What is the most likely route of entry into the body of the applicator when handling pesticides?

While dermal exposure is indeed a significant route of entry for pesticides, especially during handling, inhalation is often considered the most likely route of entry in practical settings. When applying pesticides, especially in the form of sprays or aerosols, fine particles can become airborne, making inhalation a critical concern for applicators.

Inhalation can occur when the applicator breathes in pesticide mists, vapors, or dust, which can lead to acute or chronic health issues depending on the toxicity of the substance. While dermal exposure is a valid concern—especially when working with liquid formulations that can come into contact with the skin—many applicators may be more at risk through breathing in airborne pesticide particles.

Understanding the various routes of entry helps in assessing risk and underscores the importance of safety measures such as wearing appropriate respirators, gloves, and protective clothing. The focus on inhalation highlights the significance of air quality and the potential for respiratory exposure in pesticide application scenarios, making it crucial for applicators to take proactive measures to safeguard their health.
