ld50 for lamotrigine
10 doses of cyanide !!!!Potassium cyanide: LD50, Oral Rat = 6 mg/kg.Phorate: LD50, Oral Duck = 0.6 mg/kg (ten times deadlier for ducks than KCN is for rats.)
In toxicology, the median lethal dose, of a toxin is the dose required to kill half the members of a tested population after a specified test duration. LD50 figures are frequently used as a general indicator of a substance's acute toxicity.
Cypermethrin, assuming the LD50s for the two chemicals are for the same period of time. LD50 is the lethal concentration where half of the individuals die in a given time period. Higher numbers mean that is takes more of the chemical to kill organisms, whereas lower numbers mean it takes less of the chemical to kill organisms. LD50s depend on what animal was used in the experiment.
True. The chemical with an LD50 of 1000mg/kg is less toxic than the one with an LD50 of 100mg/kg. LD50 is the lethal dose at which 50% of the test subjects die, so the higher the LD50 value, the less toxic the chemical is considered.
LD50 ('50%-Lethality' dose) is a meaured value from many statical investigations. So there's only a good definition on how it should be 'measured' and can not be calculated from other values by formula.

The radiation LD50 of most insects is far higher than the LD50 of mammals.
The LD50 of methanol for rats is typically around 5628 mg/kg. To calculate the LD50 for a 100 gram rat, you would multiply the LD50 value by the weight of the rat in kilograms (100 grams = 0.1 kg) to get an estimated lethal dose.
A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
The LD50 of phenobarbital in humans is estimated to be around 15 mg/kg when taken orally. LD50 represents the dose at which 50% of the test population would die as a result of the substance.
