What does LD50 mean? - Correct Answer Lethal dose (LD50) is the amount of an
ingested substance that kills 50 percent of a test sample. It is expressed in mg/kg, or
milligrams of substance per kilogram of body weight.
The lower the amount, the higher the toxicity. This is because it took less of the
substance to kill 50% of test subjects.
LD 50 is ratio mg of poison / kg of body weight.
So the smaller the LD50 number the MORE toxic it is.
Most Dangerous compound:
Botulinum LD50 (0.000009) = 9 ng/kg
Cyanide LD50 (6.8)
Comparing:
Atrazine Herbicide LD50 (3000)
Caffeine LD50 (200)
So it would take 15 times more atrazine to kill you than caffeine.
