Which of the following is not a local effect of pesticide exposure?

C is identified as the correct answer because it represents a systemic rather than a local effect of pesticide exposure. Local effects are those that occur at the site of contact with the pesticide, while systemic effects can involve other parts of the body and may result from the pesticide entering the bloodstream.

Skin irritation, eye irritation and injury, and throat irritation are all examples of local effects because they directly involve the specific areas where the pesticide makes contact. Skin irritation occurs where the pesticide touches the skin, eye irritation happens upon contact with the eyes, and throat irritation can result from inhaling or contacting the throat.

Nausea, on the other hand, is a systemic effect that can occur after exposure through ingestion or inhalation, leading to a reaction that affects the whole body rather than a localized area. Understanding this distinction is crucial for recognizing the different types of health impacts that can arise from pesticide exposure and ensuring appropriate safety measures are in place.
