Lethal concentration

Concentration of a toxic substance that causes the death of a percentage n in a given population, for a given time and in a given experiment (LCn). We speak of LC0 for the maximum tested concentration applied in a single dose and causing no death in the population of studied organisms during a given time. Finally we talk about LC50 for a concentration applied in a single dose and causing 50% mortality in the population of studied organisms for a given time.
