What are common symptoms of pesticide exposure in humans?

Pesticide exposure in humans can manifest through a variety of symptoms, and headaches, dizziness, nausea, and skin irritation are well-documented indicators of potential poisoning or sensitivity to these chemical substances. Headaches may arise from neurotoxic effects, while dizziness can suggest impacts on nervous system function. Nausea typically relates to gastrointestinal irritation or systemic toxicity, and skin irritation may occur due to direct contact with pesticides, indicating a localized allergic or inflammatory reaction.

In contrast, other options present symptoms that are less commonly associated with pesticide exposure. Fever and chills, for example, may suggest an infectious process rather than a toxicological one. Increased appetite does not correlate with pesticide exposure, which usually induces opposite effects such as nausea and loss of appetite. Symptoms like fatigue, insomnia, and joint pain might be linked to other health issues but are not primary indicators of pesticide exposure. Overall, the correct answer accurately reflects symptoms that align with recognized health effects associated with pesticide contact or inhalation.
