What type of pesticide exposure occurs through ingestion?

Ingestion of pesticides leads to internal exposure, as it involves the absorption of chemicals directly into the digestive system. When pesticides are consumed, they enter the body's internal systems and can affect various organs and overall health, making this type of exposure particularly concerning. This form of exposure can occur accidentally, such as when pesticide residues are present on food or when someone improperly handles pesticides without adequate cleanliness.

Ocular exposure pertains to contact with the eyes, which is distinct from ingestion since it does not involve the gastrointestinal tract. Dermal exposure involves the skin, where pesticides can be absorbed through various layers, while aural exposure relates to entry into the ears. None of these types involve the internal systems directly through the act of eating or drinking, which is why they do not represent ingestion. Understanding these distinctions is crucial in pest management and safety practices.
