Developmental toxicology research aims to prevent adverse reproductive outcomes from environmental exposures. Advances in risk assessment better utilize biological data for improved prediction of developmental toxicants.

Area of Science:

  • Developmental toxicology
  • Reproductive toxicology
  • Environmental health sciences

Background:

  • Preventing adverse reproductive outcomes (e.g., birth defects, low birth weight) is a key goal in developmental toxicology.
  • Risk assessment for developmental toxicants requires integrating diverse biological and mechanistic information.
  • Current challenges include effectively utilizing all pertinent data within the risk assessment framework.

Purpose of the Study:

  • To review recent advancements in the risk assessment process for developmental toxicants.
  • To explore future directions that could revolutionize developmental toxicology risk assessment.
  • To highlight the importance of incorporating biological and mechanistic data into risk assessment.

Main Methods:

  • Qualitative assessment of experimental model appropriateness for extrapolation.
