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 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 of thiopental?
thipental
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.
Is a dioxin concentration of 0.04 ppm below the LD50 standard?
yes, it take 130ppm standerd for a mouse -- equilivent to 70 cups of coffee for a human ar one sitting
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 for milk?
The LD50 (lethal dose for 50% of the population) for milk is not well-defined, as milk is generally considered safe for consumption and is not toxic. However, excessive consumption of milk can lead to gastrointestinal distress or other health issues in some individuals, particularly those who are lactose intolerant. In healthy individuals, the amount of milk required to reach a lethal dose would be impractically high and is not typically studied. Thus, milk does not have a standard LD50 value like many toxic substances do.
