Pest Control Technician Practice Exam

What are the primary routes of pesticide entry into the body?

1. Oral, Intravenous, Dermal

2. Oral, Dermal, Inhalation

3. Dermal, Topical, Ingestion

4. Inhalation, Oral, Absorption

The correct answer is: Oral, Dermal, Inhalation

Pesticides can enter the body through three primary routes: oral, dermal, and inhalation. Each of these pathways reflects how individuals may be exposed to pesticide formulations in various environments. Oral exposure occurs when pesticides are ingested, either accidentally or intentionally, through contaminated food, drink, or hand-to-mouth contact. This is a significant route of exposure, particularly in households or agricultural settings where pesticides are applied. Dermal exposure refers to the entry of pesticides through the skin. This is a common pathway, especially for workers handling pesticides without proper protective gear. Chemicals can be absorbed directly through the skin, making protective equipment essential in preventing exposure. Inhalation is another critical pathway whereby pesticide particles or vapors enter the respiratory system. This can occur during aerosol applications or when working in areas where pesticides have been recently applied, leading to potential respiratory health issues. Understanding these routes is essential for effective pest control and safety management, as it informs both application methods and safety precautions. The other options mention routes that either do not accurately reflect how pesticides typically enter the body or include terms that are not commonly associated with pesticide exposure. For effective pest management, recognizing these primary routes is crucial for minimizing risks to human health and ensuring safe handling practices.
