On the "perfect killers"

Trying to figure out what the poison is strongest in nature, it is doomed to failure - too many variables affect the results. However, if you take only one parameter - the average lethal dose, only one species of living creatures - laboratory mice, only one route of administration - intramuscular, evaluate not solid poisons and their individual components, then some idea of ​​the "perfect killers" to get possible .

Average lethal dose, DL50 (lat. Dosis letalis), causes the death of half of the experimental animals (DL100 - the dose is minimal enough to kill anyone who got it). DL measured in milligrams of substance per 1 kg of animal body weight (mg / kg), the rating is given in parentheses after the name of the substance. Thus, the top 10 of the most toxic poisons with DL50 - mice when administered intramuscularly.
