What is the most common route of pesticide exposure for pesticide handlers?

The most common route of pesticide exposure for pesticide handlers is dermal exposure, which occurs when pesticides come into contact with the skin. During handling, mixing, and applying pesticides, workers often encounter spills or splashes that can lead to absorption through the skin. This type of exposure is significant because the skin can absorb harmful chemicals, potentially leading to systemic effects on the handler's health.

Pesticide handlers are typically advised to wear protective clothing and gear to minimize this type of exposure. This includes gloves, long-sleeved shirts, and protective footwear. Understanding that most pesticide exposure happens through the skin underscores the importance of safety measures and personal protective equipment in preventing harmful effects from pesticide exposure.

Other routes such as oral, inhalation, and ocular exposure are also risks but are less common compared to dermal exposure. For instance, oral exposure could happen if handlers do not wash their hands after handling pesticides and then eat or drink, while inhalation could occur if chemicals are aerosolized during application. Ocular exposure can happen if pesticides splash into eyes, but this is generally less frequent than skin contact. Thus, emphasizing dermal exposure as the primary concern highlights the critical need for protective practices in the field.
