Lethal Concentration 50 (LC50)

An LC50 value is the concentration of a specific material in the air that will kill 50% of the test subjects (animals, usually) when administered as a single exposure (typically 1 or 4 hours) under specified laboratory conditions. This value allows comparison of the relative toxicity of different materials.
