项目摘要
Contamination of groundwater by organic contaminants represents one of the most urgent challenges facing environmental scientists, industry, government regulators and society. This application addresses directly the Target Area Healthy Environment and Ecosystems, specifically addressing the research topics under Waste Management and Site Remediation, and Water Resources. The proposal focuses on an important group of priority pollutants - chlorinated hydrocarbons - many of which are toxic and confirmed or suspected carcinogens, and which are among the most common contaminants found at sites across Canada in both rural and urban settings. Degradative processes, both biological and abiotic, are a major focus of research on remediation of these contaminants. Estimating the effectiveness of these methods on contaminant attenuation has to date relied primarily on measurement of the concentration of pollutants in field tests, column experiments and laboratory microcosm experiments, and on microbiological approaches to identify key organisms and degradation pathways. In complex, naturally variable field settings however, it is often difficult to quantify reaction rates, and to determine the relative importance of degradation versus other processes of mass loss such as dilution, sorption, and volatilization and to distinguish which of a variety of potential degradation processes are at work. New analytical tools to measure the effectiveness of these methods and technologies are urgently needed. The proposed research addresses this target directly by investigating the use of Compound Specific Isotope Analysis (CSIA) to improve assessment of remediation effectiveness and to predict time required to achieve target clean-up levels (by providing a novel method for estimating rates), and to improve capacity for trouble-shooting and optimizing remedial schemes.
有机污染物对地下水的污染是环境科学家、工业界、政府监管机构和社会面临的最紧迫的挑战之一。该应用程序直接解决目标区域健康环境和生态系统,特别是解决废物管理和现场修复,以及水资源下的研究课题。该提案侧重于一组重要的优先污染物-氯化碳氢化合物-其中许多是有毒的、已确认或疑似致癌物,是加拿大城乡地区最常见的污染物。生物和非生物的降解过程是对这些污染物进行补救的主要研究重点。迄今为止,对这些方法在污染物衰减方面的有效性的估计主要依赖于在实地测试、柱实验和实验室微观实验中对污染物浓度的测量,以及依赖于确定关键生物和降解途径的微生物学方法。然而,在复杂的、自然变化的现场环境中,往往难以量化反应速率,难以确定降解相对于其他质量损失过程(如稀释、吸附和挥发)的相对重要性,也难以区分各种潜在降解过程中的哪一种在起作用。迫切需要新的分析工具来衡量这些方法和技术的有效性。拟议的研究解决这一目标直接调查使用的化合物特定同位素分析(CSIA),以改善评估的补救效果和预测所需的时间,以达到目标的清理水平(通过提供一种新的方法估计率),并提高故障排除和优化补救方案的能力。
