What is the most common route of pesticide entry into the body?

The most common route of pesticide entry into the body is through skin contact. The skin is a large organ and can absorb many substances, including pesticides, especially if the skin is damaged or if the pesticide is in a form that is easily absorbed (such as oils or solvents). This pathway is particularly concerning because small amounts of pesticides can enter the bloodstream through the dermal layers, leading to potential systemic exposure.

While inhalation, oral ingestion, and exposure through the eyes can also result in pesticide entry, studies and occupational exposure data indicate that skin contact often represents the highest risk for many people, especially those working in agricultural settings or during the application of pesticides. Ensuring proper personal protective equipment and hygiene practices can help mitigate this primary exposure route.
