Which of the following is a common effect of pesticide exposure on the skin?

Skin irritation is a common effect of pesticide exposure because many pesticides contain chemicals that can be caustic or irritating to the skin. When skin comes into contact with these substances, it can result in a range of reactions, including redness, itching, rashes, or even burning sensations. Such reactions occur due to the chemical properties of the pesticide, which may disrupt the skin's protective barrier, leading to inflammation and discomfort.

In contrast, while respiratory distress, nausea, and loss of consciousness are concerns related to pesticide exposure, they typically arise from inhalation or ingestion of the chemicals rather than direct contact with the skin. These systemic symptoms highlight the importance of proper handling and application of pesticides to minimize risk to health, but they do not directly relate to the skin's response to exposure. Thus, skin irritation is specifically tied to the direct action of pesticides on the skin.
