Which statement about pesticide exposure routes is true?

The statement indicating that 97% of body exposure to pesticides during spraying is by inhalation is accurate because inhalation is one of the primary routes of pesticide exposure, particularly in agricultural settings where chemicals are applied in the air. This route of exposure can result in a significant amount of the pesticide entering the body rapidly. When pesticides are sprayed, they become airborne, and the respiratory system can absorb them more easily compared to other exposure routes.

Inhalation is especially concerning because the lungs have a vast surface area for absorption and can facilitate the entry of harmful substances directly into the bloodstream. Proper use of personal protective equipment, such as respirators, is critical to mitigate this risk during pesticide applications.

Understanding the primary route of exposure helps highlight the importance of safety practices in handling pesticides, including ensuring adequate ventilation, using protective clothing, and following guidelines to limit inhalation exposure during applications. The other statements do not accurately represent the risk and mechanics of pesticide exposure.
