What are the two most important routes of entry for pesticide exposure?

The two most important routes of entry for pesticide exposure being dermal and inhalation reflects how these substances typically affect individuals who handle or are near them.

Dermal exposure occurs when pesticides come into contact with the skin. The skin is a significant entry point for many chemicals, including pesticides, especially when there are cuts, abrasions, or prolonged contact. In many pest control situations, handlers may touch treated surfaces or come into contact with overspray, leading to absorption through the skin.

Inhalation is another critical route of exposure, particularly for those applying pesticides in aerosol forms or working in closed environments where pesticide vapors can accumulate. When pesticides are inhaled, they quickly enter the respiratory system and can lead to systemic effects throughout the body.

Together, these routes are particularly relevant for pesticide applicators and others who may be exposed regularly, making understanding and mitigating these risks essential. Other options may refer to relevant routes, but they do not capture the primary pathways for pesticide exposure as effectively as dermal and inhalation.
