What is the LD50 of ethanol?
The LD50 of ethanol (the lethal dose required to kill 50% of a population) is approximately 10 grams per kilogram of body weight when ingested orally. This can vary based on factors such as individual tolerance and health conditions.
How fast can chlorine gas kill someone?
Chlorine gas can be fatal within minutes to hours of exposure, depending on the concentration of the gas inhaled. Inhaling chlorine gas can cause severe respiratory distress, leading to asphyxiation. Immediate medical treatment is necessary if someone has been exposed to chlorine gas in order to prevent serious injury or death.
Lethal dose of potassium chloride?
Orally, KCl is toxic in excess; the LD50 is around 2500 mg/kg (meaning that a lethal dose for 50% of people weighing 75 kg (165 lb) is about 190 g (6.7 ounces), or about 38 teaspoons). Table salt is about as toxic. Intravenously this is reduced to just over 100 mg/kg, but of more concern are its severe effects on the cardiac muscles; high doses can cause cardiac arrest and rapid death, ergo its aforementioned use as the third and final drug delivered in the lethal injection process.

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.
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.
The oral ld50 value for cypermethrin is 247 mgkg compared to 5000 mgkg for hexaflumuron therefore what is the more toxic of these two pesticide?
Cypermethrin, assuming the LD50s for the two chemicals are for the same period of time. LD50 is the lethal concentration where half of the individuals die in a given time period. Higher numbers mean that is takes more of the chemical to kill organisms, whereas lower numbers mean it takes less of the chemical to kill organisms. LD50s depend on what animal was used in the experiment.
What is the most dangerous LD 50 value 500 or 17.5?
An LD50 value of 17.5 milligrams would be considered far more dangerous than an LD50 value of 500 milligrams. The LD50 value for any drug or other chemical compound is the minimum lethal dose that kills 50% of test subjects (tests are usually conducted on rats and mice). Thus the lower the value, the more toxic the drug.
Why is the LD50 of a mouse different from a human's LD50?
ld50 for lamotrigine
Why does Magnesium Sulfate not have an LD50?
Magnesium sulfate does not have a specific LD50 value because it is not regarded as acutely toxic in typical exposures seen in therapeutic applications. It is commonly used as a medication, mainly for maternal eclampsia and as a supplement to correct magnesium deficiency.
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.
Is14 butanediol the same as propylene glycol as far as ingesting one or the?
No. 1,4-butanediol is significantly more toxic. The MSDS for propylene glycol lists an oral LD50 of 20g/kg in rats, while that for 1,4-butanediol says its LD50 for rats is 1.5g/kg.
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 is the LD50 of pure silver?
LD50 relates to the compound/element, not to poisoning - it is the LD50 of mercury. It varies depending on route of exposure and the animal tested but it is around 1 to 15 mg/kg body-weight.
What is the toxic dose of oxycodone?
105 mgs per day is the average dose. Sources rxlist.com Drugs.com
What is the difference between a toxin and poison?
The way that toxic materials are defined is by how well they kill rats. This is called the "Median Lethal Dose" or LD50. It is usually expressed as "LD50, Oral, Rat" meaning that the subjects were specially bred, white, Norway rats and the dose was given by mouth. The dose is presented as milligrams per kilogram of rat.The U.S. EPA and OSHA define a toxin as a substance that has an LD50 of 500 mg/Kg or less. Acutely toxic materials have an LD50 of 50 mg/Kg or less.The U.S. DOT defines poison as a substance with an LD50 of 200 mg/kg or less.
