate the current environmental and occupational health and safety studies, but also enable new studies that are not possible with the current monitoring technology. Developing such a monitor has been a difficult challenge, and requires innovative sensing science and creative engineering. We have developed, built, and tested a wearable monitor for real-time detection of toxic hydrocarbons and acids in the environment. The monitor is low-cost, accurate, and user friendly. In addition, it can communicate wirelessly with a cell phone in which the monitoring results can be processed, displayed, stored, and transmitted to a designated computer. We have validated the functions and performance of the monitor, and carried out field tests with workers involving waste management, fire overhaul, and floor-cleaning activities, as well as with first- and second-hand smokers. The averaged exposure levels are in agreement with those determined by the standard NIOSH methods. The monitor provides accurate and real-time exposure assessment for the workers involving different activities. The real-time and continuous monitoring capability makes it possible to correlate the exposure levels with different activities and changes in the microenvironments. The monitor provides unprecedented real-time information that will help advance occupational safety and environmental health studies. It may also be used to better protect workers from occupational overexposure to toxic molecules.
