Lethal Dose Fifty (LD50) is one way the toxicity of chemicals are measured. LD50 is the amount of a pesticide that has killed half of the animals in a laboratory test. The LD50 is found for both dermal and oral routes of exposure.he acute toxicity of a pesticide is used as the basis for the warning statements on the label. Acute toxicity may be measured as acute oral toxicity, acute dermal toxicity, and acute inhalation toxicity. Chronic toxicity is the delayed poisonous effect from exposure to a substance.
