What are the four primary routes through which pesticides can contact the body?

1. Oral, inhalation, ocular, dermal

2. Oral, skin, breathing, touch

3. Ingestion, breathing, vision, absorption

4. Injection, ingestion, inhalation, absorption

The correct answer is: Oral, inhalation, ocular, dermal

The four primary routes through which pesticides can contact the body are oral, inhalation, ocular, and dermal. This is because these routes represent the main ways in which chemicals can enter the human body and potentially cause harm. - **Oral** refers to ingestion, where pesticides can enter the digestive system through eating or drinking contaminated substances. This is significant as many people may inadvertently consume pesticides if proper safety measures are not taken. - **Inhalation** involves breathing in pesticide vapors or particles. This route is particularly concerning in occupational settings or during pesticide application, where airborne chemicals can easily be inhaled. - **Ocular** indicates exposure through the eyes, which can occur if pesticides are splashed or drift into the eyes. The eyes are sensitive and can be easily damaged by chemical exposure, making this route an important consideration for safety protocols. - **Dermal** means contact through the skin. Since skin can absorb pesticides, this route poses significant risk, especially if protective clothing is not worn during handling and application. Together, these four routes encapsulate the primary mechanisms of pesticide exposure, highlighting the importance of using safety precautions and protective equipment to mitigate the risks associated with handling these chemicals.
