This would be impossible to achieve.
Excessive consumption would lead to vomiting, preventing any futher ingestion of water.
Edit: the person that initially answered this is wrong. Water does have an LD50, and for rats it's 90 ml/kg. It should be something similar to that for humans. Here's a woman that died in a water drinking contest from water intoxification: http://www.msnbc.msn.com/id/16614865/
This has nothing to do with the presence of water, but rather the lack of electrolytes such as salt. Drinking water uses up your body's "supply" of salt, and if it gets used up completely, your brain can no longer transmit electrical signals and you die. If you get a steady supply of salt with the water, you won't have any problems no matter how much water you drink, but as the first answer said, there is a limit to how much water you can drink before your body refuses to take any more, and anything you drink just gets vomited out.
The way that toxic materials are defined is by how well they kill rats. This is called the "Median Lethal Dose" or LD50. It is usually expressed as "LD50, Oral, Rat" meaning that the subjects were specially bred, white, Norway rats and the dose was given by mouth. The dose is presented as milligrams per kilogram of rat.The U.S. EPA and OSHA define a toxin as a substance that has an LD50 of 500 mg/Kg or less. Acutely toxic materials have an LD50 of 50 mg/Kg or less.The U.S. DOT defines poison as a substance with an LD50 of 200 mg/kg or less.
LD50 or LC50 refers to the dose of a substance that is lethal to 50% of the test population. For phosphoric acid, the LD50 (oral, rat) is estimated to be around 1530 mg/kg. LC50 (inhalation, rat) is not readily available. As with any substance, caution should be taken when handling phosphoric acid due to its potential toxicity.
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.
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.
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.
No. 1,4-butanediol is significantly more toxic. The MSDS for propylene glycol lists an oral LD50 of 20g/kg in rats, while that for 1,4-butanediol says its LD50 for rats is 1.5g/kg.
by definition ld50 is when 50% survive or dead,,answer will be 5 if i count well
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.)
192mg/kg in rats. Less immediately available information for humans.
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.

The acute oral LD50 of alprazolamin rats is 2171 mg/kg.Assuming similar toxicity in humans (which is an assumption that has many faults) a 70 kg person would have a 50% of dying if they consumed about 145g that is over 500 0.25g tablets.
The exact amount in humans is uncertain as such an experiment would be unethical. In rats the LD50 is 2000 mg/kg (LD50 is the dose that kills 50% of those getting it). A dose much less than this will cause some damage in almost all. The Lowest Published Lethal Dose (LDL) [Human Infant] - Route: Oral; Dose: 442 ku/kg/11D.
The LD50/50 (50% mortality in 50 days) for strontium-90 in rats is estimated to be around 2.5 to 3 microcuries per gram of body mass. I do not know if that translates linearly to humans.
According to the Fisher Scientific MSDS for bleach, the oral LD50 in rats is >90 mL per kilogram of body weight. So if you're worried about bleach poisoning, you'd have to drink a lot for it to kill you. It does have other harmful effects at lower doses, however.
Glutamate has a very low acute toxicity under normal circumstances; the oral dose that is lethal to 50% of subjects (LD50) in rats and mice is ~15,000--18,000 mg/kg body weight, respectively. Normally spoken when a salt is consumed by a human it is dissolved, whether it's in pure water or in water contaminated with alcohol. Death by saltcaused-dehydration has an extremely painful trajectory.
