What else can I help you with?
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 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.
Why is LD50 data so useful in dealing with human health and environmental toxins?
LD50 data is useful because it provides a standardized measure of toxicity that allows for comparisons between different substances. It helps determine the potential harm a substance may cause and aids in setting safety regulations and guidelines for exposure levels. Additionally, LD50 data can be used to assess the risk of acute poisoning and to guide medical treatment in cases of exposure to toxins.
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 sarin?
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.
Why is the LD50 of a mouse different from a human's LD50?
ld50 for lamotrigine

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 standard?
1mg/kg
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 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 is the ld50 rating and why is it so important?
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 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
