Lethal concentration definition

Lethal concentration or "LC50" means the toxicant concentration killing 50 percent of the exposed organisms in a specific time of observation.
Lethal concentration means the median lethal concentration level, at which 50 percent of appropriate test animals die when exposed by inhalation for a scientifically appropriate specified time period.
