What are the three routes by which pesticides can enter the body?

The three routes by which pesticides can enter the body are oral, dermal, and inhalation. This means that pesticides can be absorbed through the mouth (oral), through the skin (dermal), or through the respiratory system (inhalation).

Oral exposure occurs when pesticides are ingested, which can happen through consumption of contaminated food or drink, or accidentally ingesting residues. Dermal exposure refers to the absorption of pesticides through the skin, which is a common concern for individuals who apply pesticides without proper protective gear. Inhalation involves breathing in pesticide particles or vapors, which can occur during spraying or when handling pesticide containers.

The other options mention routes such as ocular (involving the eyes) or generally use different terms for the same routes, but they do not encompass the three primary and most significant routes of exposure recognized in pesticide safety. Understanding these entry routes is crucial for implementing proper safety measures and protective practices when handling pesticides in horticulture.
