Laser analysis of brownfield emissions

这项建议是针对健康环境和生态系统的战略目标区域，并针对废物管理和场地修复的研究主题，分析工具。人们非常关注工业和垃圾填埋场修复场地的潜在危险和垃圾填埋场气体排放。有害空气污染物(HAP)水平足够高，无论是短期暴露还是长期暴露，都会对健康造成负面影响。最近的技术进步表明，通过使用激光技术可以极大地改善排放监测。通过将一种名为量子级联激光器的新激光技术与一种名为径向羽流映射的新排放监测技术相结合，将有可能对非常大范围内的污染物逃逸排放进行量化。该项目的第一个目标是开发一种适用于大气污染物的开路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式中红外光谱分析技术。最终目标是将新的QCL技术应用于现场补救和其他类似应用。第三个目标将涉及实地试验，这是一个较长期的目标，超出了本提案的范围，但它将是成功完成该提案的结果。激光技术将包括微电子机械系统(MEMS)，并将使用纳米技术制造设施进行制造。该项目将涉及两家公司：激光环境分析仪制造商Boreal激光和MEMS开发商和制造商Norcada。该项目的一部分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教员、一名理科教员、四名学生和两名研究助理。

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.
