The term that describes the measure of how poisonous a pesticide is to a living organism is?

• A. Toxicity
• B. Exposure
• C. Antidote
• D. Fumes

Answer: (A)

Toxicity is the measure of how poisonous a pesticide is to a living organism. This term captures the inherent potential of the chemical to cause harm, often expressed by metrics like LD50 or LC50 that compare how much of the substance is needed to produce harm or death in a test population. A lower LD50 means higher toxicity, while a higher LD50 means lower toxicity. It’s important to note that toxicity describes what the chemical is capable of doing, whereas exposure describes how much contact occurs with the organism and over what duration. For example, a highly toxic pesticide can be less dangerous in practice if exposure is minimal, and a less toxic pesticide can still be hazardous if exposure is extensive. The other terms don’t describe this inherent poisonous strength: exposure refers to contact levels, an antidote would be a remedy, and fumes are a form of the pesticide's release, not a measure of its poison strength.
