  "term": "Effect time",
  "field": "Chemistry",
  "definition": "The duration of exposure to a toxicant required to produce a specified effect in a given percentage of a population. This metric is used in ecotoxicology to characterize the speed at which a harmful outcome manifests after the onset of exposure. It is often expressed as LT50 (lethal time 50%), indicating the time at which 50% of the exposed population exhibits a lethal effect.",
