LD stands for lethal dose. The 50 stands for 50% of the population. Therefore LD50 means how much of a dose of a drug is required to cause death in 50% of the tested population. Hope this helps.

LD is "Lethal Dose", while 50 shows the percentage of organism that will die at the specified dosage. In MSDS, it usually written like this: LD50 (oral,rat): x mg....which means that the substance at a dose of x mg is lethal to 50% of experimental rat.

Shorthand for dose expected to cause 50 percent death for a specified species, usually with one dose. It is a starting point for evaluating the toxicity of chemicals.
