What are the common exposure routes for pesticides?

The common exposure routes for pesticides include dermal, oral, and inhalation because these pathways represent the primary means through which humans and animals can come into contact with and be affected by pesticide chemicals.

Dermal exposure occurs when the skin comes into direct contact with pesticides, which is particularly significant for those applying these substances or for individuals who may enter treated areas shortly after application.

Oral exposure happens when pesticides are ingested, either accidentally through contaminated hands or surfaces, or intentionally in cases of poisoning. This route is also a concern for children or pets that might ingest pesticide residues.

Inhalation exposure involves breathing in pesticide particles or vapors, which can occur during applications or when pesticides volatilize from treated surfaces. All these routes create pathways for chemicals to enter the body and potentially cause health effects.

The other options provided do not correctly represent common exposure routes in the context of pesticide exposure. Visual, auditory, and olfactory routes relate more to sensory experiences rather than exposure to chemicals.
