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

The dermal route is considered the most common entry point for pesticides into the body. This is largely due to the fact that many pesticides come in the form of sprays or powders that can easily come into contact with the skin during application. When pesticides are applied, especially in agricultural or pest control settings, workers may inadvertently expose their skin to these chemicals. Dermal absorption can lead to systemic exposure, especially if protective clothing is not worn or if there is any open skin or abrasions.

The skin acts as a barrier to some extent, but certain chemicals can penetrate it depending on their formulation and the condition of the skin. This makes it crucial for applicators to understand the risks associated with dermal exposure and to utilize personal protective equipment to minimize contact. Understanding this helps in promoting safety measures that reduce the likelihood of pesticide exposure and ensuring that applicators are well-informed about the proper handling of these substances.
