Which route of pesticide exposure is considered the most common for handlers?

1. Inhalation

2. Ocular

3. Dermal

4. Oral

The correct answer is: Dermal

The most common route of pesticide exposure for handlers is dermal exposure. This occurs when the skin comes into contact with pesticides, which is particularly relevant for workers who mix, load, or apply these chemicals. Due to the nature of their work, handlers often have direct skin contact with pesticides, making this route a significant concern. Understanding the specifics of this exposure route is important for handlers to take appropriate safety measures. The skin can absorb a wide variety of chemicals, so any task involving pesticides, whether spraying or transferring them, puts handlers at risk for dermal exposure. This entry route is often more prevalent compared to others due to the handling practices that sometimes may not involve protective gear or appropriate precautions. Inhalation can be a concern, especially in confined spaces or when aerosolized, and ocular exposure can happen if pesticides splash into the eyes. Oral exposure is far less common in professional settings but may occur if proper hygiene practices are not followed. However, dermal exposure remains the leading concern for handlers due to the frequency and ease of skin contact with these substances.
