What is the most common route of entry for pesticides into the body?

The dermal route, or skin absorption, is considered the most common way pesticides enter the body. This is due to the fact that many pesticides are formulated to penetrate the skin easily, especially when there are cuts or abrasions present. When applying pesticides, especially in a professional context, workers may come into direct contact with the chemicals, which can then be absorbed through the skin.

Inhalation, ingestion, and conjunctival exposure can also be routes of entry, but they are generally less common in the context of routine pesticide application. Inhalation typically occurs when pesticides are aerosolized, while ingestion might happen accidentally or through improper handling. Conjunctival exposure involves substances entering through the eyes, but it is a less frequent route compared to skin absorption during standard pesticide use. Therefore, understanding dermal exposure is crucial for ensuring safety in pesticide application and minimizing health risks.
