How can pesticides enter the human body?

Pesticides can enter the human body through several pathways, making option B the correct choice. There are three primary ways this can happen: inhalation, ingestion, and dermal absorption.

Inhalation occurs when pesticide particles or vapors are breathed in, which can happen during application or in contaminated environments. Ingestion happens when pesticides are swallowed, potentially through consuming contaminated food, drinks, or using contaminated utensils. Dermal absorption refers to the absorption of pesticides through the skin, which can occur during handling or applying these chemicals.

Each of these routes of exposure can be significant depending on the pesticide formulation and the circumstances of use. Recognizing the various ways pesticides can enter the body is crucial for effective safety practices and health monitoring. Other options limit the modes of entry to only one or two routes, which does not accurately reflect the diverse ways pesticides can impact human health.
