What is the most common route of pesticide poisoning for applicators?

The most common route of pesticide poisoning for applicators is dermal exposure. This occurs when pesticides come into contact with the skin, which is a large and absorbent surface area. Applicators often handle pesticides directly, and if they do not wear appropriate protective equipment, such as gloves or long-sleeved clothing, they increase the risk of these chemicals penetrating the skin. Pesticides can be absorbed through the dermal layers into the bloodstream, leading to health issues ranging from mild irritation to severe poisoning depending on the toxicity of the compound and the extent of exposure.

While inhalation, ingestion, and eye contact are also routes of exposure, they tend to occur less frequently in applicators compared to dermal exposure. Inhalation of pesticide vapors or aerosols can occur, especially in poorly ventilated spaces, but it usually requires specific conditions, such as applying pesticides in mist or vapor form. Ingestion is typically associated with accidental swallowing, which is less common in professional applications due to safety training and precautions. Eye contact can happen if applicators do not wear proper eye protection, but it is generally less frequent compared to skin exposure during application. Therefore, dermal exposure remains the predominant route for pesticide poisoning among applicators.
