What is the most common route of pesticide exposure?

The most common route of pesticide exposure is dermal (skin) exposure. This is primarily due to the fact that many individuals come into contact with pesticides through handling, mixing, or applying these substances without adequate protective gear. Skin can absorb chemicals, allowing them to enter the bloodstream, which can be a significant risk unless precautions are taken to wear proper clothing and gloves.

While other routes of exposure such as ingestion, aerial drift, and inhalation are important to consider, they generally occur less frequently among pesticide applicators. Ingestion typically requires a more direct action (e.g., eating or drinking contaminated food or water), while aerial drift concerns primarily agricultural settings where pesticides are applied via aircraft and may affect areas far from the target site. Inhalation, while a valid concern during applications or when wind carries particulates, generally represents a lower risk compared to direct contact with the skin.

Understanding these exposure routes helps pesticide applicators plan effective safety measures to minimize risk, emphasizing the importance of protective gear to prevent dermal contact.
