The breathing or inhalation route is significant when discussing pesticide exposure because it allows chemicals to be absorbed directly into the bloodstream through the lungs. When pesticides are inhaled, they can quickly enter the circulatory system, leading to widespread distribution throughout the body. This route can pose a serious risk to various organs, as inhaled substances do not undergo the metabolic processes that can somewhat mitigate harm, which can occur with dermal or oral routes.

When pesticides enter the lungs, they can bypass the body's natural defenses, such as the skin or digestive tract, contributing to potentially acute health effects. The respiratory system has a high surface area for absorption, making it one of the most efficient pathways for harmful substances to enter the body, where they may cause damage to the lungs and other organs as they circulate.

While other routes, such as dermal absorption, ocular exposure, and oral ingestion, can also lead to pesticide exposure and potential organ damage, the inhalation route is particularly critical due to the rapid systemic absorption and the immediate effects that can result from exposure to airborne particulates.
