WASHINGTON (August 3, 2020) — Today, the U.S. Environmental Protection Agency (EPA) announced $3,980,782 in funding to five academic research teams to develop New Approach Methods (NAMs) for evaluating chemical toxicokinetics, an important aspect of evaluating the impacts of chemicals on human health and the environment. Compared to traditional animal testing, NAMs allow researchers to better predict potential hazards for risk assessment purposes without the use of traditional methods that rely on animal testing.

“These awards will be used to develop tools that help industry and EPA evaluate the safety of chemicals more quickly and cheaply,” said EPA Administrator Andrew Wheeler. “This research will be another step toward EPA’s goals of more widespread application of NAMs and reduction in animal testing.”

Each research team is receiving a grant of up to $800,000 through EPA’s Science to Achieve Results (STAR) Program. Their projects will address gaps in ways to obtain data for informing chemical toxicokinetics and exposure-related factors not currently considered. Toxicokinetics are an important component of understanding how chemicals can impact health by looking at chemical concentrations that cause changes at the cellular or molecular level. New methods, tools, and approaches can improve our ability to predict a chemical’s health impacts and reduce uncertainty as the science moves from laboratory approaches to real world scenarios.

The five recipients include:

  • Purdue University, West Lafayette, Ind., to create an integrated blood brain barrier computer model to help determine if a chemical may cause neurotoxicity.
  • Texas A&M University, College Station, Texas, to help integrate different types of chemical safety testing for more robust results.
  • University of Nevada, Reno, Nev., to develop better estimations of the bioavailability of chemicals in order to assess the significance of public exposure. 
  • Vanderbilt University, Nashville, Tenn., to work on methods to refine organ-on-chip devices for chemical testing.
  • Woods Hole Oceanographic Institution, Woods Hole, Mass., to determine how zebrafish metabolism can be better correlated to the human metabolism to improve models for chemical toxicity testing
