Susceptibility is often measured using dose-response relationships. These relationships help toxicologists determine the concentration of a substance that causes a specific effect in a certain percentage of the population. Key metrics include:
LD50: The dose of a substance that is lethal to 50% of a test population. NOAEL: No Observed Adverse Effect Level, the highest dose at which there are no significant adverse effects observed. LOAEL: Lowest Observed Adverse Effect Level, the lowest dose at which there are significant adverse effects.
