How do most pesticides typically enter the body?

Most pesticides typically enter the body through absorption via the skin. This method of entry is significant because many pesticides are designed to be effective when they come into contact with plant surfaces or pests, and they can also penetrate human skin. Skin absorption is a common pathway for chemicals, and various factors such as the chemical structure of the pesticide, the condition of the skin, and the duration of exposure can all influence the extent of absorption.

In agricultural settings, workers often handle pesticides directly without adequate protective gear, increasing the risk of dermal exposure. Understanding this route of entry highlights the importance of using appropriate personal protective equipment (PPE) and adhering to safety guidelines to limit skin exposure when handling these substances.

While inhalation and ingestion are also potential routes of exposure for pesticides, the primary and most significant route in many practical situations, especially during application, is through the skin. Direct injection is a much less common method of exposure in the context of pesticide application and is typically associated with medical scenarios rather than agricultural practices.
