Event Overview:

Per- and poly-fluoroalkyl substances (PFAS) are persistent chemicals commonly found in surface protectants and fire-fighting foams. Research has revealed that exposure to environmentally relevant concentrations of some PFAS can reduce reproductive success and have other adverse effects on animals. In this webinar, Professor Todd Anderson, from the Department of Environmental Toxicology, Texas Tech University, presents new findings from field studies determining PFAS concentrations in plant and animal tissues. His team have been involved in laboratory and field studies where it was necessary to determine PFAS concentrations in plant and animal tissues to (1) better understand the pathways of PFAS trophic transport from soil to higher organisms, and (2) to determine PFAS burdens in exposed organisms and the potential for maternal transfer of PFAS from adults to offspring.

LC-MS analytical methods for PFAS determination in water and soil matrices provide a solid foundation upon which to make slight changes to improve method performance for extracts of plant and animal tissues. In controlled laboratory studies with an avian model, we’ve used these modified methods with varying degrees of success, to measure PFAS in adult livers, eggs, hatchling livers, and brain tissue (adults and hatchings). These PFAS measurements in tissues allowed for determination of avian Toxicity Reference Values based on survival, growth, and reproduction endpoints, as well as maternal transfer from exposed adults to unexposed hatchlings. In field studies on historical fire training areas, we’ve used these modified methods on a limited set of PFAS analytes, to measure PFAS in vegetation, invertebrates, and small mammal livers. These PFAS measurements have allowed us to better understand the trophic transport pathway(s) from soil to higher organisms based on diet (herbivores, insectivores, omnivores) or activity (grooming, nest building).

Key Learning Objectives:

• Understand the pathways of PFAS trophic transport from soil to higher organisms
• Determine PFAS burdens in exposed organisms
• Estimate the potential for maternal transfer of PFAS from adults to offspring

Who Should Attend:

• Lab managers and researchers involved in PFAS analysis in food, clinical, environmental, and industrial field
• Researchers interested in expanding their PFAS analysis into the toxicological effects associated with PFAS exposure

Speakers:

Todd Anderson
Presidential Research Excellence Professor
Department of Environmental Toxicology, Texas Tech University

Todd Anderson is a Presidential Research Excellence Professor in the Department of Environmental Toxicology and The Institute of Environmental and Human Health (TIEHH) at Texas Tech University. His teaching and research focus on the movement and analysis of chemical contaminants (pollutants) in the environment. The ultimate objective is to evaluate and better characterize potential exposure of organisms to contaminants. An important set of supporting experiments involve specifically testing for the effects of selected chemicals using both invertebrate and vertebrate models. He received his M.S. and Ph.D. from the University of Tennessee, Knoxville under the direction of Barbara Walton at Oak Ridge National Laboratory (ORNL); he did postdoctoral research in pesticide toxicology and fate at Iowa State University with Joel Coats.
