It's a measure of how toxic a substance is. LD50 stands for lethal dose 50--it's the amount that, when given to a group of laboratory rats, will kill 50% of them. Often expressed in milligrams per kilogram of body weight (since it usually takes more poison to kill a bigger animal).

What is meant by ratting of fuse?
A fuse is given a various rating (strength). For instance, a home appliance (washing machine, etc) would usually have a fuse with a 13 amp rating. While a low powered lamp would only merit a 2 or 5 amp fuse rating. It is important to use a fuse of the correct rating in amps for each electrical appliance.
What is ten time more deadly than cyanide?
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.)
What kind of hazard does poisonous describe?
Poisonous describes the deleterious effect of a chemical upon a living system. Poisonous chemicals are quantified in their effect by the quantity required to kill 50% of a given organism by body mass (Median Lethal Dose or LD50). US DOT defines poisonous as a material having an LD50 oral, rat of 200 mg/Kg or less.
What is a BIA rating?

Trailer axle rating is 45000 pounds how many tons can they haul?
a ton is 2000 pounds so divide 45000/2000 so 22.5 tons
Why is the LD50 of a mouse different from a human's LD50?
ld50 for lamotrigine
True or False. Does a chemical with a LD50 of 1000mg over kg have less toxicity than one with LD50 of 100mg over kg?
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.
What is the ld50 of thiopental?

Why do cockroaches survive a nuclear bomb?
The radiation LD50 of most insects is far higher than the LD50 of mammals.
What is the LD50 of methanol for a 100 gram rat?
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.
What is the LD50 standard?
1mg/kg
What is the formula used in calculation of ld50 of a substance?
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.
What is the LD50 value for plutonium?
A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
What is the LD50 of phenobarbital?
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.
What does High LD50?
A high LD50 (lethal dose for 50% of the population) indicates that a substance is relatively less toxic, as it takes a larger amount of the substance to cause death in half of a test population. In toxicology, a high LD50 value suggests that the compound is safer and poses a lower risk of toxicity compared to substances with a low LD50, which require smaller doses to achieve lethal effects. Therefore, when evaluating the safety of chemicals or drugs, a high LD50 is generally seen as favorable.
10 rats given LD50 dose of aspirin how many rats survive?
by definition ld50 is when 50% survive or dead,,answer will be 5 if i count well
What is the LD50 of caffeine, and what implications does this have for its potential toxicity in humans?
The LD50 of caffeine is estimated to be around 150-200 milligrams per kilogram of body weight in humans. This means that half of the population would likely die if they consumed this amount. The implications of this high LD50 value suggest that caffeine is relatively safe in moderate amounts, but can be toxic in excessive doses. It is important for individuals to be mindful of their caffeine intake to avoid potential health risks.
