What is the most likely form of pesticide exposure for applicators?

The most likely form of pesticide exposure for applicators is through dermal, or skin, exposure. During the application of pesticides, operators frequently handle equipment, make adjustments, and come into contact with surfaces that may be treated with pesticides. Additionally, products can splatter or drift and come into contact with the skin.

Dermal exposure is particularly significant because the skin can absorb certain pesticides, leading to systemic exposure. Proper personal protective equipment (PPE) like gloves, long sleeves, and protective clothing is essential to minimize this risk.

While inhalation during spraying can occur, especially when using aerosol formulations, dermal exposure is often more prevalent due to the hands-on nature of pesticide applications. Eating food with pesticide residues or drinking contaminated water represents indirect exposure routes that are less likely for applicators directly applying pesticides.
