Which two routes are most important for pesticide entry into the body?

The most important routes for pesticide entry into the body are dermal and inhalation. This is because pesticides can penetrate the skin (dermal route) and be absorbed into the bloodstream directly, which can lead to systemic exposure. The skin is a significant barrier, but certain factors such as the chemical properties of the pesticide and the condition of the skin can enhance absorption.

Inhalation is another critical route, as breathing in pesticide aerosol particles or vapors allows for rapid absorption through the respiratory tract. This route can lead to immediate effects since the lungs have a large surface area and allow direct access to the bloodstream.

These two routes are especially concerning in occupational settings where pesticide applicators might be exposed to concentrated forms of these substances. Understanding these routes helps in implementing safety measures to minimize exposure and protect health.
