What is the most common way pesticides enter the body?

The most common way pesticides enter the body is through the skin. This is particularly relevant in agricultural settings where workers may come into direct contact with pesticide products. The skin is a major route of exposure because it can absorb chemicals, leading to systemic effects within the body. Factors such as the concentration of the pesticide, the duration of skin contact, and the condition of the skin itself (e.g., cuts or irritation) can increase absorption rates.

In comparison, while swallowing (ingestion), inhalation (breathing in), and exposure through the eyes can also occur, they typically represent less frequent or less likely routes of entry compared to dermal absorption. Inhalation may be significant when working with aerosolized pesticides, and ingestion might occur particularly in cases of accidental ingestion or failure to wash hands properly after applying pesticides. However, dermal exposure remains the predominant route for most pesticide-related exposures, especially in occupational settings.
