Development of a Margin of Exposure and Safe Exposure Concentration for Tetrabromobisphenol A (TBBPA)

The study developed a cancer-based and a non-cancer based toxicity value and compared those values to appropriate estimates of human exposure to TBBPA. The data collectively indicated a low level of health concern associated with exposures to TBBPA based on current data.1Source: Wikoff, Daniele, Chad Thompson, Camarie Perry, Matthew White, Susan Borghoff, Lauren Fitzgerald, and Laurie C.

Key Takeaways:

  • The evaluation found margin of exposure (MOE) estimates of 32,000,000 and 800,000.
  • MOE demonstrates that even when maximum concentrations of TBBPA in the diet, breast milk, soil/dust and water were used the resulting exposures were many orders of magnitude below any reported adverse effects seen in research animal studies.
