ld50 for lamotrigine
The human lethal dose of sodium chloride (LD50) is 3 g NaCl/kg body.
The lethal dose (LD50) of sodium chloride for a human being is 3 g NaCl/kg of body in a single intake.
The strength of a poison is determined by its LD50 value (Lethal Dose). The LD50 value is the amount of toxin it takes to kill 50 percent of a population each time a dosing experiment is done in a lab setting. The value is measured by mg/kg of body weight. For example, the LD50 value of salt is 1000 mg.kg body weight, that means that every kg of body weight must contain 1000 mg of salt in it to cause death. The lower the LD50 value, the more potent or deadly the poison is. Remember that death is not the only end point measured in toxicology. There are many poisons that cause severe adverse effects well before they kill someone. Someone may experience things such as paralysis or cognitive disruption at levels much below the LD50 value, and some poisons take much larger doses to cause effects than others. Remember, the dose defines the poison, but the power of the poison is measure technically by the LD50 value.

The radiation LD50 of most insects is far higher than the LD50 of mammals.
LD50 (short for lethal dose 50) is the dose of a substance at which it kills 50% of test subjects.
that's not true, in fact magnesium sulfate has been tested on rats and dogs, and it does have an ld50. "The LD50 values were 206 mg/kg for males and 174 mg/kg for females"
The LD50 (the dose that'll kill half the people who take it) of potassium ferricyanide is 2970mg/kg, which is very nearly the same as the LD50 of table salt. I wouldn't recommend eating any of it - it'll make you sick as a dog if you do - but it won't kill you.

A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
