Several key concepts are fundamental to the field of toxicology:
Dose-Response Relationship: The relationship between the amount of exposure to a substance and the extent of toxic effect. Threshold Levels: The dose below which a substance is not expected to cause any adverse effects. LD50: The lethal dose for 50% of the population; a common measure of a substance's acute toxicity. Bioaccumulation: The accumulation of a substance in the tissues of living organisms over time. Biotransformation: The chemical modification made by an organism on a chemical compound.
