563 mg or about 0.8 milliliters.
A rat's normal temperature ranges from 100-103F [38-39C]
a brown rat is a carnivore
We call them rats because their scientific name is Rattus norvegicus. All the pet and lab rats are belonging to this species. The tiny black colour, house hold rats are under the species of Rattus rattus.The strain name depends on what kind of rat it is.l
Yes, rat snakes can be gray with black markings. The gray rat snake, also known as the black rat snake, is a common species that is usually gray with dark blotches or markings along its body. These snakes are non-venomous and can be found in a variety of habitats across North America.
It seems like there might be a typing error or misunderstanding. "Kee-rat" is not a recognized term or concept. If you can provide more context or clarification, I'd be happy to try and help.
LD50 or LC50 refers to the dose of a substance that is lethal to 50% of the test population. For phosphoric acid, the LD50 (oral, rat) is estimated to be around 1530 mg/kg. LC50 (inhalation, rat) is not readily available. As with any substance, caution should be taken when handling phosphoric acid due to its potential toxicity.
dear sir i need complete information about NOEL calculation in cleaning validation
A poisonous mushroom is a poisonous mushroom
No, it is not considered poison. OSHA and the EPA define toxic as substances with an oral rat median lethal dose (LD50) 500 mg / Kg or less, The DOT and IATA/ICAO use LD50, oral rat, 200 mg / Kg or less as the definition for poison for shipping hazardous materials and dangerous goods. Ethyl alcohol, found at concentrations around 6% in beer has an LD50, oral rat, variously reported between 7060 to 12,000 mg / Kg. Anything, though, can poison you if taken in large doses. There was a recent story of a woman who poisoned herself with water trying to win a Wii from a radio station's contest. See Link.
10 doses of cyanide !!!!Potassium cyanide: LD50, Oral Rat = 6 mg/kg.Phorate: LD50, Oral Duck = 0.6 mg/kg (ten times deadlier for ducks than KCN is for rats.)
Poisonous describes the deleterious effect of a chemical upon a living system. Poisonous chemicals are quantified in their effect by the quantity required to kill 50% of a given organism by body mass (Median Lethal Dose or LD50). US DOT defines poisonous as a material having an LD50 oral, rat of 200 mg/Kg or less.
"Poison" is defined by the Department of Transportation (DOT) as anything with an LD50 Oral Rat less than 200 mg/Kg. Toxic is defined by the Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) as anything with an LD50 Oral Rat less than 500 mg/Kg and acutely toxic substances have an LD50 Oral Rat less than 50 mg/Kg. After scanning several MSDSs at the site below, it appears that none of the Lysol(R) brand products would, by themselves, be toxic by definition. Some preparations do contain phenol which has an LD50 Oral Rat of 317 mg/Kg. Phenol is, therefore, toxic by definition but the formula that contains a small percent of phenol would not necessarily be toxic. Probably the greatest risk is not from being poisoned, but from the corrosive effect from those formulas that contain sodium or potassium hydroxide. There are a few MSDSs that warn against inducing vomiting if ingested because of the tissue damage that would result. Find your product and read the MSDS. Everything can kill you...there was a woman who recently died from drinking too much water. It is good advice to avoid drinking Lysol.

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.
An accurage Lethal Dose for the drug Zopiclone in humans does not seem to be currently available. This information may be useful. History: A 72-year-old hospitalized male died following an intentional overdose of 90 milligrams of zopiclone. The patient was being treated for lung cancer and died approximately 4 to 10 hours after the ingestion (Meatherall, 1997). The authors suggested this may be a minimum lethal dose considering the patient's age, weakened condition and arteriosclerosis. Meatherall RC: Zopiclone fatality in a hospitalized patient.

I can tell u that during my drug abuse days I once did 58 7.5 mg pills so 435mg and blackedout. I woke up after I'm not sure how many hours of "sleep" and found i could barely think and standing up was impossible. I'm 21 and 186lbs so it all depends. Worst part about it after the first 8 pills i didnt even realize i was hurting myself or think of the possibilites. Zopiclonse really impairs u i just kept taking more and more

Its approximately 80 years old. But if its 3 years it 100.
