Abstract

The tremendous advancements realized through human genome sequencing serve to illustrate the critical role that environmental factors play in the etiology of human disease. Similarly, continued improvements in analytical instrumentation have resulted in the ability to obtain vast amounts of metabolomics data. Despite these advances, methodologies that directly link environmental exposures to metabolic condition and human disease remain elusive. The overall goal of our environmental metabolomics research program is to develop and demonstrate the efficacy of dual-platform biomonitoring approaches, based on state-of-the-art separation and detection methods, to monitor exposures and elucidate metabolic impacts of environmental toxicants. The methodology combines trace analysis of toxicant levels using gas-chromatography mass selective detection (GC-MSD) with high-throughput metabolic profile assessment using liquid chromatography tandem mass spectroscopy (LC-MS/MS). Examples of both targeted and non-targeted (“top-down”) analysis of toxicant exposures and corresponding metabolic responses will be presented to demonstrate applicability of the dual platform approach to a range of exposure scenarios.
