Polycyclic aromatic hydrocarbons (PAHs) include several hundred chemically-related, environmentallypersistent organic compounds having various structures and varied toxicity. Most of them are formed by aprocess of thermal decomposition (pyrolysis) and subsequent recombination (pyrosynthesis) of organicmolecules from industries such as petroleum and coal PAHs are ubiquitous in Canadian soils and of concernfor human and ecosystem health due to their toxicity as carcinogens, mutagens and immunosuppressants. Theindustrial partner, Qanari Inc., has developed and validated the Safe Soil Tester, a rapid diagnostic tool thatuses a bioluminescent microorganism to qualitatively detect the presence of PAHs in contaminated soils. Whencoupled with global positioning systems, the diagnosis produces maps indicating 'hotspots' of contaminationfor further evaluation, risk assessment and remediation. Current market demands for hand-held technologieshave led Qanari to investigate the possibility of developing a micro-biosensor system that would be a smaller,portable device that is compatible with wireless technology. Qanari and McGill University will collaborate todemonstrate the proof-of-concept of a micro-biosensor and detection system, to determine the feasibility ofmicro-sizing the existing technology. Given the increasingly stringent regulations dealing with contaminationfrom PAHs in upstream oil and gas sites, petroleum storage tank sites, as well as other commercial andindustrial facilities, such a rapid detection system has tremendous commercial potential. The Canadian publicwill benefit from quick screening tools to mitigate the effect of PAHs on human and ecosystem health.

多环芳烃（PAHS）包括数百个与环保的有机化合物，具有各种结构和毒性各异。其中大多数是由热分解（热解）的序列以及随后的有机分子的重组（Pyrosynthessis）形成的，这些行业的毒素和毒性因其毒性而导致的毒性和不受毒性的毒性和毒性，在加拿大的土壤和生态系统中无处不在。工业合作伙伴Qanari Inc.已开发并验证了安全的土壤测试仪，这是一种快速的诊断工具，可快速诊断工具，可生物发光微生物，以定性地检测受污染的土壤中PAH的存在。与全球定位系统结合时，诊断会产生地图，表明污染的“热点”，从而进一步评估，风险评估和补救。当前对手持技术的市场需求使Qanari调查了开发微生物传感器系统的可能性，该系统将是一种较小的便携式设备，与无线技术兼容。 Qanari和McGill University将合作示出微生物传感器和检测系统的概念验证，以确定微小技术的可行性。鉴于在上游石油和天然气场所，石油储罐站点以及其他商业和工业设施中涉及污染的法规越来越严格，因此这种快速的检测系统具有巨大的商业潜力。加拿大的公共意愿受益于快速筛选工具，以减轻PAH对人类和生态系统健康的影响。
