This proposal is directed toward the Strategic target area of Healthy Environment and Ecosystems and addresses the research topic of Waste Management and Site Remediation, Analytical Tools.There is much concern over the potential hazards of industrial and landfill remediation sites and landfill gas emissions. Hazardous air pollutants (HAP) at sufficient levels can result in negative health effects due to both short-term and long-term exposures.Recent technical advances suggest an opportunity to dramatically improve emissions monitoring through the use of laser technology. Quantification of fugitive emission of pollutants over very large areas will become possible by combining a new laser technology, known as the Quantum Cascade Laser, with a new emissions monitoring technique called Radial Plume Mapping.The first objective of this project is to develop a Quantum Cascade laser suitable for open path spectroscopic analysis of atmospheric pollutants. The second objective is to develop an open path mid infrared spectroscopic analyzer technology that is suitable for use hi the field. The final objective is to apply the new QCL technology to site remediation and other similar applications. The third objective, which will involve field trials, is longer term and beyond the scope of this proposal but would be the outcome of its successful completion. The laser technology will include microelectromechanicalsystems (MEMS) and will be fabricated using Nanotechnology fabrication facilities.The project will involve two companies; Boreal Laser, a manufacturer of laser environmental analyzers and ;Norcada, a MEMS developer and manufacturer. Part of the project will be supervised by two representatives from these companies. The project will also involve a member of the engineering faculty,a member of the science faculty, four students and two research associates.

该提案针对健康环境和生态系统的战略目标区域，并解决了废物管理和场地修复，分析工具的研究课题。工业和垃圾填埋修复场地以及垃圾填埋气体排放的潜在危害备受关注。足够水平的有害空气污染物（HAP）可因短期和长期接触而对健康造成负面影响。最近的技术进步表明，通过使用激光技术，有机会大大改善排放监测。通过将一种新的激光技术（称为量子级联激光）与一种新的排放监测技术（称为径向羽流测绘）相结合，对大面积污染物的逸散排放进行量化将成为可能。该项目的第一个目标是开发一种适用于大气污染物开程光谱分析的量子级联激光器。第二个目标是开发一种适用于该领域的开放路径中红外光谱分析仪技术。最终目标是将新的QCL技术应用于场地修复和其他类似应用。第三个目标将涉及实地试验，这是较长期的，超出了本建议的范围，但将是其成功完成的结果。激光技术将包括微机电系统（MEMS），并将使用纳米技术制造设备制造。该项目将涉及两家公司；Boreal Laser，激光环境分析仪的制造商；诺卡达，一家MEMS开发和制造商。部分项目将由这些公司的两名代表监督。该项目还将涉及一名工程学院成员、一名科学学院成员、四名学生和两名研究助理。
