The median infective dose (ID 50) is the number of organisms received by a person or test animal qualified by the route of administration (e.g., 1,200 org/man per oral). Because of the difficulties in counting actual organisms in a dose, infective doses may be expressed in terms of biological assay, such as the number of LD 50 s to some test ...
Massacre, mass murder or spree killing – the killing of many people. Murder – the malicious and unlawful killing of a human by another human. Manslaughter - murder, but under legally mitigating circumstances. Omnicide – the act of killing all humans, to create intentional extinction of the human species (Latin: omni "all, everyone").
Incapacitating agent is a chemical or biological agent which renders a person unable to harm themselves or others, regardless of consciousness. [1]Lethal agents are primarily intended to kill, but incapacitating agents can also kill if administered in a potent enough dose, or in certain scenarios.
In toxicology, the lethal dose (LD) is an indication of the lethal toxicity of a given substance or type of radiation.Because resistance varies from one individual to another, the "lethal dose" represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die.
Humans have been lucky when it comes to avoiding sizeable meteors and mass die-offs. However, if one measuring 50-meters-wide and speeding towards Earth at roughly 9 miles per second exploded in ...
The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...

The expected LD100 dose (human) for potassium cyanide is 200–300 mg while the median lethal dose LD50 is estimated at 140 mg. [16] People who killed themselves, were killed, or killed someone else using potassium cyanide include: Viktor Meyer, 19th-century German chemist, died by suicide in 1897 after taking cyanide [17]
