  "id": "MLC-T-CHM-004305",
  "term": "Extrapolation factor",
  "field": "Chemistry",
  "definition": "A numerical factor used in risk assessment to account for uncertainties when extrapolating toxicity data from one species to another, or from high-dose experimental conditions to low-dose environmental exposures. These factors are applied to derive safe exposure levels. They typically range from 1 to 1000, depending on the type and magnitude of uncertainty.",
