Lethal dose (LD 50) One such population-level measure is the median lethal dose, LD 50 (lethal dose, 50%). This is defined as the dose required to kill half the members of a specific animal population when entering the animal’s body by a particular route. LD 50 is a general indicator of a substance’s toxicity within a short space of time ...
The LD 50 is a standardized measure for expressing and comparing the toxicity of chemicals. The LD 50 is the dose that kills half (50%) of the animals tested (LD = "lethal dose"). The animals are usually rats or mice, although rabbits, guinea pigs, hamsters, and so on are sometimes used. In all these tests, the dose must be calculated relative ...

Apr 24, 2016 · Dose Descriptor for Acute Toxicity. A common dose-response descriptor for acute toxicity is the LD50 (Lethal Dose 50%). This is a statistically derived dose at which 50% of the individuals will be expected to die. For inhalation toxicity, air concentrations are used for exposure values. Thus, the LC50 (Lethal Concentration 50%) is used.
