What are the common routes of exposure to pesticides?

1. Oral, nasal, ocular

2. Oral, respiratory, dermal

3. Dermal, intravenous, oral

4. Inhalation, dermal, transdermal

The correct answer is: Oral, respiratory, dermal

The common routes of exposure to pesticides include oral, respiratory, and dermal pathways. Understanding these routes is crucial for both safety and effective management of pesticide application. Oral exposure occurs when pesticides are accidentally ingested, which can happen if hands are not properly washed after handling pesticides or if food or drink contaminated with pesticide residues is consumed. Respiratory exposure refers to inhaling pesticide vapors, aerosols, or particles, which can occur during application or when pesticides are used in enclosed spaces without adequate ventilation. Dermal exposure happens when pesticides come into contact with the skin. This is a significant route because the skin can absorb pesticides, leading to systemic effects or localized irritation depending on the chemical properties of the pesticide. These routes highlight the importance of proper handling, application techniques, and protective equipment to minimize the risk of exposure and ensure safe practices in pesticide use.
