Chemistry and Analytical Core (CAC)

We provide critical research support by contributing expertise and analytical capabilities to measure toxic substances with prioritization of inorganic arsenic and co-occurring contaminants.

Our overarching goal is to develop and apply ultra-sensitive and specific analytical methods to measure metals, specifically inorganic arsenic, in environmental and biological samples and characterize toxicant-induced adverse health effects via microbiome and biomarker/metabolomics approaches.

The overarching goal of the CAC is to develop and apply ultra-sensitive and specific analytical methods to measure metals.

The Chemistry and Analytical Core (CAC) offers analytical expertise and services including access to state-of-the-art instrumentation for metals measurements, microbiome and biomarker/metabolomics analysis, and training in cutting-edge research methodologies. Furthermore, we provide Projects 1-5 with the tools and expertise needed to generate critical data sets that will help to identify novel strategies to reduce inorganic arsenic exposure and to present inorganic arsenic-induced metabolic dysfunction.

Our activities promote interaction among all Projects and Cores through expertise in metals analyses, microbiome and biomarker/metabolomics analysis that is critical in guiding the Projects’ research strategies.
