Which of the following is NOT a method of pesticide exposure?

Cellular exposure is not recognized as a standard method of pesticide exposure in the same way that inhalation, oral, and dermal exposures are. Inhalation exposure occurs when pesticide particles are breathed in, which can happen during spraying or when pesticides become airborne. Oral exposure refers to ingestion, where pesticides enter the body through the mouth, typically through contaminated food or water. Dermal exposure involves pesticides coming into contact with the skin, which can lead to absorption through the skin barrier. Cellular exposure, on the other hand, does not correspond to a distinct route of exposure; instead, it is more about what happens at the cellular level once a substance has entered the body. Therefore, it does not fit within the categorized methods of pesticide exposure.
