North Carolina Pesticide Application Practice Test

Which of these is a common sign of contact effects from pesticide exposure?

1. Headaches

2. Back pain

3. Itchy skin

4. Nausea

The correct answer is: Itchy skin

Itchy skin is a common sign of contact effects from pesticide exposure because it often indicates a localized reaction to chemicals. When pesticides come into direct contact with the skin, they can cause irritation, leading to symptoms such as itching or rashes. This response occurs due to the irritating properties of many pesticides, which can break down the skin barrier or cause an allergic reaction. While other symptoms like headaches, back pain, and nausea can be associated with pesticide exposure, they are generally linked to systemic effects rather than direct contact. Headaches might result from inhalation or exposure to fumes, while nausea typically reflects internal exposure or ingestion. Back pain is less commonly associated with pesticide exposure and is likely related to other factors. Understanding the nature of these effects can help in recognizing symptoms and taking appropriate action if exposed to pesticides.
