## Abstract

ABSTRACT: UC DAVIS SUPERFUND RESEARCH PROGRAM
Superfund sites are diverse, and many include unknown chemicals, chemicals of unknown toxicity and/or toxic
degradation products. Currently, methods to detect, prioritize, and remediate these chemicals are incomplete
or nonexistent. The UC Davis Superfund Research Center (UCD-SRC) will conduct research to: (i) improve
understanding of the mechanisms by which hazardous chemicals produce adverse health effects, (ii) develop,
validate and integrate novel methods to evaluate chemical exposures, levels of contamination, and health
risks, and (iii) develop innovative remediation strategies to reduce hazardous substance exposure and toxicity.
To achieve these goals the SRC consists of 5 integrated projects, 2 research support cores, a training core, a
community engagement core, a research translation core and an administrative core. The UCD-SRC will use
integrated chromatographic, biosensor and cell based technologies to detect and identify contaminants and
develop innovative approaches for bioremediation. Rapid immunochemical and cell based analysis will
supplement classical technologies for the evaluation of sites, as well as determining human susceptibility,
exposure and effect. Fundamental mechanisms of toxic action of selected chemicals will be explored to predict
risk and develop new biomarkers. This mechanistic knowledge will be extended in vivo with an emphasis on
mechanism of toxicity. We are expanding the use of transcriptomics, proteomics, metabolomics and integrated
bioinformatics technologies to discover new mechanisms of action of hazardous materials and biomarkers for
their action and to connect hazardous substance exposures to organism level effects. The biomarkers
developed in this project will serve as biological dosimeters in exposure studies. All aspects of the program will
be connected to our Community Engagement Core, and subject to community approval will be demonstrated
on Yurok Tribal Lands. Technologies developed by the SRC will be tested at field sites and transferred to end
users through a research translation core.
Program Relevance
We will develop sensitive systems for evaluating and mitigating the risk of hazardous chemicals on human
populations and the environment using biomarkers of both exposure and effect.
