ED50 is part of a family of dose metrics used in toxicology to describe different aspects of the dose-response relationship:
LD50: The dose at which 50% of the population experiences lethal effects, used to assess acute toxicity. TD50: The dose at which 50% of the population experiences toxic effects, indicating the toxicity threshold. NOAEL:No Observed Adverse Effect Level, the highest dose at which no adverse effects are observed, used for chronic exposure assessment.
