Acute lethality is commonly measured using the LD50 (Lethal Dose, 50%) value, which represents the dose required to kill 50% of a test population. This measurement is typically conducted on animal models, such as rodents, to determine the toxicity levels of various substances. The LD50 value is expressed in milligrams of substance per kilogram of body weight (mg/kg). Another method is the LC50 (Lethal Concentration, 50%), used for substances that are inhaled.
