Groundwater is a vital part of our modern society, supplying a significant amount of the water we use in our homes, agricultural fields and industries every day. Given its importance, we are all affected by the environmental, health, and economic consequences when groundwater is polluted with hazardous chemical contaminants. Characterizing the nature and extent of contamination present at a site is a key step when developing risk assessments and implementing remedial solutions for contaminated groundwater.
Conventional analytical approaches are usually designed for the targeted analysis of a suite of suspected contaminants. These methods, however, often fail to identify compounds that are not normally analyzed for, including degradation products, proprietary chemicals, and other species for which standards are not readily available. NMR spectroscopy provides a unique analytical approach to present a more complete and unbiased understanding of the nature and extent of organic compounds present at contaminated sites undergoing assessment and monitoring activities.
This poster discusses the use of 1D and 2D NMR experiments, including 1H, 13C, 19F, TOCSY, HSQC, DOSY and homonuclear J-Resolved, for the non-targeted analysis of constituents present at heavily contaminated sites.
In April 2017, a campus-community event (N=42 participants) was held to promote sustainable food systems by educating participants about concepts ranging from food production to nutrition and food waste management. This poster discusses the resulting increased awareness and knowledge of a our local food system among participants, which can be fostered through educational events that combine opportunities for research, teaching, and practice.READ MORE
Inflammatory bowel diseases (IBD) often present in adolescence and affect >1.4 million persons in the US. Environmental exposures, notably air pollution and weather, have been suggested to contribute to IBD disease activity. Our goal was to evaluate relationships between environmental exposures and the prevalence and disease activity of pediatric IBD using novel data sources that take into account geographic location.READ MORE
