What is the most common route of exposure for pesticide handlers?

The most common route of exposure for pesticide handlers is through dermal absorption. This occurs when pesticides come into contact with the skin during handling, mixing, or applying products. Given that skin is a large surface area and can absorb various substances, pesticide handlers are often at risk of dermal exposure, especially if proper protective equipment is not utilized or if there are spills or leaks.

In the context of pesticide handling, dermal exposure can occur from splashes, drips, or residues that settle on the skin. Pesticides can penetrate the skin and enter the bloodstream, which makes understanding and minimizing this risk crucial for those working with these chemicals. Proper personal protective equipment (PPE) like gloves, long sleeves, and protective suits is essential to reduce the likelihood of dermal exposure.

Other routes, such as inhalation and ocular exposure, are also important for handlers to be aware of, but they are statistically less common compared to dermal exposure. Oral exposure often occurs accidentally, but handlers are typically trained to avoid eating or drinking in pesticide applications, which further reduces this risk.
