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.
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 does LD50 measure?
LD50 (short for lethal dose 50) is the dose of a substance at which it kills 50% of test subjects.
Why does Magnesium Sulfate not have an LD50?
that's not true, in fact magnesium sulfate has been tested on rats and dogs, and it does have an ld50. "The LD50 values were 206 mg/kg for males and 174 mg/kg for females"
What is the antonym for pesticide?
pesticide
What is the LD50 standard?
1mg/kg
What is ld50 of calcium?
30000000 ng
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 LD50 value for plutonium?
A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
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,however LD50 just provide coarse idea and specific adverse effect also need be considered.
