What is the most likely way that an applicator is exposed to pesticides?

Inhalation during spraying is the most likely way that an applicator is exposed to pesticides primarily due to the nature of aerosolized chemicals. When pesticides are applied as sprays, they can become airborne particles or vapors that can easily be inhaled. Applicators often work in environments where pesticide sprays are released into the air, making it probable that they will breathe in these products directly. Additionally, because of the potential for fine droplets to remain airborne for a period of time, inhalation represents a significant route of exposure, especially if proper protective equipment, such as masks or respirators, isn't used.

While direct skin contact, ingestion, and touching contaminated surfaces are all valid routes of exposure, they generally occur less frequently during the application process itself compared to inhalation. This is particularly true during active spraying, when the aerosolized particles are generated, creating a higher likelihood of inhalation as opposed to the other exposure routes. Understanding the primary exposure risks helps applicators adopt appropriate safety measures, such as using proper ventilation and personal protective equipment, to minimize their risk.
