Threshold-effect concentration

{
  "id": "MLC-T-CHM-012034",
  "term": "Threshold-effect concentration",
  "field": "Chemistry",
  "definition": "The lowest concentration of a substance at which a statistically significant adverse effect is observed in a test organism or population under defined experimental conditions. This value is used in ecotoxicology to assess the potential harm of pollutants to ecosystems. It is often determined through dose-response studies and is related to the no-observed-effect concentration (NOEC).",
