中文摘要
腔衰荡光谱(CRDS)的最新发展使实时监测痕量温室气体(GHG)和这些温室气体在大气浓度下的稳定碳同位素比率成为可能。我们将在环境研究中使用CRDS系统,以更好地了解甲烷(CH4)同位素系统在以下方面的研究:1)导致水生和湿地生态系统温室气体通量的自然过程;2)水文条件变化对农业、水生和湿地系统甲烷通量的影响;3)乙醇和生物燃料污染地下水的影响;4)乙醇、生物燃料和石油碳氢化合物的生物降解,导致蒸汽侵入浅层环境。
英文摘要
Recent developments in cavity ring down spectroscopy (CRDS) allow real time monitoring of trace greenhouse gases (GHG) and stable carbon isotopes ratios of these GHGs at atmospheric concentrations. We will use a CRDS system in environmental research to better understand methane (CH4) isotope systematics in the study of 1) natural processes contributing to GHG flux in aquatic and wetland ecosystems 2) the impact of changing hydrologic conditions on methane flux from agricultural, aquatic and wetland systems 3) the impact of ethanol and biofuel contamination of groundwater and 4) the biodegradation of ethanol, biofuel and petroleum hydrocarbons leading to vapor intrusion into the shallow environment.
