In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
Se define como la cantidad de una sustancia que, cuando se administra a un grupo de animales de prueba, causa la muerte del 50% de ellos dentro de un período de tiempo determinado, generalmente 24 horas. La LD50 se expresa en miligramos de sustancia por kilogramo de peso corporal (mg/kg).
9 de mar. de 2021 · Lethal dose (LD) The dose of radiation expected to cause death to 50 percent of an exposed population within 30 days (LD 50/30). Typically, the LD 50/30 is in the range from 400 to 450 rem (4 to 5 sieverts) received over a very short period.
The median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 (lethal concentration and time) of a toxin, radiation, or pathogen is the dose required to kill half the members of a tested population after a specified test duration.
31 de ago. de 2022 · LD50 es la dosis letal media de una sustancia química que mata el 50% de una población de prueba. Aprende cómo se mide, se interpreta y se compara la toxicidad de una sustancia según su LD50.
Hace 5 días · LD 50 and LC 50 are measures of acute toxicity that indicate the amount or concentration of a chemical that kills or harms 50% of test animals. Learn how these values are determined, compared and used for occupational health and safety purposes.
The LD 50 is the dose that kills half (50%) of the animals tested (LD = "lethal dose"). It is a standardized measure for expressing and comparing the toxicity of chemicals. LD 50 values are given for common drugs (e.g. ibuprofen and aspirin), common household ingredients including water, table sugar (sucrose), salt (sodium chloride ...
