Why is dermal exposure a significant concern for pesticide handlers?

1. It's the least serious form of exposure

2. It's uncommon among handlers

3. It's the most common route of exposure

4. It's always avoidable

The correct answer is: It's the most common route of exposure

Dermal exposure is a significant concern for pesticide handlers primarily because it is the most common route of exposure. Pesticides can easily be absorbed through the skin, potentially leading to systemic toxicity. Unlike inhalation or ingestion, which may require specific conditions to occur, dermal exposure can happen frequently as handlers mix, apply, or spray pesticides, often without realizing it. Skin contact can occur through splashes, spills, or simply handling contaminated equipment. Thus, understanding and mitigating dermal exposure is critical in protecting the health and safety of those who work with these chemicals.
