The median lethal dose, or LD 50, of alpha-thujone, the more active of the two isomers, in mice, is around 45 mg / kg, with 0 % mortality rate at 30 mg / kg and 100 % at 60 mg / kg.
32.
This list included a ban on the use of animals in tests for cosmetics, tobacco, alcohol products; warfare experiments; psychological and behavioural tests; a ban on the Median lethal dose and Draize eye irritancy tests, as well as other measures in relation to the administration of the legislation.
33.
The median lethal dose ( LD 50 ) for 30 days in dogs after intravenous injection of plutonium is 0.32 milligram per kg of body mass, and thus the lethal dose for humans is approximately 22 mg for a person weighing 70 kg; the amount for respiratory exposure should be approximately four times greater.
34.
A case of a fatal poisoning of an adult with 4 grams of sodium fluoride is documented, For sodium fluorosilicate ( Na 2 SiF 6 ), the median lethal dose ( LD 50 ) orally in rats is 0.125 g / kg, corresponding to 12.5 g for a 100 kg adult.
35.
Primary measurement endpoint derived from the acute oral and acute contact toxicity studies is the median lethal dose for 50 % of the organisms tested ( i . e ., ), and if any biological effects and abnormal responses appear, including sub-lethal effects, other than the mortality, it should be reported.
36.
In a study performed by Plewa, et al ., IAA was determined to be one of the most cytotoxic of those studied, with a median lethal dose on the order of magnitude of 10 " 5 M . It was the most genotoxic of more than 60 DBPs studied and is the most genotoxic DBP identified thus far.
37.
The pulse of neutron radiation would cause immediate and permanent incapacitation to unprotected outdoor humans in the open out to 900 meters, with death occurring in one or two days . The median lethal dose ( LD 50 ) of 600 rads would extend to between 1350 and 1400 meters for those unprotected and outdoors, where approximately half of those exposed would die of radiation sickness after several weeks.
38.
The median lethal dose ( LD 50 ), subcutaneous ( the most applicable to actual bites ) for mice is 0.025 mg / kg Compared to the beaked sea snake ( " Enhydrina schistosa " ) 0.164 mg / kg, Indian cobra 0.565 mg / kg, North American eastern diamondback rattlesnake 11.4 mg / kg, etc .,
39.
If as little as 10 mL of pure methanol is ingested, for example, it can break down into formic acid, which can cause permanent blindness by destruction of the optic nerve, and 30 mL is potentially fatal, although the median lethal dose is typically 100 mL ( 3.4 fl oz ) ( i . e . 1 2 mL / kg body weight of pure methanol ).
40.
The potency of different venoms varies; lethal venoms are often characterised by the median lethal dose ( LD 50, LD50, or LD-50 ), expressed in terms of mass fraction ( " e . g . ", milligrams of toxin per kilogram of body mass ), that will kill 50 % of the target of a specified type ( " e . g . ", laboratory mice ).
