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. LD 50 figures are frequently used as a general indicator of a substance's acute toxicity. A lower LD 50 is indicative of higher toxicity.
Lethal dose (LD 50) is the amount of an ingested substance that kills 50 percent of a test sample. It is expressed in mg/kg, or milligrams of substance per kilogram of body weight. Common name Toxin Lethal doses Description Toxic response Aspirin Acetyl- salicylic acid C 9 H 8 O 4 LD 50 200 mg/kg (rat, oral) Odorless white crystal

This online calculator will give the known LD50 (median lethal dose) value of Caffeine given any mass. LD50 is measured in units of mg/kg and represents the amount of a substance necessary to have lethal consequences in half of the affected population...
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 ...
11 de feb. de 2018 · Specifically, the LD50 represents the dose at which a substance is lethal for 50% of tested subjects. This value is then used as an indicator of a substance’s relative toxicity. Thus, a substance with a high LD50 would have a low toxicity, while a substance with a low LD50 would have a high toxicity.
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.
