Which of the following best defines tolerance as the ability to withstand pesticide exposure and not be injured?

• A. The amount of food consumed at a single sitting.
• B. The ability to withstand pesticide exposure and not be injured.
• C. Something that varies between different people, depending on health status.
• D. A pesticide remaining immediately after an application.

Answer: (B)

Tolerance is the ability to withstand pesticide exposure and not be injured. This means how well a person or organism can endure contact with a pesticide without harm under typical use conditions, guiding the level of protection and safe handling steps needed. It’s not about how much food someone eats, and it’s not simply about differences in health status that affect sensitivity; those differences speak to susceptibility, not the capacity to avoid injury at a given exposure. It’s also not about pesticide residue remaining after application, which concerns persistence rather than the body's tolerance to exposure.
