  "term": "Death",
  "field": "Chemistry",
  "definition": "The irreversible cessation of all life functions within an individual organism. In the context of ecotoxicology, it serves as the definitive endpoint for measuring the acute toxicity of a chemical substance, signifying the organism's complete failure to survive exposure. This outcome is quantified using metrics like the LD50 (lethal dose, 50%) or LC50 (lethal concentration, 50%), which specify the amount of a substance required to kill half of a test population under defined conditions.",
