| LD50 |
Lethal dose 50 percent. Refers to a rating system used to classify the toxicity of pesticides to humans. Specifically, the rating tells how much of a given pesticide must be administered to each memeber of a sample group to kill 50 percent of that group. Therefore, based on this system, the lower the rating, the more dangerous the pesticide is.

| LD50 |
LD stands for lethal dose. LD50 is the amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 can be determined for any route of entry, but dermal (applied to skin) and oral (given by mouth) LD50's are most common. The LD50 is one measure of the short-term poisoning potential of a material. (See also LC50.)
