This thesis describes the development and the use of quantitative deuterium Nuclear Magnetic Resonance spectroscopy (NMR) as a tool in two areas of environmental research: the study of long term climate-plant interactions and the source tracking of persistent organic pollutant.Long-term interactions between plants and climate will influence climate change during this century and beyond, but cannot be studied in manipulative experiments…
