What is LD50 of a pesticide?
Lethal dose 50, the dosage at which 50% of animals (usually rabbits, I think) given the chemical die as a result of toxicity.
What is low dose aspirin?
aspirin 81mg
Is low dose aspirin the same as baby aspirin?
81mg is the common dosage for "baby" aspirin
Why would cockarocahes survive a nuclear blast?
Insects have higher LD50 for radiation exposure than mammals. LD50 is defined as the dose of something toxic that results in 50% fatality in the exposed group. However insects would have similar problems to mammals surviving the thermal effects.
What does LD50 measure?
LD50 measures the lethal dose of a substance that causes death in 50% of the test subjects, typically expressed in milligrams of substance per kilogram of body weight. It provides a standardized way to compare the toxicity of different substances.
When a pesticide is sprayed on a population of insects all insects do not get killed but few of them survive give reason?
Poisons are rated by LD50, the dose that kills 50% of a population. The dose can be increased to an LD90, LD99 or whatever but you can never guarantee that the dose will kill them all, as some individuals are more resistant to a specific poison than others are.To get the last few highly resistant individuals may require a dose many orders of magnitude larger than the LD50.
What is the leathal dose of salt?
The human lethal dose of sodium chloride (LD50) is 3 g NaCl/kg body.
What do you mean by LD50 value for heroin?
The 'median lethal dose'. In other words, the average dose that would be enough to kill you
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.
How did you calculate LD50?
Calculating the median lethal dose, LD50 (the dose of a toxin which kills half of the test population) first requires a lot of laboratory testing which can take months. The data is then accumulated and manipulated to give a value which is the median dose. -- Why don't you get to understand Lichfield wilcoxon's method.
What does 'LD50' stand for?
LD50 stands for Lethal Dose 50, a measurement of how much exposure it takes to a certain chemical to kill 50% of a target population. This is usually a calculated value based on lab exposure of the chemical to a population of animals.
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.
